"This week is Science Week and we went for a talk in the library. The talk was about how we could save water. Some of the ideas were as follows:
Use a bucket of water to wash your car instead of a hose, insulate your pipes instead of keeping a drip going to prevent a pipe freezing, wash your dog in the river ( but don’t use shampoo of course!), wash the vegetables in a basin of water instead of using a running tap and to use rain water to water plants.
The earth is 71% water but 97.5% is salt water wich leaves only 2.5% of clean water. Some of the clean water is locked away in glaciers so only 1% of the water is safe and available to drink. An average person uses up to 150l of water each day!
There are four parts to the water cycle.
1. Evaporation (where the water rises).
2. Condensation (where the water forms clounds).
3. Precipitation (where it rains, snows or hailstones fall).
4. Run-off (where the rain falls into rivers and lakes)."
