Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work. For example, they will feel the difference between a single and a multiple pulley system when they use the two systems to lift the same load. Covers concepts of work, power, mass and more. Includes 18 single-sheave pulleys, 12 double-sheave pulleys, 12 triple-sheave pulleys, six spring scales (500g/5N), roll of twine (107m/350ft.), 20 pulley chain links, and Pulleys In Motion Teacher’s Guide.
