Wetlands is important to wildlife because they have food shelter and wetlands clean water. I i know that wetlands cleans ditry water because in my lab i did the experiment, and there was less dirt water the water then there was before i put it through the wetland model. Plus my friend that was doing the same experiment also found less dirt in there water after putting it through their modeled wetland.

1. Why are wetlands important to humans? Wetlands are important to humans because they help our environment to clean natural areas, The protection of our wetlands has been strengthed by recent changes to provincial policies and legislation. They also help our nature, and animals surrounding us. Also, wetlands are specifically valuable to people as places for recreational and educational activities such as hunting, fishing, camping, and wildlife observation. Wetlands are often filled by humans for everything from economic values.

My Wetland Experiment:

Do wetlands clean water?

Hypothesis: No, because there are a lot of junk, gross, and bacteria in the water. And yes, wetlands do have clean water, because if they clean everything in the water, it would be clean, but we should not go in the wetland water, because we wouldn't know if it's deep or not.

Materials List:
- Aluminum tray
- Green clay
- Water (dirty)
- Sponge
- Dish scrubber
- Beaker
- Microscope
- Microscope slide
- Thistle tube
- Flask
- funnel
- stop watch
- Cover slip

Procedure:
1.Collected materials
2.Got pan, and put clay half way
3.Put sponge right beside clay
4.Poured water down, and start stop watch
5.Stop the stop watch
6.Drew diagrams shown what happened to the sponge
7.Gathered beaker and put flask on top, poured all dirty water in the beaker
8.Took out sponge and put dish scrubber
9.Poured dirty water again, start stop watch
10.Stop the stop watch, and take out the dirty water and pour it into the funnel
11.Draw diagrams and record data
12.Then get microscope, to see the dirty water
13.Got the microscope slide, and placed it on the microscope
14.Then, get thistle tube, and get the water from beaker and put it on slide
15.Then look in the microscope to see anything and draw it down
16.Clean slide and then get water from funnel
17.Check anything, and draw them out
18.Collected data (diagram, bar graph)
19.Observation chart
20.Conclusion

Conclusion: My hypothesis was correct, and I found out that, while I was doing my experiment, the dirty water was all in the sponge. And when you squeeze it, some of the dirty water comes out, and some don’t. When I was using the dish scrubber, the scrubber, wasn’t wet at all. It just floated on top and nothing happened.

Mr.Dobbie, I’m going to hand in my observation chart, my data, and my microscope check on Tuesday.

Mr.Dobbie as you know me and my partner didn't finish our experiment, so im not going to have any resarch from my experiment, im just going to use some resarch i have about wetlands.

1.Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites).

Wetlands are important to humans because they help our environment to clean natural areas.Also wetlands help keep the river level normal and filter the purify the surface water.Many of the animals that live in the habitats use wetlands for migration or reproduction.Wetlands also clean the water by filtering out sedimentation, decomposing vegetative matter and converting chemicals into useable form.

question 1:1. Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

Procedure: Experiment #1
1.Gathered all the materials.
2.grabbed the tin.
3.Filled half the tin with clay. (had a graduating slope)
4Put a sponge at the bottom of the slope, after it was pre soaked.
5Poured 50 mL of water down the slope, through the sponge.
6.Collected a sample in a pipette.
7.Cleaned out the container with soap and water.
8.Poured 100 mL down the slope, through the sponge.
9.Collected a sample with second pipette.
10.Compared both samples with a magnifying glass, then compared then to the dirty Gathered materials.

2.Weighed filter paper on the triple beam scale.
3.Written down weight.
4.Put a funnel in beaker.
5.Put filter paper in the funnel.
6.Poured in first sample of water from experiment number 1.
7.Repeated step 4 and 5.
8.Poured in second sample of water from experiment 1.
9.Let the water dry on filter paper.
10.Measured weight of both filter papers.
11.Subtracted from original weight.
12.Checked if the filter paper with more in it had more pollutants or not.
13.Then wrote it down in observations.
12.water.(not put through the sponge)
13.Recorded observations.

answer to quastion below.

!. wetlands help humans by holding much water so flooding wont occur. this means more land for us to make homes on.
2. wetlans also filter water so even if we pollute a litttle our water supply won't be to dirty and we won't kill marine life or poison it.

3. if we eat fish that is poisoned the poison will be passed on. the poison comes from the stuff we throw in lakes. wetlands stop this though.

reference for this:http://www.mbgnet.net/fresh/wetlands/why.htm

4. wetland also removes and store green house gases from the atmosphere.

reference for this:http://environment.about.com/od/environmentallawpolicy/a/wetlands_protec.htm

5. people with no fresh water can go find a wetland and drink water from there. it still isn't completely clean, but it is still good enough to drink. with out te wetlands these people have no other alternatives.

6. rice is also sometimes grown in man made wetlands.

7.the reference for this: http://www.wwt.org.uk/our-work/wetlands-and-people/why-people-need-wetlands

8.wetlands provide us with some oxygen they cover little less then 10 % of the planet.

9. the wetland's dense vegetation creates a tough buffer zone that can deflect waves and other heavy water surges that might otherwise erode shorelines and threaten human habitations.

i was able to make a video i did not record my experiment, i will next time.

i am not sure what rubric to use. i think rubric 4 is the best though.

2. What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment?
I would like to be marked with rubric #3.

Procedure:
1.Took a container and pressed clay on to it,to make a decline.
2.When done, at the bottom of the decline placed the scouring pad.
3.Looked at water under a microscope at high power and recorded observations in observation chart.
4.Poured dirty water into a 150mL beaker up to 100mL.
5.poured dirty water into 250mL beaker up to 200mL.
6.Poured water that is in the 150mL beaker at a 180 degree angle, at the edgeof the container.
7.Let water settle behind the scouring pad.
8.Observed the water beyond the scouring pad with a magnifying glass and recorded them in the observation chart.
9.Then observed the water under a microscope at high power and recorded observations in the observation chart.
10.Poured water that was in the 250mL beaker at a 180 degree angle at the edge of the container(in other model).
11.Let the water settle behind the scouring pad.
12.Observed water beyond the scouring pad with a magnifing glass and recorded them in the observation chart.
13.Then looked at water water under a microscope at high power and recorded observations in the observation chart.

The controls required in my experiment were to make sure that when I poured the water it was always in a 180 degree angle, make sure it was in the same spot every time and make sure it was accuretly measure to the precise measurement givin in the procedure.These controls were requirede in my experiment because if I didn't make sure that everything was exactley the same-except for the water measurements-then my answer would not be accurate.To maintain these controls I made sure that before I did the eperiment I double checked if the water was up to 100mL.I always made asked my partners to make sure the beaker was at the right spot and that it was at a 180 degree angle.

In the end I found that the amount of water being moved throughout a wetland does affect the purity of the water because in my experiment the least amount of water was the cleanest.

Refences:I used the science textbook to research about wetlands.

2.What controls are required for your experiment?What did you do during your experiment to make sure your controls were maintained?Why are controls required for this experiment?

The controls that were required for this experiment were:
-How much water is used
-How fast it was poured
-How long I hold the litmus paper in my hand
-The type of water I use
-Where the water is poured
-The sponge also has to be cleaned and dried each time I use it.

*What did you do during the experiment to make sure your controls were maintained?

During my experiment i did different things, according to the control to make sure it was under control. For the first one, which was how much water was used. I made sure that I did not Put too much water or too little water.

I made sure that I did not pour to much water because if I did then the water that would impact the purity of the water, after it has passed the sponge.

Another control I had to maintain was how long that I had held the litmus paper. I had to control this because if I held it too long then some of the natural oils and dirt would go onto it.

I had to also control what water i had used. For example if i had I had used water that had already been cleaned then i would not be able to purify it. which would then lead to me not being able to figure out my hypothesis.

I have to control where the water is poured. I have to control this because if i do not then it might cause the water to come out of the tin. Also the water has to go in the path.

The last control that i have to maintain is how clean the sponge is. I have to control this because as the water passes it the water will take/pass it on as well, as in the dirt will get transfered.

*Why are controls required for this experiment?

