Activity: Water Footprints
Students try to calculate the amount of water they use in a day, a week, or a year. They try to think of all ways that they use water and come up with a way to estimate their total.
Each student then gets a card that either lists a way we use water, or has a volume in litres. The students take turn reading their cards and the other students respond by reading their own card if they think it provides the answer. After completing the activity, the students can re-evaluate their estimates for their own water usage. This can be followed up with a discussion or brainstorm on how we can reduce our water usage.
