In Dan Zettwoch's Science Comics: Cars , you'll learn where cars came from and how they work. When you pop the hood, what are you looking at? How does gasoline--or electric batteries, or even steam--make a car move? Rev up your motor and take look at the combustible history of the automobile and its explosive effects on our modern lives. Every volume of Science Comics offers a complete introduction to a particular topic--dinosaurs, the solar system, 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!