Controls are necessary in this experiment and play a big role. It is needed because if we did not have them then the experiment would of not have worked out. For an example, say my question was does the amount of water affect the purity? Say that I did not clean my sponge once during the experiment then a lot of dirt would of stayed there. even though i would put a little bit of water there would still be dirt in it because i did not clean the sponge. Therefore the controls are necessary.

Question: Does the amount of water moved through the wetland affect the purity?

Hypothesis:
If the amount of water flowing is a lot then the water will not be as pure.

Materials:
-Clay (1000g or 1/2 pound)
-1 Sponge
-2 Beaker(250)
-Kit 1
-Litmus paper 2
-1 beaker filled with dirty water (250mL)
-Scouring pad
-Microscope Slide 2
- 1 Microscope
-2 Pippettes
-2 Test tubes

Controls:
1)How much water is used
2)How fast I pour it
3)How long I hold the litmus paper for
4)The type of water I used
5)Where the water is poured
6) The sponge also has to be cleaned and dried each time I use it

Procedure:
1)Took out all the materials and placed them on the table.
2)Took clay and moulded and flattened into shape needed. (A hill kind of shape so that there is a slope for the water to go down)
3)Made marks on the clay for the path of the water to flow
4)Placed the sponge and scouring pad together at the tip of the clay.
5)Pushed the Sponge and clay so there was room for the water to be
6)Took the beaker filled with dirty water and poured it into the clean beaker, about 100mL
7)Poured 50mL of the dirty water slowly down the path
8)Took the water after it had passed the sponge and poured it into the test tube.
9)Labeled it a
10)Poured 150mL of dirty water and poured it down the pathway slowly
11)Took the water that passed the sponge and poured it into the other test tube
12)Labeled it b
13)Took tube a and put a drop of water from it onto the microscope slide, using the pippete
14)Put the slide in place in the microscope
15)Looked through and recorded observations
16)Took tube b and put a drop of water onto the slide, using pippete from the tube
17)Looked into the microscope and recorded observation
18)Put away all the materials

***Mr.Dobbie i will give you my observation and data charts at school

I would like to be marked on rubric #3. Question 2. What controls were required during your experiment?

What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment?

What controls were required during your experiment?

- needed measure proper amount of dirty water not clean water
-needed to pour water slowly
- needed to build slope of the wetland properly
- needed to dry up the mat or sponge
- needed to pour water from the STARTING of the slope
- needed all sides covered so water couldn't go trough
- needed to gather all materials
- needed to record my data on my observation sheet
- needed to get the right shapes

What did you do during your experiment to make sure your controls were maintained?

-First of all I needed to build my slope properly so the water maintained balance. I didn't build my slope too high from one side and the other too deep. The slope was connected to my sponge so the water could go straight into it. Made sure that the clay was clean from any dirt.

-Second I needed to measure the right amount of DIRTY water. If I got or poured more water than I need it might overflow my wetland. Overflowing can affect my results and wouldn't get an accurate answer. If I get clean water, there would be no point of my experiment. The main point of my experiment is to see if the shape of a wetland affect its ability to filter the water in the wetland.

- Third I needed to pour the water slowly and carefully. If I pour it fast it might as well go from above it. That will also affect your results as well. If the water would go straight from top you will have to start your experiment all over again. Also make sure your clay and your sponges are clean from any dirt.

Why are controls required for this experiment?

Controls are important in my experiment because without controls I can mess up my results. I wouldn't get a accurate answer for my experiment. If I pour down the water fast it might overflow and get right above the sponge and mess up my answer. Controls is one of the very important step for my experiment. If I had no controls my answer would be all wrong.

Ok, hi mr.dobbie for my assignment i will be recording a video and this time compressing it to a smaller size but anyways here are references

http://www.epa.qld.gov.au/wetlandinfo/site/index.html
*I looked up and took notes on what are wetlands, how to monitor them and facts and figures

http://wer.ifas.ufl.edu/wetlands.htm
*For this website it gave me a lot of research, for instance it told me how wetlands can control flooding & water purification.

http://mystart.incredimail.com/
*This is a search engine i used i typed in "why are wetlands important to wildlife?" I also used google.com for research too.

1. Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)


Hypothesis: Yes, the amount of water will affect the purity of the water.


1. Wetlands are important to humans because they are necessary to plants and animals. The wetlands also support the food chain. Wetland are also homes to many animals, and if there was no wetlands then some of the animals would die because they would have no home, and if they could not survive that would mean that we wouldn't have any meat type of food. Another reason why wetlands are important to humans because having wetlands stops flooding for happening. Wetland also clean out the dirty water that is in the rivers and lakes. That is why wetlands are important.

Hypothesis: No, the amount of water that moved through the wetland will not be pure.

Materials:
1.Clay
2.Beaker
3.Water
4.Magnifying glass
5.Baking tin

1. Wetlands are important to humans beacuse the wetlands support are food chains and are wild life. Wetland also clean out the dirty water that is in are lakes and rivers. Also, wetlands are importand beacuse they are many animals homes, and without there homes the animals would die. It helps us humans beacuse wetlands save are lives by prevent floods from happening.These are some of the resons why wetlands are important to humans.

Question: Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

Wetlands are very important to humans. Without wetlands our pollution would increase extremely. This would pollute our water and food supply. Without wetlands we would have poisoned our water supply a long time ago. Wetlands also supply us with a clean supply of water. The wetlands filter lakes, ponds, and streams. This continues on the food chain because without it all animals would die then humans due to lack of food. Wetlands provide animals with habitats. Wetlands control droughts. Wetlands squeeze the water out when the habitat needs the water.
Wetlands also stop floods by sucking in the water from the flood. Wetlands help with agricultural uses. Wetland let farmers take water to grow crops and food for people and animals to eat. That is why I think wetlands are important to people.

Question:Can wet lands provent the speed flooding.
Hypothesis: Wet lands can decrease the speed of flooding.
Purpose: Can wet lands descrease floding.
Procedure:
1)Place the tray.
2)Take clay and put it on the side of the tray.
3)Place the sponge in the middle of the tray.
4)Pure 200ml of of water on the clay fast.
5)See if the sponge absorbed the water.
6)Write the observation.
7)See if the water goes in the empty part of the tray.
8)Record how slow the water went.
9)Write the observation.
Conclusion: Wet lands do decrease the sped of flooding and my hypothesis is correct.
Wetlands are really important to humans and wildlife. For humans they decrease Wetlands prevent and decrease the speed of flooding by holding water much like a sponge.Humans also use it for camping, bird watching,hunting,fishing,wildlife observation. Wetlands help keep river levels normal and filter and purify the surface water.For animals they give many of them homes and a lot of them migrate, they give animals and humans clean and filtered water plus 150 types of birds and 200types of fish depend on wet lands for there survivel.Many of the endangered species because a lot of them gothere for fresh water, food,shelter, resting places and for breeding.1/3 of the animals there are endangered because they either come there or because of humans trashing and distroing them to make factories, malls,homes and many other things.

Question #3: Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for website).

In my opinion, wetlands are important to wildlife because through my experiment i learned that wetlands are natural filters.Therefore, when animals drink water they usually go to wetlands to drink water.
Moreso, when a wetland overflows onto it's flood plain, it spreads sediment including minerals and soil nutrients, making flood plains the most fertile farming areas in the world. For example, in India or Egypt, there are many dry parts. Over there, flood plains are very important. Benefits of floods occur after the flood waters have gone. It is drained back into the river, soaked into the ground, or evaporated. Then, rich soil is left behind. Leading me to my next point. After all this rich soil is left behind attracting many people to live near or on the flood plain. Because the soil is extremely fertile it is easy to grow crops.
In America, more than 1/3 of the animal species rely on wetlands as their habitat. Over 200 species of birds rely on wetlands for feeding, nesting, foraging ,and roasting. For humans, they provide areas for recreation, education, and aesthetics. More than 98 million people hunt, fish, bird watch, or photograph wildlife. Americans annually spend $59.5 billion on these activities.
Furthermore, wetlands also recharge our underground aquifers-over 70% of Indiana rely on ground water for part of or all their drinking water needs. Wetlands protect our homes from floods; like sponges, they soak up and slowly release flood waters. In addition, Shorelines along rivers, lakes, and streams are protected by wetlands, which hold soil in place, absorb the energy of waves, and buffer strong currents. While conducting my experiment I also noticed that once I filtered my water, the impurities would be under the sponge and would not move unless I washed them out.

