Rain Gardens Stormwater Curriculum: Tahoma School District, 3rd Grade

The purpose of this five lesson unit is to educate grade three students that they can make a difference by decreasing stormwater pollution on their school grounds and in their own neighborhoods. Students learn about stormwater and how it carries pollutants to our surface water such as lakes, streams and the Puget Sound. They explore concepts of filtration, pervious and impervious surfaces, and water flow on their school campuses.
