In order to understand many important water-related issues, students need to understand the existence and dynamics of watersheds (a.k.a. drainage basins). This "Island Watershed Activity" will help them realize how an abandoned mine can cause the presence of dissolved metals in a stream many miles from the mine site, and how farming practices in the Midwest can contribute to a "dead zone" in the Gulf of Mexico.
CLICK HERE to read about the details and print a student handout. The activity takes the better part of three class periods to complete (50-minute periods).