I would like to be marked with rubric 4.

What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment?

For me to make my experiment succesful was to mantain the controls of how i did the experiment. Also the material list was the most helpfull and the procedure to help me mantain to the proper controls required.

The controls that were required during the experiment.

*cleaning up after each step

* measuring the right amount of water required to our project

* using the dirty water for most experiments instead of clean water.to test if water was pure or not.

* needed to build a model of a wetland

*had to pour the water in a certain way so that the experiment will be succesful

*had to be organized with our materials

* made sure we did research about the materials i knew what i was doing

* didnt leave the station unsupervised

Does the amount of water move through the wetlands affect the purity of the water?

Materials used:
*microscope
*microscope slide
*100 ml dirty water
*200 ml of dirty water
*small container
*1000 gram clay
*scouring pad

procedure:
* took container and declined the clay to look like a piece of land

*placed scouring pad beside clay to shape the water

*placed a sample of the dirty water on microscope slide then placed to look in microscope on each power

* recorded observation in chart and drew diagrams of what seen in at power

* took two beakers with dirty water one up to 100 ml and other up to 200 ml

*poured the 100 ml of dirty water slowly at the edge of the container

*observed the water and recorded in observation chart

*took a water sample poured in container and checked in microscope on each power and wrote observation in chart

*after poured the 200 ml of water fast at the edge of the container

*took sample of the 200 ml and checked in microscope at each power

* observed the diffrence of each water poured and wrote observation in chart and drawed diagrams of each sample before and after.

* checked diffrence between the amount of water poured and checked if it made any diffrence to the purity of water

The controls used to mantain the experiment was measurement if i didn't measure my water samples properly the experiment wouldnt be precise because the amount of water poured effected the experiment.Also keeping up with the experiment meaning cleaning up after each step that was another important control to mantain because cleaning during each step will help stay on task. During the experiment i also had to supervise my station at all times that was another control really important for this experiment. Keeping to my station was important so that i can observe everything and keep on track at all times. Those controls were the main once to keep up with during the experiment and staying organized. I also made a check list to mantain all the controls at a right level.

Why are controls required for this experiment?

Controls are required for this experiment because without controls we would be out of task meaning our work wouldn't be as good without controls. Controls are also required for this experiment to help us set some boundries for our project if i didn't have controls i wouldnt know where to start in the project.The experiment i did needed rules to guide me to stay organized and aware of how to follow my procedure.Also without controls our answer wouldn't be as accurate. So overall controls were the main part of my experiment.

refrences: used google, science textbook and friends to help me throughout the project.

i would liked to be marked by rubric #3

2. What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment?

I would like to be marked by rubric number 3.

Question: Does the age/maturity of a wetland affect it's ability to filter pollutants?

Hypothesis: I think that, yes, the age/maturity of a wetland, affects it's ability to filter pollutants.

Materials List:
1. Scouring Pad
2. Sponges
3. Tin Foil
4. Dirty Water
5. Clay
6. Beaker
7. Filter Paper
8. Funnel


Procedure:
1. Gathered all materials.
2. Took some clay, and made it into a slope into half of the kit.
3. Put the sponge at the end of the clay.
4. Put beaker down onto a flat surface.
5. Put funnel down onto beaker.
6. Put filter paper down onto funnel.
7. Measured the filter paper mass.
8. Took dirty water, and poured it over the filter paper, and waited for the dirty water to go in.
9. Waited for the filter paper to dry up.
10. Measured the filter paper, mass and pollutant, once it dried up, calculated pollutant mass.
11. Repeated step 3, 4, 5, 7, 8, 9, but this time, did it with scouring pad.

Safety Cautions:
1. Make sure, you don't touch your eyes, nose, mouth, ears, after touching the dirty water.
2. Make sure, you don't spill your water onto anything.
3. Make sure you clean up after yourself.
4. Carry all of your materials, gently, and carefully.
5. If you, spill anything, make sure, people around you know, and clean it as soon as possible.
6. Return, all of your materials, when you are done with them.

Conclusion: After my experiment, I found out, that my hypothesis was correct. The age/maturity of a wetland does affect it's ability to filter pollutants.

3. Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research.
Wetlands are important to wildlife because they are able to gain energy and provide food for the animals that live in the wetlands. Wetlands also help protect all wildlife from floods. Wetlands are the habitat for the all wildlife living there and all the wildlife depend on the wetland to provide for them. Wetlands also play a part in purifying our water by filtering pollutants. Filtering pollutants was a part of my experiment. The question I was experimenting for was: Does the amount of water moved through the wetland affect the purity of the water? I concluded that the amount of water moved through the wetland did affect its purity. As my observation chart stated after pouring 90ml of water, at a medium speed, down the slope there was 2.4g of particulate leftover. After pouring 50ml of water down the slope there was 1.2g of particulate leftover. That showed me that the amount of water running through the wetland did affect its purity.
Hypothesis: If there is a lot of water than the water wouldn’t be as contaminated as a smaller amount of water would be because the less amount of water the more particulate there is. The more water there is the harder it is to pollute all of the water rather than a smaller amount of water.
Materials List:
1. Tin foil tray
2. Modeling clay
3. A sink
4. Indoor/outdoor carpeting
5. Graduated cylinder
6. 4 paper filters
7. Water (90ml) (90ml) (50ml) (50ml)
Procedure:
1. Gathered all the material
2. Used modeling clay to make a slope
3. Cut the carpeting and put it next to the slope
4. Filtered paper mass with particulate
5. Weighed paper mass on its own
6. Measured 90ml of water
7. Poured he water at a medium speed down the slope
8. Waited until the particulate dried
9. Measured the mass of the particulate
10. Measured another sample of (90ml) of the same kind of water
11. Poured it down the slope
12. Poured the water through a paper filter
13. Repeated steps 6 and 7
14. Recorded my observations from steps 4-12
15. Measured 50ml of water and poured it down the slope and a medium speed
16. Recorded all of my observations
• Found the mass of the filter paper
• Found the mass of the particulates
• Found the mass of the leftover particulate on the pan

1. Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research Rubric # 3
Wetlands help humans in many ways,they soak up water just as a sponge would.Wetlands help purify water which would help humans in a way of drinking it, cleaning etc. In the experiment that was conducted it showed results of a mature wetland absorbing more water then a non mature wetland. This was the results because the older the wetland will soak more than a non mature one. In the experiment a model of a non mature and mature wetland was made.4 tests ran, 2 for the sponge/mature wetland and 2 for the scouring pad/non mature wetland.

Observations

Sponge
Test1:200ml was poured.The sponge absorbed 75ml.125 is left.
Test2: 400ml was poured.The sponge absorbed 100ml of dirt. 300ml was left.
Scouring Pad
Test1: 200ml was poured.The scouring pad absorbed 10ml of dirt.190 is was left.
Test2:400ml was poured. The scouring pad absorbed 15ml of dirt.
Then that means depending on how mature/old the wetland the more will be absorbed or purified.

