Explanation

If you forget to water a plant, its leaves droop. People need water too, but we cannot see it as easily. Your body is mostly water. Water keeps your temperature steady, helps your joints move, cushions your bones, and helps carry waste out of your body. Every day you lose water when you sweat, when you go to the toilet and even when you breathe. You need to drink to replace it. If you do not drink enough, you may feel thirsty, tired, dizzy or get a headache. Tell a grown-up if you feel this. Water is the best drink for staying hydrated; milk is good too. Very sweet drinks are only for sometimes. On hot days and after playing, you need more cups of water than usual. A water tracker helps: colour one cup for each cup you drink.

Class activity

Water tracker and poster. For five days, draw a row of cups each day and colour one cup each time you drink water. Count your cups. Then make a poster that teaches other children why water matters: a title, one fact and a picture. Choose one idea and practise telling it to your class.
