Readers won’t have to disassemble their favorite toys to discover what makes them work. This Spanish-translated book explores electric, magnetic, and motion-powered toys from design to function. It introduces readers to six simple machines and explains how they use force and motion to do work. Not every toy is a technological marvel. Readers learn about time-honored favorites including the rocking horse, Slinky, and rattles.
