Does a substance dissolved in liquid disappear? If not, where does it go? Could it ever come back? As young students ponder these ideas and gain experience mixing and observing different solutions, they benefit from this very positive early experience with chemistry. The activities focus on dissolving, evaporation, and crystallization. Students create homemade "gel-o," colorful disks, and crystals that emerge on black paper to make a "starry night."
Involving Dissolving is one of more than 70 teacher's guides and handbooks from the Great Explorations in Math and Science (GEMS) program. GEMS guides are tested in classrooms nationwide and come with clear step-by-step instructions, assessment suggestions, literature connections, and ideas for further investigation. GEMS units can be used as a strong support to leading science and mathematics standards for educational excellence. GEMS guides are developed at the Lawrence Hall of Science, the public science education center at the University of California at Berkeley.
