Hand clipper

The "Hand Clipper" STEM kit, featuring a mechanically operated claw, immerses children in the fascinating world of mechanical engineering and simple machines. This kit teaches the principles of levers and linkages, demonstrating how the motion of closing a fist can be translated into the mechanical action of a claw closing. As children assemble the clipper, they gain hands-on experience with the concept of force transfer across different parts of a mechanism, learning how applying a small amount of force on the handle can result in a larger force at the claw, effectively showing the principle of mechanical advantage in action.

Moreover, this STEM kit delves into the basics of kinematics—the study of motion—without delving into the forces that cause it. By manipulating the claw, students explore how the orientation and length of linkages affect the movement outcome, providing a practical demonstration of how machines can convert human motion into various mechanical actions. The "Hand Clipper" kit not only deepens understanding of mechanical principles but also stimulates innovation and critical thinking, encouraging young learners to ponder how mechanical systems are designed to accomplish specific tasks. Through building and operating the claw, students are introduced to the engineering behind robotic arms and other mechanical grabbers, bridging concepts of physics with real-world applications.