Question #1
Rubric #1
1. Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites).
I think that wetlands are important to humans because wetlands are kind of like a filter. When water passes through the wetland, the wetland filters the water by acting like a strainer that filters out toxic chemicals and excess nutrients that can be harmful to the environment and to living things.
Where can we find wetlands? A wetland can be found between the area of dry land and water. For example, let’s say that you live near a lake. You just fertilized your grass, but then it started to rain. Oh, well. You watch from your window and you notice that the fertilizer is dripping towards the lake. That means that the toxic chemicals from the fertilizer could damage the lake, if not, poison it. But there is a wetland between your house and the lake. You watch with amazement as the toxic water passed through the wetlands, and came out to the lake looking cleaner than it did before it passed through the wetland. So the lake won’t be poisoned after all. This is the magic work of wetlands.
The science behind this is that wetlands are full of life. They are home to a very elaborate food chain. There are some insects in the wetlands that feed on bacteria, which is how the wetlands mostly filter the water. Wetlands not only can filter the water of bacteria, but of sediments, too. This helps lessen the impact of erosion.
Since the wetlands can filter out most toxic chemicals, sediments, waste solids, and excess nutrients in the water, the water will be safer to drink. That is the main reason why wetlands are important to humans. Another reason, in my opinion, is that animals drink the same water that we do. If we did not have any wetlands, then the clean water wouldn’t really be an option for animals other than humans. We could simply use our man-made water purifiers to clean the water, but animals can’t. So they will drink the poisoned water, and will get infectious diseases, or die. This animal loss will create a huge impact on humans, so huge that we will have to adapt to a new lifestyle. The reason for this is because we won’t have many animals to eat, and even if we do, we will be diagnosed with diseases because we are eating animals that have those diseases from the unclean water. This is called a food chain. If we can’t eat, we starve.
This is my experiment:
Question: Does the amount of water moved through the wetland affect the purity of the water?
Purpose: The purpose of this experiment is to investigate whether the amount of water moved through the wetland affect the purity of the water.
Hypothesis: I think that the amount of water will not affect the purity of the water.
Materials:
-1000g modeling clay - beaker A (100mL of muddy water) -beaker B (200mL of muddy water)
-beaker C (empty) -beaker D (100mL of muddy water) -model A (my model) -model B (partner’s
model) -roasting pan -scouring pad -microscope -microscope slides -beaker -filter paper
Procedure:
1. Spread the modelling clay in one half of the roasting pan, inclined.
2. Modeled the clay to like “land”.
3. Put scouring pas at the edge of the land of clay.
4. Model A complete. Model B ready, too.
5. Took a sample of muddy water and looked at it trough a microscope and recorded what it looked like.
6. Poured 100mL of muddy water into beaker A.
7. Poured beaker A into model A.
8. Recorded and observed how the muddy water looked at the end of the container.
9. Took a sample of the cleaner water and looked through a microscope to see if it looked any cleaner than at the beginning.
10. Poured 200mL of muddy water in beaker B.
11. Poured beaker B into model B.
12. Recorded and observed how the muddy water looked like at the end of the container.
13. Took a sample of the cleaner water and looked at it trough a microscope to see how cleaner it looked.
14. Recorded and analyzed the observation chart.
Back-up Plan:
1. Took beaker C and put one filter paper onto it.
2. Filled beaker D with 100mL of muddy water.
3. Poured the muddy water bit by bit and let the filter paper filter the dirt.
4. Observed the result and took a sample of the cleaner water.
5. Took sample and used a microscope to record what the cleaner water looked like.
Conclusion: My hypothesis was incorrect. The reason so was because I compared the two samples that I took: sample 1 after the first try, and sample 2 after the second try. Sample 1 looked cleaner than sample 2. Sample 1 was from beaker A (100mL) and sample 2 was from beaker B (200mL). Since sample 1 looked cleaner, my hypothesis was again, incorrect.

Sorry about that Mr. Dobbie. I don't know why the rest of this assignment didn't show up. Here it is.

When I gathered information from my experiment, I realized that the water had looked a little lighter in colour. I then decided to use filter paper to see how much dirt became filtered. The truth was the filtered water from the filter paper looked better and cleaner to drink. The model wetland that I created did work, but I don’t think that the scouring pad was a good fake wetland because it was to light and it kind of started to rise a little bit. So that’s why I used a filter paper instead as my back-up plan.
So, as you can see, the scouring pad was not effective at being a model wetland. My partner and I thought that since the sponge absorbs water, it might ruin our experiment, by absorbing too much water and giving us inaccurate results. We over-estimated the sponge. Next time, I would recommend using the sponge because the sponge is heavier and won’t float away that easily, whereas the scouring pad is lighter and will float away more easily.

Question 2, Rubric 3. What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment? The controls that were required were that don't touch the dirty water, make sure when you put the dirty water in the beaker put towel paper underneath so that the water doesn't spill. I carefully put the water in to the beaker with out my hands touching the water and then I put a paper towel underneath to pervent it fromm spilling.

My wetlands quetion is that does the age of the affect it's abillity to filter pollutants?

Hypotheisis: yes because the more older the wetland the more pollutants it can filter.

Material list:
-scowring pad
-sponge
-tin foil tray
-clay
-dirty water 250ml
-filter paper
-triple beam balance

Procedure:
1. Gatherd materials
2. Make a decline hill of clay using half the tray
3. Make a well at the edge
4.Put sponge where clay ends
5.Meauseredmass of filter paper and recorded
6.Put sample in and measured mass and let it dry
7.Checked how much pollutants were in water record
8.Stirred water than poured slowly
9.Checed how many poullants were in the water
10.Poured the from the tray into a beaker
11.Repeatsteps 1-10 5 times to get an accurate answer
12.Do steps 1-3
13.Put a scowring pad where clay ends
14.Repeated steps4-10and record
15.Then do it again 5 times to get an accurate answer and record

Conclution:

My hypothesis is right because the sponge filtered more than the scowring pad and I meausured them both and found out that the spongs pollutants wighed more than the scowtingpads

Question # 3: Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research.  You must include references (footnotes for websites)

In my opinion, Wetlands are important to wildlife. A wetland habitat is a very important object needed for the survival of threatened or endangered species. Through my research I learned that many fresh water fish are very dependent on wetlands. The fish would feed in the Wetland or the food the wetland provided for them. While I was researching I saw that many fur bearing animals like the muskrat, beaver, otter, mink and racoon prefer Wetlands as habitats. Mostly all of Michigan’s amphibians rely on Wetlands. The Amphibians are sensitive to changes in wetland quality and quantity. Some key factures are wetlands re highly productive ecosystems, and are able to capture energy and provide food for many animals. They provide a natural water balance in the landscape and help to provide protection against floods, so animals homes wont be ruined or damaged


During my experiment I noticed Wetlands were natural filters, so I researched more and found that they are indeed filters. I learned that Wetlands are living filters that remove polluting nutrients and sediments from the surface and ground water. If a Wetland did not filter the water the many different species of animals would die from the pollutants. I find out that Wetlands keep an remove nutrients in four way, uptake by plant life, absorption into sediments, deposition of detritus (organic material), and chemical precipitation.

Rubric #4

Question: Does the amount of water poured into the wetland cause the wetland to lose its ability to cleanse turbid water?

Hypothesis: Yes, I think the wetland will lose its ability to cleanse turbid water

For this experiment, I've found that controls required for my experiment to successfully prove the hypothesis wrong or not would be a controllable wall, a timer and a ditch-like dugout in the clay. In order to keep the control in this experiment, my partner and I had to work together to use the controls in the function. One person wouldn't be able to accomplish the work alone, so we both had a different role; one timed and poured the water, another moved the wall up and down and contolled the dug-out ditches in the immitation. Every time we ran a different method with this experiment, something would go wrong and we'd have to back-track to find the mistake. Thats why contols are manditory and critical. without controls in the experiment, one small thing can go wrong and you wouldn't know where it was in order for you to fix it.

I will hand in my data and observation notes when I get back to school.

question 1:why are wetlands important to the enviorment?

rubric 4

question I experimented:do wetlands clean water?

hypothesis:I am thinking that wetlands do clean water because it is a natural habitat.

procedure:
step 1:gathered all materials

step 2:modeled clay from kit into a slope in the tin foil.

step 3:put sponge at end of slope

step 4:got 100ml dirty water

step 5:got microscope,microscope slides,and cover slips.

step 6:got pipette absorbed dirty water into pipette

step 7: poured dirty water on microscope slide and put cover slip over the dirty water and microscope slide

step 8:put sample onto microscope

step 9:observe and record sample

step 10:took out sample from microscope

step 11:poured 50ml dirty water down the slope in the tin foil

step 12:waited for the dirty water to get through the sponge

step 13:once dirty water got through the sponge absorb the dirty water that came on the other side of the sponge in the pipette.

step 14:record and analyze your dirty water sample

step 15:see the difference beetween the water before going through the wetland(sponge) and after

Observations: I observed that the water before going through the wetland(sponge) is more dirty then the dirty water after going through the wetland. I tested this 3 times to get presice results and the tests told me that the wetland does clean the water. There is more bacteria and germs in the tests that I did when I did not pour the water through the wetland(sponge). When I poured the water through the wetland(sponge) I noticed in my tests that there is less bacteria and germs in it.

conclusion: I noticed that when I did my 3 tests I noticed that a wetland does clean water because the water before going through the wetland is really dirty and the water that went through the wetland is a lot more cleaner and I know that a wet land is a natural habitat that does'nt have too much polution so it does help the enviornment.

