Mercury in Foodwebs
In the Introductory Unit we introduced students to mercury. They learned that it is toxic and they should, also, have at least a rough idea of the kinds of quantities that we might expect to find in human hair and in fish. They should also have a general familiarity with the way that mercury, in its different forms, moves through the environment; more specifically they should think about how it moves through their study site and organisms. Students using the activities in this unit will diagram the mercury cycle- as it pertains to their research site, and can develop a general understanding of toxicology and can play the Food Chain Game.
