This lesson is designed to introduce students to impacts of human activity on the health of watersheds. Both point source and non-point source pollution will be investigated and used to evaluate the health of the Chesapeake Bay and the James River. Finally, students will be asked to consider ways the human impact can be modified to improve water quality and bivalve habitat.

Once students have generated a conclusion, they should work in small groups or as a class to brainstorm and evaluate solutions, and then take action! Throughout this process, teachers play an important facilitation role by forming groups, moderating, and answering questions, while students drive the decision-making, planning, and implementation in an age-appropriate way.
