This wonderfully illustrated education book, part of the award-winning SAE International - A World in Motion program, teaches engineering principles to primary-age children through an imaginative and exciting story. Malarkey was a lazy cat. But he was a hungry cat, too. To catch some mice, he built a trap. Will his trap work in time for dinner? Malarkey certainly hopes so-but the mice may have other plans of their own. In Malarkey and the Big Trap, readers will follow this crazy cat’s antics while he tries to build a better mousetrap. During the fun, readers will explore the behaviors of different components and how launch position can affect the whole process, similar to a pinball machine with ball traps and bumpers.