2. What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment? Rubric: 3

Question: Does age/maturity of the wetland affect its ability to control flooding?
Experimental Procedure:
1. Gathered all materials.
2. Put the clay on a D-cline scale halfway.Put the clay up to the middle.
3. Put the sponge where the clay ends.
4. This was the model. Poured down the water from where the clay starts.
5. It was done from an angle. Put it on the edge of tinfoil and slowly poured the 250 ml beaker at a set speed.
6. Then took distance (start of d-cline scale to the end of the clay) and divided it by the time it took for the water to reach the end. this gave the speed.
7. Repeated steps 5 and 6 to get more accurate results.

Required controls:
1. water needed to be poured at set speed.
2.The downward slope had to be almost perfectly downward.
3. Pour water properly from the top (the tinfoil) to the bottom (sponge/carpet).
4. Make the clay start at the top of the tinfoil on the one side.

To make sure I maintained the controls, I always poured the water at about a 65 degree angle.For the second control, I took time straightening the clay so it properly was downhill. For the third one, I put the 250ml beaker at the edge of the tinfoil. For the forth one, I started from the top toward to the middle of the tinfoil pan.

These controls were required because if the water is not poured at the speed then every trial is going to be different. If the control is not followed then there will be no accurate result. If the downhill slope is not straight then the water will splash all over the place and that would make the results change as well. The water must be poured properly. The proper way to pour it is from the top(tinfoil). If done any other way the water will shoot of the downward slope. The clay must not start from anywhere else except from the tinfoil. The reason for this is if you start anywhere you want because the slope has to be from the tinfoil to the middle of the pan.

Question 1.
Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)
Rubric # 4
The wetlands are important to us humans because they are maintained in our ecosystem also they are able to capture the energy and provide food for many of our animals in the environment. Another reason is, animals need to have a place to live and eat, and they also prevent flooding by holding the water from it. My last reason is that wetlands are also filter lands that filter water corrupts. But the nature owns the water filter areas.

Question: Does the age/maturity or a wetland affect its ability to filter pollutions?
Purpose: Checking the wetland is pure when a pure water comes threw or to know if the age matter.
Hypothesis: No because inside the wetland water has lots of minerals and other impure things and also the land will be old.
Materials:
1. play do
2. water
3. beaker[150mL]
4. tongs
5. litmus paper
6. microscope
7. sponges
8. tin foul container

Procedure:
1. gathered all materials needed
2.took a gray container
3. defined the clay
4. check the water before & after the experiment with the clay and sponge
4. use microscope to help you
5. observe of the both samples under microscope
6.write what you observe

Conclusion: my hypothesis was correct. It was correct because in my experiment i saw the differences between the two water beakers, one was dirty and a clean one. With my litmus paper we saw the dirty beaker was more purple which means dirtier and the other one was a normal color from the litmus paper. In my conclusion the age/ maturity does matter of the wetland provided.

QUESTION: Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

ANSWER: Wetlands are important to wildlife for many different reasons. One reason would be that, wetlands protect wildife from floods.Also, in their natural condition, wetlands function as a barrier to erosion. The root systems of wetland plants stabilize soil at the water's edge and enhance soil accumulation at the shoreline. Wetland vegetation along shorelines reduces erosion by dampening wave action and slowing current speed.This way, animals will not be extinct. Another reason would be, that they are highly productive ecosystems, and are able to capture energy and provide food for many animals. This is why wetlands are important to wildlife.

MY EXPERIMENT: Does the turbidity of the water change when the water passes through a wetland.

HYPOTHESIS: Yes, the turbidity of the water will decrease when I run the dirty water down the model of the wetland.

MATERIALS LIST:
1) Modeling Clay
2) Timer
3) Roasting Pan
4) Paper Filter
5) Sponge
6) Carpeting

PROCEDURE:
1) Gathered information.
2) Gathered materials.
3) Arranged modeling clay in roasting
pan on a slant.
4) Put sponge at the bottom.
5) Measured mass of paper filter &
recorded.
6) Got a sample of dirty/muddy water.
7) Put it through the paper filter.
8) Let paper filter dry.
9) Measured paper filter again &
recorded.
10) Subtracted mass of the first scale
(ORIDINAL MASS.
11) Ran dirty water down model of
wetand.
12) Filtered the remaining water.
13) Measured paper filter once again &
recorded.
14) Subtracted mass of the first scale
(ORIGINAL MASS.
15) Observed and concluded.

OBSERVATIONS:
Original mass of paper filter is 0.7g
Second mass of paper filter is 0.55g
Third mass of paper filter if 0.53g
*subtracted masses from original mass to get accurate answers.

CONCLUSION: My hypothesis was proved correct. I stated that the turbidity of the water will decrease after it passes through the model of the wetland. The fact is that the turbidity did decrease, according to my observations and calcuations. In addition, yes, the turbidity of the water changes when it passes through a wetland.

Rubric#5
Question#3: Why are wetlands important to wildlife?

:In my opinion, wetlands are very important to humans. The research I had done and my experiment results hold an impact on my opinion. In my research I had found many reasons why wetlands are important. Wetlands can act like a water filter in the environment. There like sponges. Wetlands can act like a filter by removing contaminants from the water. The soil in the wetland holding the plants acts like a sponge, it sops up pollutants. Another reason why wetlands are useful to humans is wetlands increase flood damage. You can also say they slow the flow rate of water. My experiment was based on this. When water passes through the wetlands the flow rate does slow down. This is because the wetland acts like a sponge and does absorb water which can also decrease floods. The last reason I am going to list why wetlands are important are the economic benefits they provide. For example, water supplies, fisheries, agriculture, timber productions, energy resources, wildlife resources and even recreation and tourisms place. Those are all benefits for the economy. As I have said before, my experiment results impact my opinion. I had tested to see whether wetlands slow the flow rate of water. My hypothesis was wetlands to slow the rate of water. In my experiment I had timed how long it took for all the water to pass down the slope without the wetland then did the same experiment but this time with the wetland. There had been a great difference between the times. This led to my conclusions that wetlands do slow down the rate of water. That is why I compared wetlands to sponges because in my experiment I used sponges to represent the wetland.

9. Poured water down slide quickly but not to fast just enough for no other dirty water to splash out of slide
10. Took water that traveled through sponge and measured its mass
11. Subtracted it by beaker mass
12. Took out some tap water so there was a equal amount of tap water to dirty water left
13. Subtracted mass of dirty water by mass of tap water for my answer
14. Did same procedure with scrubber

Observation: My hypothesis is Yes, I do think older wetlands (sponge) filter better than the younger one (scrubber) because in nature usually the older the plant the biger it is. For a wetland the older it is the more plants and vegitation it has and i believe the more vegitation you have the more your wetland wilkl be filtered. I was correct? when I started out, i had a beaker,tap water and dirtyand calculated their mass. The mass of the beaker was 159.3g.The mass of the tap water(175ml) was 331.8g
the mass of the dirty water was 335.3g(175ml)

Then I subtracted the mass of the beaker by the mass of the tap water so the mass of the beaker will not be included in my final answer(13,31.3-159.3=172.5g)then subtract the mass of the beaker by the mass of the dirty water (335.3-159.3=176.0g)now finally subtract the mass of the tap water by the mass of the dirty water (176-172.5=3.5g)and the product will be the amount of dirt and extra components besides the water which is 3.5g.After Idid my procedure with the sponge the amount of extra mass was 1.9g and with the scrubber it was 2.8g

conclusion: to conclude this experiment my extra mass of the dirt from the scrubber was 2.8g and for the sponge it was 1.9g

3. Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

Rubric: #4

In my opinion, wetlands are important to wildlife because wetlands provide clean water to animals by cleaning it themselves. They also provide habitat for animals. Wetlands are not just important to animals but to humans too because it also provides humans with clean water, wetlands reduce flood damage, provide products, and etc. Wetlands have a lot of benefits for humans and animals. Some of the benefits are: reduce flood damage, reduce erosion, Provides habitat, sustainable wetland products, and more. Wetlands promote an overall healthy atmosphere and provide important minerals and nutrients to plants and animals. “One-third of all endangered species resides within wetlands or uses them to provide clean water or food to survive.” The most important benefit for both humans and animals is that wetlands filter water so anyone can drink it. I can prove that wetlands clean water by my experiment.

