Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups, they follow instructions to a recipe and make ice cream by shaking the ingredients in a freezer bag.
