GBC Unit 3 - Water and the Built Environment

Students learn about the key issues related to water use and consumption, including pollution, competition, overuse, and waste. They also learn how conservation and resource protection can address these issues. Finally, they examine strategies, technologies, and policies that help achieve more sustainable water use and consumption. The hands-on audit asks students to evaluate their school’s water use and consumption by inventorying all of the indoor water fixtures. They calculate how much water their school would use if each fixture was used once (e.g., toilet flush) or was run for one minute (e.g., faucet, dishwasher), and then predict actual water use. They compare their predictions to the school’s water bills, and bring these ideas home in a household water audit.
