In this lesson, students study the availability of water on Earth and discuss methods that can be used to purify and conserve this critical resource. Using multimedia interactives, video, and classroom activities, they will identify sources of fresh water available for consumption, understand the need for water conservation, and compare the benefits and drawbacks of different water management techniques. They will also assess how much water they and their families typically use, and think about ways to reduce their water usage. Finally, students explore different techniques being employed for water management around the world, including the use of dams to create reservoirs.
