The Great Lakes are vast, and provide fabulous laboratories for people to learn about everything from hydrology to cultural geography. This remarkable collection from NOAA brings together multimedia, lessons, real-world data, and background information about these bodies of water. The homepage features a meditative narrative essay that combines topographic description with general observations about the economic and other activities that take place in the general region. The Multimedia area contains a voluminous photo gallery, a fantastic "Listen to the Lake" podcast, and several Great Lakes webcams. Moving along, science educators will be delighted to learn about the Lessons and Activities area. Here they can download activities that include "Nab the Aquatic Invader," "Fish Life Cycle," and "Great Lakes Connection Model." Further along, the "Great Lakes Literacy Principles and Fundamental Concepts" document provides a framework for educators teaching about the Great Lakes. The site is rounded out by the Background Information area, which includes web diagrams of the Great Lakes food chains and information about migratory birds in the region.
