Exploring the Great Lakes CD-ROM
Exploring the Great Lakes CD-Rom teaches students about our five Great Lakes and the steps that the Environmental Protection Agency (EPA) is taking to monitor and solve potential environmental problems. The Lake Guardian is an EPA owned and maintained 180 foot, self-contained, non-polluting research ship that travels the five Great Lakes. A special feature of this CD is the interactive panorama of the ship that allows users to control the video viewing direction. A Youth Activity Sheet and Teacher key is included on the Teacher CD ($9.95 each). Both versions (student and teacher) contain a copy of the information-rich resource, the EPA Great Lakes Atlas.

Purdue Media Distribution numbers: CD-AE-100 (Teacher version); CD-AE-100a (Student Version).
