Tracking toxins

In this activity, students model bioaccumulation of toxins in marine animals. They participate in a food web game where feeding decisions determine their survival.

By the end of this activity, students should be able to:

• explain bioaccumulation of toxins in a marine food web

• explain harmful algal blooms (HABs)

• explain what scientists are doing to help keep us safe from marine toxins.
