Every volume of Science Comics offers a complete introduction to a particular topic-dinosaurs, the solar system, volcanoes, bats, robots, and more. Whether you're a fourth grader doing a natural science unit at school or a thirty-year-old with a secret passion for airplanes, these books are for you! In this volume, a sister and brother agree to help a talking spider find her missing child, but they don't realize that it will take them on a journey across the globe! Along the way they'll meet spiders who live in every environment imaginable, from their own backyard to the Australian Outback. Although they seem scary at first, once you learn why spiders have gotten such a bad reputation you'll see that spiders are actually here to help!
