Chesapeake Bay Watershed, Structure & Function of Aquatic Organisms
Overview: Students will analyze maps of the Chesapeake Bay Watershed and create a watershed model to develop an understanding of what a watershed is and gain information about impacts of natural Earth processes and humans on the watershed. Students will take a closer look at the aquatic organisms that live in the Chesapeake Bay Watershed and how their structures and functions help them survive in their environment.
