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.
Students remove measured amounts of water from a five-gallon bucket, simulating the amount of fresh water available on earth.
Making Great Lakes Connections
Groups of learners work on a single Great Lake and connecting waterway and then come together as a class to construct a simple three-dimensional model of the Great Lakes. Individual groups also
present their Great Lake and connecting waterway information.
More Than Just a Lake!
By creating a map of the rivers flowing into your Great Lake, learn how rivers form a watershed.
Your Great Lake!
How much water does each Great Lake hold? Use this lesson as a demonstration or a classroom lesson to create visual representations of the Great Lakes, Lake Baikal, and the relationships between surface area, retention time and pollution effects.
