Engino STEM Mechanics - Gears and Worm Gears

With this Engino - Discovering STEM set, you'll learn how gears can increase speed, decrease speed, and transmit force and motion. You'll discover how a worm gear can be used to reduce speed and how a screw can convert circular motion into linear motion, thereby increasing force. Build 12 exciting models, including a crane, gearbox, swing carousel, tower crane, screw press, and helicopter. The easy-to-follow instructions are available online and in the included booklet. You'll learn about the physical principles underlying these machines and learn fun facts. There are experiments you can do yourself and even a quiz to test your new knowledge.
