Construct 12 models and conduct experiments with them to learn about forces and simple machines. Each model demonstrates a fundamental idea in mechanical physics. For example, you can build a balance scale to learn about lever arms, a freight elevator to

Learn how robotic machines perform work by building six different robotic arms.
Special pneumatic system uses air pressure to power the models to move the robotic arm and a piston to open and close the gripper.
Includes 36-page, illustrated experiment
