1. Guess how many litres of water your house uses each day. Ask your parents to show you four
water bills across four seasons. How much water does your house use per day? Explain why you
might use more water in different seasons. How many litres of water does each person in
your household use each day?
2. Write a paragraph describing how you could restrict your water usage to just 50 litres each day.
Would it be possible? Be creative in thinking of ideas which don't harm your health (that is, you
have to brush your teeth every day and wash your hands after going to the toilet).
