Lloyd H. Barrow guides the reader in exploration of one of the many small animals that live in the ground; earthworms. Barrow's detailed science experiments will help beginning biologists create winning science fair projects. Readers will make observations about earthworm structure and behavior, movement, preferences, and reactions. Included in the book are easy-to-follow diagrams that offer readers exact information on performing the experiments. None of the experiments in this book in any way harm the worms.
