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.
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 is the Great Lakes Triangle?
Analyzing multiple sets of data, students learn to demonstrate an ability to perceive patterns in a set of data, explain how scientific habits of mind should include the seeking of logical explanations for “mysterious” happenings.
Where Should I Relocate in the Great Lakes Region?
This activity will allow students to describe the Great Lakes region using a map and identify some of the resources the region has to offer. Also, by using maps and graphs students can demonstrate how they can provide information for decision making. Students will describe a decision making process by which people can evaluate a geographic area as a possible home site.

How long does it take water to flow through the Great Lakes basin?
Water that is in a lake does not stay in that lake. Where does the water go? The length of time that it takes for the amount of water in a lake to be completely replaced (enter the lake) is called retention time. Each of the Great Lakes has a different retention time. Construct an appropriate model of the water flow of the Great Lakes learn about retention time and replacement time, and how how Lake Superior affects the dynamics of water flow, retention time and flushing rates for the Great Lakes system.
How does water move in the Great Lakes basin?
You are familiar with the water cycle. The sun heats the surface of the earth, water evaporates, water vapor rises in the atmosphere cools and condenses, precipitation falls and then water flows in the streams, rivers, lakes and oceans. In this activity you will find out how water moves in the Great Lakes system.
