Grades 3-10. For your STEM curriculum.

Learn how gears can easily reduce or increase speed, change force, or transfer motion from one position to another. Discover how worm drives are used to greatly reduce rotational speed and how screws can convert rotational motion to linear while greatly increasing force. Build 12 working models including an experimental crane, a gearbox, a carousel, a helicopter, a screw press, and a crane with a rotating arm. The thorough experiments lead students to discover how the handle’s position affects force and speed, how the crank’s position affects force and speed, how to calculate the mechanical advantage of a screw, what a worm drive is, and how to use a ratchet mechanism. Included booklet contains easy-to-follow building instructions for all models, as well as detailed explanations of the different scientific principles applied and innovative experimental activities for hands-on learning. A quiz section is also available.
