Chesapeake Bay

Activity 9 (Explain): Modeling Pollution in the

Chesapeake Bay

Expand All

Collapse All

Switch to Dark Mode


Activity Summary

In this activity, students begin the challenging task of developing a model showing how pollution gets into the Chesapeake Bay. They work collaboratively to come up with a list of what belongs in the model, and then they assemble the model together as a class.

A Note About Timing for This Activity: The Chesapeake Bay pollution model can get rather complex. As such, you may want to build it slowly throughout the course of the module as opposed to waiting until this point. Either way, students will need support building the model, so be sure to consider ways to scaffold the model-building however you choose to implement it.
