3rd graders are investigating states of matter during science this year. We observed ice balloons, have developed definitions for matter, solids, liquids, and gases, and will be looking at what causes changes in these states of matter. Students will 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 observe how salt can lower the freezing point of water!
