描述
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?
