Gears, Sprockets & Chains is our newest classroom module to expand on the “engineering go power” of the base Structures module. Colorful gears and chains (like those in a bicycle) are one of the most exciting simple machines. When students learn to design and build with gears they gain a fun-filled, hands-on understanding of the principles of motion, energy and speed. Each activity is focused on solving real-world challenges using creativity, the design process, and a problem based learning approach. A sturdy, lightweight container keeps over 500 pieces organized. A super value with access to over 80 online lessons and activities provided. Requires Structures Classroom Module. Ages 4 and up.
