STC Program: Ecosystems Unit Kit, 3rd Edition
In Ecosystems, students set up terrariums for crickets and isopods. Duckweed, algae, Elodea, guppies, and snails are introduced to an aquarium. Connecting the 2 habitats to create an "ecocolumn," students observe the relationship between the 2 environments and the organisms living within them. Students simulate the effects of pollutants -road salt, fertilizer, and acid rain - on the environment.
