Rain Gardens to the Rescue

Students will measure the impervious area on campus, including the school building and paved surfaces, in order to calculate the size of a rain garden large enough to filter the “first flush” of runoff from a rainstorm; then observe the flow of runoff on school property and determine locations where a rain garden should be located in order to filter water before it enters ditches, creeks or storm drains; design a rain garden, and install it.

Concepts: Erosion | Precipitation

Essential Questions

  • How can I design and build a rain garden that will filter contaminants and pollutants from run-off water on school grounds?
