The unit will consist of two main sections. The first section will provide various opportunities for students to sort and observe various properties of solids, then to do the same for liquids. The second section will provide hands-on experiments to challenge some of the generalizations they may have made during the first section. The experiments will help students to understand how liquids and solids react under certain circumstances. They will understand how energy affects matter and they will begin to understand how the movement of molecules affects the materials we see, touch and eat. The unit includes an annotated list of second-grade reading material for students to learn from and respond to.
