3rd Grade Geode Making

In a wonderful art/science collaboration, Jody and I made beautiful geodes with 3rd Grade as a part of their study of rocks and minerals. First, in art class, the students created the geodes out of clay formed around real rocks and glazed the insides of the geodes. In science class, using aluminum sulfate, the students made crystals inside of the geode halves. The results are really spectacular!
