A cracked smartphone, a forgotten waffle iron, a beat-up skateboard, some old skis.. in the world of the ReBotz, old tech and discarded junk are given new life. Quickly piece together a motorized model of a ReBot from a set of easy-to-assemble parts. Then, switch it on and watch how the robot moves in a unique and wacky way. Collect all four kits and mix up the interchangeable parts to make your own rebooted robotic creations. These science-fiction models provide an opportunity for some real science lessons. Conduct experiments with the different simple machines and mechanisms that make the robots move, including cams, springs, sliders, cranks, motors, wheels, and levers.Details:13 piecesFast and easy to buildDemonstrates wheels, slider cranks, and motors in actionPowered by an electric motorCombine the parts from different ReBotz kits to build your own creationsFor ages 6 and up
