Changing Materials (Working with Materials)

Children will be amazed to learn that a liquid can become a solid when it freezes, gases can turn into liquids when they cool down, and a solid can change into a liquid when it is heated. This magical new book for children explains in a simple way how materials change when we do things like bake a cake, melt ice, or burn a candle. Easy experiments also show children how to change materials using common household items.
