Fodor's Expert Review Biosphère
Nothing captures the exuberance of Expo '67 better than the geodesic dome designed by Buckminster Fuller (1895–1983) as the American Pavilion. It's only a skeleton now—the polymer panels that protected the U.S. exhibits from the elements were burned out in a fire long ago—but it's still an eye-catching sight, like something plucked from a science-fiction movie.
Science of a nonfictional kind, however, is explored in the special environmental center the federal government has built in the middle of the dome. It focuses on the challenges of preserving the Great Lakes and St. Lawrence River system, but it has lively and interactive exhibits on climate change, sustainable energy, and air pollution. Kids and others can use games and interactive displays arranged around a large model of the waterway to explore how shipping, tourism, water supplies, and hydroelectric power are affected.
