K'nex stem explorations: gear building set

With the KID K'NEX STEM Explorations: Gears Building Set, kids ages 8 and up can create three fully functional gear models like a fan, eggbeater, and a car window using 143 sturdy K'NEX pieces. Kids will explore concepts like gear configurations, rotational speed, mechanical advantage, and more! By building replicas of real-life machines, children gain a concrete understanding of the scientific principles underlying how these machines work. Building also develops fine motor skills, spatial awareness, and problem-solving skills. The KID K'NEX STEM Explorations: Gears Building Set comes with a handy illustrated guide to guide children through their building adventures.
