Think about ways we use water daily, build a rain gauge, find out how much fresh water is on Earth, and make posters to encourage others to conserve.
Water is essential to all living things and it cycles through the environment.
Students will be able to:
Search for clues about how we use water at school and at home.
Rain, snow, rivers and oceans – there’s a lot of water in the world. Or is there?
In British Columbia, we use about 300 litres of water per person per day (Statistics Canada, 2013). We use water every day to drink, flush our toilets, brush our teeth, run our baths, grow and cook our food, wash our dishes and clothes, and make our electricity. Our province has a lot of surface water in lakes and rivers, but despite this, only one per cent of water on Earth is readily accessible. When students understand how they use water, they can explore ways to reduce their water use.
Water is important to all living things, including plants and animals. Living things depend on water for food, drinking, habitat and more. For humans, water is also used for things like washing, farming and generating electricity. Water comes from five main sources.
Water covers almost 80 per cent of Earth’s surface, but there is only a limited amount of fresh water available to living things, including humans.
The activities in this lesson provide an opportunity to assess individual students and small groups on their ability to:
