People in the Bay Area love to cook, and that can mean mixing up everything from home-grown arugula to free trade pumpkins. The good folks at San Francisco's Exploratorium have cooked up the Iron Science Teacher presentations in an attempt to bring together the worlds of science and the culinary arts. To no one's surprise, they have succeeded, and the results include a fine mix of science activities that are both fun and enlightening. Visitors can dive right in by looking over some of their recent endeavors, which have included such items as candy, apples, chocolate, fruit cake, pumpkins, and marshmallow peeps. There are other areas of the site that bring together previous webcasts that have covered kitchen items, common household items, and even things one might find in a recycling bin.
