Biofilms and Biodiversity
This interactive lesson introduces students to issues of biodiversity in Chesapeake Bay. It features background information, as well as directions on how to conduct biofilm experiments using plexiglass discs or CDs to culture communities in your local body of water. The experiments demonstrate how water quality, depth, and biodiversity are linked. For students whose school is not near the original site, data and images from the original experiments are available for analysis.