Wetland: land that has a wet and spongy soil, as a marsh, swamp, or bog.

Reduce erosion: “the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.”


Purpose: Do wetlands clean water?

Hypothesis: I think wetlands do clean water because animals live on wetlands and need water to live.

Materials list:
1. Pan
2. Clay
3. Sponge
4. Cleaning scrubber
5. Dirty water
6. 4 Beakers
7. Filter paper
8. Scale
9. pipette

Procedure:
1. Got a pan
2. Molded clay into a hill in the
pan
3. Put the pan aside
4. Got filter paper
5. Put it on a scale
6. Wrote the measurements down on
the observation chart
7. Got a beaker
8. Put 200ml of dirty water into it
9. Got another beaker
10. Put the filter paper over it
11. Poured dirty water into the
filter paper
12. Waited until it dried
13. Took the filter paper off the
beaker
14. Put the filter paper on the
scale
15. Wrote down the measurements on
the observation chart
16. Got the pan with the molded clay
init
17. Got a sponge
18. Put the sponge beside the molded
clay
19. Poured 200ml of dirty water down
the centre of the pan slowly
20. Got a pipette
21. Got a beaker
22. Beside the sponge there was
nothing
23. The water that did not get
absorbed went to the empty space
24. Put the pipette beside the
sponge where there was empty
space
25. Squeezed the pipette until all
the water that was there was
gone
26. Squeezed the water from the
pipette into a beaker
27. Got filter paper
28. Got another beaker
29. Put the filter paper over the
beaker
30. Poured the water from the other
beaker onto the filter paper
31. Waited until it was dried
32. Put the filter paper on the
scale
33. Wrote down the measurements on
the observation chart
34. Put everything where it was from

Conclusion: My hypothesis was correct. I said that the wetlands do clean water. I performed the test 1 time with the sponge and 1 time with the cleaning scrubber. My results are the following: the test I did with the sponge the water was clean when I filtered it and then when I did my second test with the cleaning scrubber the water was clean when I filtered it. The variable I was testing was if wetlands clean water. Variables I controlled in this experiment were how fast to pour the water, how much water to pour, and How much clay to use. One concept this experiment taught me was that wetlands do clean water. Another concept I learned was how to use filter paper. I also learned how to do answer question by doing a simple experiment. Always remember never eat when conducting an experiment because if your hands are dirty and you touch your lips or touch what you are eating you might get sick and make others sick too.

Question #2
Rubric #3

When conducting an experiment, controls are required. My question for the experiment was, “Does the age/maturity of a wetland affect its ability to reduce flooding?” My hypothesis was that I do think that the age or maturity of a wetland does affect its ability to reduce flooding. The materials I used to conduct this experiment were:
- old sponge
- dish scrubber
- 2 measuring cups
- wetlands kit
- dirty water
- clay
My procedure for this experiment was:
1. Gathered all materials
2. Emptied out science kit
3. Rolled clay around
4. Placed clay on the top of the wetlands kit (without lid) and made it slanted touching the bottom of the kit
5. Made a starting point on the clay where the water was being poured
6. Placed an old sponge at the edge of the clay in the container
7. Poured 200mL of dirty water into the wetlands kit from the starting point
8. Squeezed the sponge into a measuring cup
9. Observed how much water was absorbed
10. Cleaned out the wetlands kit (the dirty water still in it)
11. Got the dish scrubber
12. Placed dish scrubber at the edge of the clay in the wetlands kit
13. Got 200mL of dirty water
14. Poured the dirty water at the same starting point
15. Took dish scrubber out
16. Squeezed it into a measuring cup
17. Observed how much water was absorbed
18. Compared how much water was absorbed from the dish scrubber and the old sponge
19. Determined whether the age/maturity of a wetland affected its ability to reduce flooding

While conducting my experiment I had to make sure that I took some controls. I need to take controls, because if I don’t, my experiment would not be accurate. If it is not accurate then what is the point of the experiment? Also, we need controls to make sure what we do to one thing we do as best as we can the exact same to something else if you are comparing things in your experiment. Some controls I needed to maintain were:
- how the water was poured
- where the water was poured
- how much of the dirty water was dirt
- how much of the dirty water was water
- where the sponge and dish scrubber were located

To keep control of them I had to put my arm in the same position each time while I was pouring the water. The water was poured into a spot I made in the clay each time I conducted the experiment for the dish scrubber and the sponge. When I was pouring 200mL of the dirty water into the measuring cup, I made sure I had 10mL of dirt in the cup and the rest 190mL was the water part. Each time before I poured water into the kit, I put the sponge and dish scrubber right at the edge of the clay and in the center of the edge of the clay. Also, before I poured the water into the wetlands kit, I mixed the water for 10 seconds to make sure the dirt and water were mixed and the dirt would come out with the water.
Some observations I made while conducting my experiment are:
Sponge:
- As soon as I poured some water into the kit it got bigger
- 177mL of water was absorbed out of 200mL
- Of the 177mL of water that was absorbed a little bit of dirt was absorbed
Dish Scrubber:
- It started floating on the water after all of the water was poured in
- Only 2mL of water was absorbed out of 200mL
- When I looked into the measuring cup with the amount of water the dish scrubber absorbed, hardy any dirt was collected, if it was, it was very small and floated around in the water
After conducting my experiment, I proved my hypothesis to be correct. The age/maturity of a wetland does affect its ability to reduce flooding. The older wetland (old sponge) absorbed more precipitation (dirty water) than the more recent wetland (dish scrubber). This experiment can help people find out how old the wetland is. If the wetland is older it would be thicker than a more recently wetland because it would of absorbed more water.

After conducting this experiment I have learned that the age/maturity of a wetland does affect its ability to reduce flooding.

3. Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

Hypothesis:
Yes, the wetland does clean water while it goes by because, since the plants living on the wetland help filter water then the water going through the wetland is being cleaned as it goes by.

Materials:
-Sponge
-Tin foil container
-250ml beaker
-tap water
-Scouring pad
-Funnel
-clay

Procedure:

1)Took tin foil container
2)put sponge in the center (representing mature wetland)
3)put clay on the western corner,creating a hill
4)got a beaker, filled with 125ml of water
5)poured it on the wetland wisely
6)after the liquid has passed down
7)empty the beaker used for this drill
8)put funnel on top of the beaker
9)poured in the water left inside the container
10)collected data how much is inside
11)subtract that by how much is absorbed by the sponge
12) collected data after subtracting
13)the data gotten is how much the sponge (mature wetland) absorbed out of how much poured in
14)do same drill with scouring pad (young wetland) and campare them together for conclusion

Results/Conclusion:

Before starting the experiment, i had researched and on this site http://www.ducks.ca/resource/general/wetland/wetlands.html i have learned that wetlands are natural filters and the plants/animals living on it help filter harmful impurities (something that is or makes impure). I also learned what wetlands really are and how they work from http://www.ducks.ca/resource/general/wetland/work1.html.
When i began my experiment i represent the sponge and scouring pad different. Scouring pad represents Young wetland as for Sponge it represents Mature wetland.With that i carried on and followed the procedure.when i collected data, i noticed that the Sponge (Mature wetland) absored more than half of amount poured stating that mature wetland cleans alot of water, but still i cant say that for sure because i did not try the scoruing pad yet. Now this time i am going to run the same drill with the scouring pad to see if young wetland cleans (absorbs) any water. after i had ran the experiment i had collected data and noticed that the young wetland (Scouring pad) barely cleaned (absorbed) any water. i poured 125ml again and after i subtracted, how much was left inside the container. There was 115ml left, leaving behind 10ml of water being absorbed(cleaned) meaning that Mature wetland cleans water while young wetland is still growing. Since from my calculations, my collected data states that the sponge filtered 75ml of water where the scouring pad only filtered 10ml, so the Mature wetland cleaned a lot more than the young wetland. Which leaves us to the final question, Why are wetlands importent to wildlife.Wetlands are importent to wildlife is because of many reasons. firstly it filters water NATURALLY. Secondly it is a habitat (home) to many living animals and plants, also because this helps is balance nature because alot of gases and other harmful substance have been in water and sometimes we dont clean it properly making us capable of catching a disease, and now that wetlands clean water we dont have to double check if it clean because wetlands are spread out throught-out the world. Wetlands should be protected, they are not just free space that we can use to build houses on. wetlands are very importent and if you still need more information on why you can research on my reference websites.

Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)


1. The first way wetlands are important is they act as giant sponges to reduce flood damage. When flooding occurs they soak up the water slowing the flow rate of the water and they release the water slowly. This helps reduce erosion along the coasts of the wetlands. If the wetlands don’t act like as giants sponges there is going to be a lot of consequences.
-The flood water will flow on to the land and it’ll damage the plants and animals that live there.
-It could flow into neighborhoods and could cause damage there.
-It could flow into sewers and could affect the purity of the water
-It could flow onto ecosystems and it could damage the ecosystem
-The coastlines will be damaged by the water. Erosion will occur along the edge of the wetland
2. The second way wetlands are important they purify the water so basically they filter out the excess nutrients in the water. As the water passes through the wetland, the plants purify the water as it passes through. Animals depend on the river to get fresh drinking water. When the plants purify the water they remove mercury, lead, fertilizer, and bacteria that causes diseases, etc. If the water wasn’t purified by the plants there are a lot of consequences to be faced.
- The chemicals would pollute rivers and dams because there is nothing to purify them.
-The animals will die or become sick drinking the water which will affect the food chain. The other animals on top of the food chain will die eating the poisonous animals.
- We’ll lose a lot of animal species. A lot of animal species live in the wetlands. - People will die of drinking the dirty water. Dirty water will contain poisonous stuff which will kill the person
- People won’t be able to grow rice. A lot of people depend on rice.

3. The third reason wetlands are important is they absorb greenhouse gases. Humans burn a lot of fossil fuel and wetlands absorb all the greenhouse gases. If people drained every wetland or if wetlands didn’t absorb greenhouse gases, there is going to be a big consequence.
- Global Warming is going speed up very fast because humans don’t have anything to absorb the greenhouse gases. More droughts will occur, the temperatures in the ocean will rise faster, more animals will die, the temperature is going to increase quicker, and the ice in the arctic is going to melt faster
- If plants are destroyed the gases will be released and big carbon bomb is going to occur. What this means is the emissions will spread faster because there is nothing to absorb the gases
-
4. The fourth reason wetlands are important is they regulate the climate for an entire region. This means they provide rain at the right time in right amounts and the plants control the amount of water to fall not too much not too little. If plants weren’t there to control the climate the negative consequences will be
- Flooding or droughts could too much rain could fall too little rain could fall.
- If too much rain fell animals could die because their food will be destroyed by the water, the land will be damaged, and plants could die because the soil could wash away and they have nothing to support to
- If too little water the animals will die because they won’t have enough water to drink, the land will become dry because they don’t have enough to be healthy, and the plants will die because they don’t have enough water to live.

5. The next reason wetlands are important is rice can be grown. Over half of the world’s people depend on rice to eat. People grow rice on wetlands. They do this by making rice paddies. Rice paddies are flooded puddles of land to grow to rice. Rice Paddies are also important habitats to animals. Rice Patties are artificial wetlands. If Rice paddies weren’t built the negative consequences will be
- There won’t be enough rice for everyone in the world. That’s bad because a lot of people depend on rice.
- Farmers won’t be able to make any money
- Some animals won’t have homes. They depend on rice patties to have a habitat.


6. The second last reason wetlands are important is people do certain activities. These activities include bird watching, fishing, boating, bird watching, photography. The tourism industry earns a lot of money from these activities. Wetlands can also be used

Sorry about that some reason the other half didn't appear
6. The second last reason wetlands are important is people do certain activities. These activities include bird watching, fishing, boating, bird watching, photography. The tourism industry earns a lot of money from these activities. Wetlands can also be used for transportation. People can just travel across the wet land using an air boat to find a good fishing spot, to take a tour of the wetland, find a good area to take pictures of the animals. If people destroyed the wetlands the consequences will be
- The industry will lose billions of money causing an economic crisis
- They can’t take a tour of the wetland
- The fishing spots will be gone. Some people like to fish in wetlands.
- People can’t take pictures of the animals. Some people like to take pictures of animals
-More Carbon Dioxide will be released in the air because people will be traveling to something fun/entertaining. If the wetlands were there people could just go there to do something fun/ entertaining and plus they’ll understand why wetlands are important. If they go to an amusement park they won’t learn a single thing.



7. The final reason wetlands are important to humans is that certain plants found in wetlands have some good benefits such as Butterbur can cure headaches, fevers, and colds. Horseradish can calm a toothache. Sphagnum moss can hold a lot of liquid and fights bacteria so it’s good for cuts, scrapes, and other wounds. Recently it has been used to clean up oil spills. If these plants were destroyed this is the consequences
- People that can’t afford to buy drug will die of their condition. The reason is they don’t have anything to cure their condition because they’re too poor to afford the drugs.
- Oil spill affects will be much worse because people use sphagnum moss to clean up oil spills right. So if sphagnum moss was destroyed and oil spill occurred their going to have to call in a boomer to clean up a oil spill and that is going to take some time and oils spill is going to spill in a larger area but that wouldn’t have happened if they had sphagnum moss.

Question: does the volume of water affect flow rate of water through a mature wetland?

QUESTION: Why are wetlands important to humans? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)





Wetlands are essential for humans for many various reasons such as:

- Wetlands could be used as an environment for animals and also humans

- Reduce erosion

- Improve and maintain good water quality

- Ensure a stale, long term supply of ground water

- Provide recreational and tourism opportunities

- Provide valuable economic products such as timbre commercial, baitfish, wild rice, and natural medicines

Also if wetlands decreased the rate of water then there wouldn’t be a lot of flood damage happening. I know this because I did an experiment which involved testing out to see if a wetland really did decrease the flow of water. The steps I did were

My procedure was :

1. Collected materials

2. Got pan

3. Measured the distance from the slope to the rim

4. Put clay on right side of pan, bottom looked like a slope

5. Got timer

6. Poured water from top of slope, recorded how much time it took to make it down slope

7. Repeated step 6 two more times

8. Cleaned out pan

9. Repeated step 4

10. Repeated step 5

11. Used sponge, made a wetland

12. Put sponge in the middle of pan beside slope

13. Repeated step 6

14. Calculated speed, divided distance and time

15. Compared results and saw whether or not wetlands decreased the rate of water



These steps include how I first took the wetland and poured water from the top of the slope and timed the water going down the slope I stopped the timer when all of the water was soaked in the sponge(a wetland). After i calculated the speed of the water I did the experiment again 3 times to make sure my answer was accurate and it was because the speed showed up to be almost the same each time. After i had to see what the speed of the water was without the wetland (sponge) so I did that experiment and again to make sure my answer was accurate i did it again three times. I noticed that most of the water that was poured was being sucked into the sponge which is displaying as a wetland. Only some of the water got across to the other side of the pan. When I calculated the speed of the water going down the rim and into the sponge ( wetland) I noticed that it took longer for all of the water to soak into the wetland and it didn’t take as much time without the wetland.







Some of the websites i used were:

www.epa.gov/owow/wetlands/pdf/flooding.pdf

From that website I got information on how wetlands can decrease flood damage

3. Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)
PLEASE MARK ME ON RUBRIC 4

First of all, I'll start by explaining what a wetland is. Wetlands are important for our environment, they provide benefits to humans and animals. A wetland is an area of land that is wet permanently or seasonally. Some types of wetlands are swamps, marshes, and bogs. Wetlands are biologically diverse ecosystems. They include, plant life and animal life.

