Please choose only 1 question from the list below to complete after you've finished your experiment related to personal water usage.  You must include research collected from your experiment in your blog response.
1. What have you learned about how you consume water? 
2. Which consumption strategies could be the most effective at reducing water usage? Why?
3. How could your results be used to help other Canadians?
4. Do car washes use less water than washing a car by hand?  Prove your point.
5. How did you control your experiment to make sure your results were as accurate as possible?

Why is tap water clear and pond water is not?  What makes pond water so colourful?  How do humans remove all the colour?  Why do humans remove all the colour from pond water before we drink it?.....Did you ever drink water from a pond?  Why or why not?

Why do people need scientific notation?  Isn't it just a waste of time?  Give a real-life example of how it is used in every day life.  What professions use this number sense tool? Why?

After observing the relative amount of available surface fresh water on the planet, do you believe it is necessary to conserve the amount of water we use on a daily basis? (keep in mind we live in Canada and have more water than we need;)  Please explain why you believe what you do.

As we learned in class today, we don't have to write out the factor lists for numbers and then compare them when trying to find the Greatest Common Factor of 2 numbers.
What technique could you use to find the GCF when comparing 2 numbers?  Could you give an example?  (hint: you could write an example, take a picture of your work, then post it as part of your blog if you want)

Hopefully you've had a chance to think more about the current world water crisis.  I know it doesn't really hit home because Canada has so much fresh water but shouldn't we be sharing our water with other countries?  Would it be fair to charge other countries for our water if we share it?  Is water a human right or a paid privilege?  What do you think?

How do you know if a number is really prime?
