Can we build a bird feeder that keeps squirrels out? Where do earthworms like to live? Does color affect human emotions? Readers will learn the answers to these questions and more with the fun experiments in this book. Young scientists will observe and explore behaviors of animals’ interactions with environments. Many experiments include ideas they can use for their science fair.
