Twelfth graders examine Earth’s precious freshwater — how little of it is available, how it becomes polluted through eutrophication and point and non-point sources, and why protecting water is one of the great environmental challenges.
Students will be able to…
Earth is the “blue planet,” yet clean, usable freshwater is astonishingly scarce — and easily polluted. How much freshwater is really available, and how do we protect it?
Project each item and have students answer about water resources and pollution. The tool explains scarcity, eutrophication, and pollution sources.
