Activity Summary

In this activity, students learn about the two major forms of nitrogen pollution in the Chesapeake Bay airshed: nitrate and ammonium. They interpret maps to understand how nitrate and ammonium pollution have changed over time, and they read about the two pollutants in order to compare and contrast them. Finally, students add to their Chesapeake Bay Pollution model and identify sources of nitrogen pollution in their communities.