Also, i will explain what wildlife is. Wildlife includes every non-domesticated plants animals and oganism, so when i type animal or plants or organisms, i mean wildlife. So, if it is beneficial/important to non-domesticated plants, animals, or organisms, it is beneficial/important to wildlife.

My procedure:
1) Placed the model on the counter
2)Set up sample. Molded the clay into a land, the land was set at an angle going downwards.
3)Made a slope and marked a spot on the slope.
4)Placed the wetland(Old or new) in front of the slope(land).
5)Prepared speed chart(Drew 5 sections, numbered try, time it reached the end, and density before and after).
6)Calculated density of the water before pouring the water(By mass of water with beaker subtracted by mass of beaker, to find mass of water. Divide mass of water by volume of the water in the beaker. Density=Mass divided by Volume)
7)Wrote down density under the "Density Before" section.
8) Measured the distance from the marking spot to the end(reaching point).
9)Wrote down the distance from marking point to end.
10)Poured water on marked spot at a fixed speed(fixed angle) and started the timer at the same time.
11)Stopped the timer when the water reached the end.
12)Wrote down how much water past(By volume),speed.
13)Calculated speed by distance divided by time.
14)Calculated the density after the water passed through.
15)Repeated steps 10-14 with number of results desired.
16)Repeated steps 10-15 with another type of wetland.
17)Wrote down all the data and compared.

Results
What i noticed is, wetlands affects the quality of the water and blocks and absorbs some of the water. The speed was about between 3.09cm/s to 3.53cm/s for the blue wetland(New). cm/s= centimeters per seconds, fits in because the distance is about 16 cm and it only took seconds to reach the end. The old wetland was 2.11cm/s to 2.62cm/s. Next, i calculated density, i noticed that the density decreases every time i try it. The density is usually around 1-1.4 and sometimes nine, but after it passes through, the density decrease, it was about 0.7- 0.96. That brought up another question, how does this happen. I thought that the sponge traps some of the solids when passing through, liquids could get through because they are very tiny and can change shape, the small holes allowed some water through, and trapped some water and solids. Then, i researched online, in wetlands,there are sediments and organisms that live in wetlands, they trap, breakdown or absorb these nutrients.Up to 92% of phosphorus and 95% of nitrogen can be removed by passing through a wetland. There are also other organisms that live in wetlands, insects eat up the bacteria therefore, removing it from the water. Wetlands can also trap sediments!

Density= Quality of water
Also, what gets absorbed by the sponge could represent the groundwater of a wetland. Like trapped water. If density lowers, it represents the natural filtration process of a wetland.

This means animals can have a clean fresh source of water because of the natural filtering system and because, wetlands are wet either permanently or seasonally. Wetlands are biologically diverse, lots of living things lives there, such as plants and animals. Plants can also be a source of food for animals, and animals can also eat each other(such as bears eat fishes). My research shows that wetlands reduce density(Density determines the quality of the water and the speed it moves in). Reduced density means cleaner water, which benefits animals and possibly humans. I also proved that wetlands reduce flood damage. My wetlands, new and old, absorbed and delayed the water. The wetland blocked the path and absorbed the water while blocking the path. In reality, wetlands store water. When there is a flood, wetlands store excess water to prevent flooding. This benefits the animals because flooding can cause animals to drown and die or even get cold. As it stores excess water, it releases it back into the environment and seeps back, therefore filtering it and providing a good source of clean water for animals.The ground water recharges and discharges which ensures a long-term supply of clean water for animals. They also prevent soil erosion helping plants and then, plants get eaten by animals. They are also an essential habitat for a

My other half was cut off.

They are also an essential habitat for as many as

600+ species in Canada! This means wetlands provide a home and this benefits those animals, plants, and insects. Wetlands can

also remove greenhouse gases, which are very harmful. Removing them benefits humans and animals! Many species of fishes live

in the waters, providing food for other animals.

Summary
Wetlands are benefits animals and humans!
-It reduces erosion
-Decrease flooding and flood damage
-Improve and maintain clean, fresh water for animals and humans
-Naturally filters the water without using electricity
-Provides long-term supply of clean, fresh water by recharging and discharging(Naturally filtered)
-It helps limit and prevent harmful greenhouse gasses.
-Many species live there, over 600 species live in wetlands
-Many fishes and plants, providing another source of food for animals
-Lots of rare species
-Provides a habitat for many animals, plants and insects

All of these points are beneficial animals. Reduced erosion equals more room, more plants, more plants and food for animals

to eat. Less flooding and damage equals, less hurt animals, less drowned and wet animals, protection from floods(including

the area).
Clean, fresh water equals a healthy animal and no diseases from the water. Natural filter is benefitial because it doesn't

use electrity, which wastes non-renewable resources sometimes, such as coal which causes pollution. Natural filters equals no

waste of electricity, no use of non-renewable resources equals, no loss such as consumed resources and pollution, equals

benefits for the world. It also provides clean water for drinking uses. Long-term supply of water equals more water for

animals, less thirst and less deaths from dehydration. Less greenhouse gases is harmful as it is. If it could be lowered, it

benefits the whole world. It is the cause of global warming(I think), the gases increase temperature than above normal. Being

too hot or cold is not good. Eating too much or less is not good. That is why greenhouse gases are bad and reducing them

benefits the whole world. More species, more choices for what animals get to eat. A habitat is very important. A habitat is a

home, wetlands could be habitats, providing home for animals. With a home, they could live and learn their way around. It

benefits them.

So in conclusion, wetlands benefits wildlife. There are many benefits which makes wetlands important to not only animals, but

the whole world! This is why wetlands are important to wildlife.

3. Why are wetlands important to wildlife? Be sure to answer the question using proof from your experiment and from your research. You must include references (footnotes for websites)

Mr.dobbie the video on my website is almost up so check back as much as you can but here is my answer

http://www.hillsdalecounty.info/planningeduc0011.asp

Wetlands are important to wildlife because they provide food, shelter and more to animals. it is critical for endangered species for their survival and most animals that are rare or almost endagered are found mainly on wetlands.

Wetlands provide also a large home to many different species of fish because the water there is fresh and they can feed on food there. From my research and experiment i did find out that the wetlands are natural filers and they filter out dirty water as they mature. There are also other creatures living there like birds live there and they live just like fish, they can also use the wetland to protect themselves against predators by hiding over big trees. Wetlands DID YOU KNOW? wetlands provide home to over 600+ species?! also did u know that there are muskrat, beaver, otter, mink and raccoon living in wetlands too?

Overall wetlands are important to both human and animal survival

2. What controls were required during your experiment? What did you do during your experiment to make sure your controls were maintained? Why are controls required for this experiment?
i would like to be marked by rubric#4 please.

here are some controls that were kept during my expriment:
1. molding clay around the sponge.
molding clay around the sponge was nessesary because there were areas around the sponge that had an opening that the dity waster could have gone through. this would have made my results inaccurate because when i would have measured the mass of the particulate later on, it would have efected it.

2. sturing or mixing the water before it was poured down the clay slpoe.
i had stured the dirty water before pouring it down the slope because all the particulant was at the bottom of the beaker and to make it like as real as possible.

3. wetting the sponge before using it as a wetland.
this was done because like in real life, wetlands aren't dry, thus the name wetlands. this was alos done to make this experiment as real as possible.

this is my experimental procedure:
DOES THE AMOUNT OF WATER MOVED THROUGH THE WETLAND AFFECT THE PRUTIY OF THE WATER?

1. gathered all materials
2. used modeling clay to make a slpoe in pan
3. measured mass of filter paper and recorded it in observstion charts
4. measured 90ml of water into a gradulated cylinder
5. poured all water into filter paper
6. waited untill particulant dried up
7. measured its mass on scale
8. placed sponge next to slope
9. measured another smaple of 90ml of water
10. poured it down the slope
11. used a paper filter again to filter the water on the other side of the pan
12. repeated steps 5 and 6
13. recorded observations
14. measured a smaller amount of water\(50ml)
15. repeated setps 3 to 13.
