1 Water, water … everywhere?

2 Using the measuring cup, take out 4
Using the measuring cup, take out 4.5 cups from the buckets and pour them into the pitcher. You have now divided the world’s water into fresh and salt water. Can you guess which is the fresh?

3 Using the measuring cup, take 1 cup out of the fresh water.
The 3.5 cups remaining in the pitcher represents the water unavailable to us because it is tied up in: glaciers ice caps Icebergs and the atmosphere.

4 In the 1 cup of freshwater, some of this water is so deep in ground water that we cannot get to it, or it is water in places where no one lives, or it has been polluted. However… there is some water we can use 

5 Take an eye dropper and use it to place 10 drops into the small glass.
THIS is the fresh, unpolluted water in the world that over 7 billion people have to use! 2 of those drops represent the Great Lakes.

6 There is a lot of water in the world, BUT…
97% of it is in the oceans (salty!) 2% is locked in glaciers Leaving only 1% for all of the land based plants, animals, and over 7 billion (and growing) humans to survive on!

8 Canada is home to how much of the world’s fresh water supply?
20% 1 out of every 3 Canadians rely on the Great Lakes for their water More than 3 billion litres of untreated sewage is dumped into our waterways every year by 21 cities across Canada Less than 3% of the water produced at a large municipal water treatment plants is used for drinking

9 Human Activities … Food for Thought
It requires 10 litres of water to manufacture 1 litre of gasoline It requires 300 litres of water to produce 1 kilogram of paper It requires 1000 litres of water to grow 1 kilogram of potatoes The average Canadian home owner doubles their daily water use in the summer months in pursuit of a lush, ‘green’ lawn

11 Which country do you think is the largest consumer of water?
#1 United States – 425 litres / day #2 Canada – 330 litres / day #3 United Kingdom – 200 litres / day #4 France – 135 litres / day #5 Israel – 135 litres / day Rural India – 35 litres / day

12 Many people in the world view water as a resource more valuable than gold …

16 A RIVER PUZZLE Every river has a beginning and an end, but a lot of different things can go on in between! The things we do can affect the health of our rivers.

17 YOUR CHALLENGE: TO MAKE A HEALTHY RIVER THAT EVERYONE CAN LIVE WITH FOR A LONG, LONG TIME! Cut out the puzzle pieces. Put the source piece at the top. Put the mouth piece near the bottom. Sort the other pieces into categories: nature, urban, agriculture, industry, recreation, power

18 THINGS TO CONSIDER: What can happen to a river when a factory is nearby? What can happen when a town is close to a river? Where along a river would water be clean for swimming or fishing? Does farming affect the water in a river?
