Pollution in the Anacostia River

Seventh graders are introduced to Earth day--- what is it and why do we care, ease into topic of pollution, where have they seen pollution in their community, steer conversation in the direction of the Anacostia. They are reintroduced Anacostia in the first few minutes, 7th graders are reminded of the previous day's discussion on pollution in the river. Students sort through *fake* river pollution and choose an item to talk about.
