CLASS SET Gears 15 models - 100 pieces

How does a cone gear wheel, a belt drive or a rack and pinion drive work? What happens if the gear ratio changes? Young researchers can discover the answers to these and many other questions through 15 models and twelve experiments. The models are quick and easy to build in the classroom, and the pre-designed tasks and solutions are a great addition. A class set contains 16 individual sets and is suitable for 30 pupils and one teacher, for example.
