Lesson plan with video, grades 6–8

Description

Nature works to filter water and to release water over time, thereby reducing the amount of artificial treatment needed to filter water and helping to prevent flooding. In this lesson, students learn about the importance of water quality for human health and agriculture. They relate their own consumption activities to the water supply and also brainstorm various threats to the water supply. By contrasting natural filters with impervious (paved) areas, students compare the impact of development on the ability of nature to provide clean freshwater.
