Matter on the Move

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also means an increase in molecular motion. Make sure to consult the teacher's lab manual for background information, a unit overview, and other related resources.
