States of matter

2nd and 3rd graders are investigating states of matter: observing ice balloons, developing definitions for matter, solids, liquids, and gases, and looking at what causes changes in these states of matter. Students end the unit by making a polymer GAK and determining if it is a liquid or a solid. We will also make ice cream and watch salt lower the freezing point of water!
