Should Chlorine Be Banned from the Great Lakes?
A classroom debate allows students to visualize a complex issue from many different perspectives, describe the legislative process, its functionaries (agencies, individuals involved in creating legislation), and the time involved in creating environmental legislation, and appreciate the difficulties in consensus-building in environmental disputes.
Where do all the toxins go?
When students have completed this activity, they will be able to demonstrate how chemicals accumulate in fish fat, the biopathways of the toxins in the fish’s body, and ways to prepare fish to avoid consuming the toxins.
How Big is a Crowd?
In this teacher-facilitated activity, learners will construct the five Great Lakes from string and use wrapped candy or peanuts in shells to investigate the impacts of population centers on Great Lakes fish
production and water quality. Students learn to compare the relative sizes of the five Great Lakes and their human populations, as well as describe some of the problems that arise when many people
depend on a limited resource.
Students learn about bacteria as an indicator of beach water quality for swimming. In groups they solve
hypothetical problems associated with beaches. Then students write persuasive essays on the issue.
Hydropoly: A Decision Making Game
Students play a board game to hone their decision-making skills. Through the various choices posed in the game, they are asked to consider both economic and environmental well being in making decisions.
What Are the Characteristics of the Great Lakes Exotic Species?
This puzzle activity is designed to help students review facts and information about the characteristics of the Great Lakes exotic species. They also learn about origin and introduction methods.
What are some characteristics of Great Lakes fish?
If you know how to construct a dichotomous key, you can make one that classifies real organisms, some fish in the Great Lakes. After building a dichotomous key, students will describe some ways fish differ from each other in appearance and use similar characteristics of fish to group them into categories for classification.
Who Can Harvest a Walleye?
Students play a board game where they learn the meaning of the following terms as they relate to a
biomass pyramid: producer, herbivore, first-order carnivore, second-order carnivore; calculate the relative number of kilograms at each level of the biomass pyramid in a given environment; and analyze how different conditions in the environment affect the pyramid.
Students study Creature Cards at sand dune ecosystem stations and determine what adaptations help the organisms to live in their environments.
Rival for Survival
This game presents real-life choices involving exotic species found in the Great Lakes, such as zebra mussels and purple loosestrife. Students are to analyze a situation related to ecology and make an environmentally sound decision. After playing the game, students organize what they learned into a concept map.
