In a series of fun and involving hands-on biology experiments, kids learn how light affects the color of grass, how light affects seed germination, where carrots store their food, and how environment changed the body temperature of dinosaurs. They will also determine whether or not dinosaur eggs were laid in open nests, how a fish hears without external ears, and how toothed whales "see" with their ears. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave shows just how much fun science can be.
