Kids and teachers can build their own science projects based on exhibits from San Francisco's premiere science museum This revised and updated edition offers instructions for building junior versions, or "snacks," of the famed Exploratorium's exhibits. The snacks, designed by science teachers, can be used as demonstrations, labs, or as student science projects and all 100 projects are easy to build from common materials. The Exploratorium, a renowned hands-on science museum founded by physicist and educator Frank Oppenheimer, is noted for its interactive exhibits that richly illustrate scientific concepts and stimulate learning.
