STC Program: Ecosystems, 2nd Edition
This unit focuses on a much larger ecosystem-the Chesapeake Bay watershed. You'll discuss the bay's complex problems, including pollution and population challenges, and students will discover that in a large ecosystem, as in their columns, altering one resource can impact others.
