STEM Pneumatics teaches the basic principles of pneumatics, and demonstrates the functioning of components like compressors, pneumatic valves and cylinders, as well as an exhaust throttle valve. The first experiments with pneumatics were conducted in the third century B.C., which led to the discovery of the extreme versatility and usefulness of compressed air. Using 8 models and 29 experiments, this kit also includes a full set of lesson plans for teachers.
