The California Department of Education and the foundation of the electronics firm, NEC, developed this great website that has snack-sized versions of many of the experiments at the Exploratorium in San Francisco, California. The Exploratorium is a museum of science, art and human perception, and the Science Snacks website has more than 50 experiments for kids, and curious adults, to learn more about the world. The experiments are listed in alphabetical order, and have a one-sentence description of them next to their name. But, the descriptions sometimes intrigue more than elucidate, as in "Wiggle where you're at," which is an experiment about "Proprioception." "The Condiment Diver," is an experiment showing "The world's simplest Cartesian diver." Teachers interested in having an actual book of snack-sized experiments should check out the link to the latest "Snackbook," called Square Wheels, at the top of the homepage. There are several sample pages from the book that can be viewed as PDFs, as well as a link to buy it from their online store.
