Working with Materials: Changing Materials

Product Description

In Changing Materials we look at how materials change when we do something to them. A liquid can become a solid when we freeze it, gases can turn to liquid when they cool down and a solid can change into a liquid when it is heated. Materials are changing all the time from baking a cake and melting ice to burning a candle. Try some of the experiments in this book to see how you can make the materials around you change.
