Cars take us to work. To school. To soccer practice. To the grocery store and home again. Can you imagine a world without them? It's not so easy! One of the reasons we can use cars so much in our everyday lives is because they are safe to drive. But that hasn't always been the case. If it weren't for the experiments conducted over decades that involved all kinds of crash test volunteers―dead, alive, animal, or automated―cars as we know them might not be around. And then how would you get to school? Filled with historical photographs, graphics and humorous illustrations, this nonfiction book from science educator and award-winning author Jennifer Swanson will appeal to lovers of all things that go and readers who are interested in getting under the hood and seeing how things work.
