We have added a new kit to our STEM Kit collection that allows you to build a mechanical model of the solar system including the sun and eight planets, wind it up, and watch the planets revolve around the sun. Assemble this machine using snap-together plastic parts to learn how the gears and wind-up mechanism work to spin the model.
The Kit is available for checkout to CAPL cardholders ages 18+ for three weeks and one renewal is available if no holds are pending. See the Orbiting Solar System STEM Kit in our catalog.
