Amazon.com Product Description (ISBN 0924886633, Paperback)Young students learn to look beyond the obvious in this series of highly involving activities on dissolving, evaporation, and crystallization. Using familiar substances, students create homemade "Gel-o," colorful disks, and crystals that emerge on black paper to make a "starry night." Does the substance disappear? If not, where does it go? Could it ever come back?
