About this item

Learn the fundamentals of mechanical physics by building and testing all six classic simple machines—wheels and axles, levers, pulleys, inclined planes, screws, and wedges—plus gears. This hands-on kit includes 26 model-building exercises that progress from basic to complex, a spring scale to measure forces, and a 32-page full-color guide with real-world examples. Durable, modular pieces assemble and disassemble repeatedly, letting you experiment endlessly and discover how physics works all around you. From Thames & Kosmos, for ages 8 and up
