Each topic in this picture book, such as Why does ice melt? and What happens when ice freezes?, is introduced with a two page story that concludes What do you think? Turn the page and there is an experiment that the kids did to test their theories, an explanation of why the result is what it is, and another experiment for you to do at home (explanations of the results are in the back). Very enjoyable experimentation for the preschool set. ( )
