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.
How Can Disappearances Within the Triangle Be Explained?
Investigating multiple hypotheses, students discuss the values of using several data types and sources to
solve a science problem, demonstrate how bathymetric charts are used and constructed, demonstrate how weather information is mapped and interpreted, and explain how scientists use multiple working
hypotheses to solve complex problems.
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.
How well do you know the Great Lakes?
Many people, including a large portion of those who live close to the Great Lakes, do not a have a basic understanding of the individual characteristics of and the differences between the lakes. Since it is difficult to understand many of the Great Lakes issues, such as global climate change, pollution, and water use without a basic understanding of the lakes, this activity is designed to help visualize the differences in volume, shoreline length, human population distribution, and fish populations of the Great Lakes.
