With this updated version of the Early Simple Machines Set, young students build fun and simple models such as a seesaw, rolling vehicle, spinning top, raft, and many more. By playing with and manipulating the models, children experience pulleys, levers, gears, and wheels and axles while exploring energy, buoyancy, and balance. The set is designed for use by teams of two or three children. It includes full-color activity cards with pictorial instructions for eight models; a plastic punch-out sheet with eyes, sails, scales, and wings; and a plastic bin for easy cleanup and storage.
