Smithsonian Motor-Works

Smithsonian Motor-Works Kick-start an interest in mechanical engineering with the Smithsonian Motor-Works Kit — a hands-on STEM activity that lets kids build a functioning model engine from the inside out. Following step-by-step instructions, young engineers assemble cylinders, pistons, gears and ignition components to create motion just like a real internal combustion engine. Once complete, flip the switch and watch the engine come to life as the pistons fire in sequence — with light effects that simulate spark plug ignition and a clear viewing chamber so kids can observe every moving part. Along the way, they learn how engines generate power, why timing matters, and how machines keep our world moving. Perfect for science fairs, classroom demonstrations, homeschool lessons or simply weekend building fun, Motor-Works encourages confidence and curiosity through meaningful hands-on exploration. Smithsonian educational quality ensures a kit that both entertains and
