PCBs in Hudson River Fish

Grades: 
9-12
6-8

The Hudson River has one of the highest levels of PCB pollution of any river on the East Coast. In this module, students will learn about the history of PCB's in the Hudson, how PCB's get into the fish we eat, and what has been done to remove PCB's from the Hudson River. Students will also gain experience analyzing data by exploring how levels of PCB's vary over time, location, and between different species of fish. There are separate versions of the lessons that are appropriate for middle school and high school students.
