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

Let the challenges begin! Kids develop STEM skills fit for kings and queens every time they build with the Engineering & Design: Castle set from Learning Resources.

Build ten sleek and updated models of catapults and crossbows. These classic siege weapons from the middle ages also happen to be great tools for teaching physics, including lessons in force, energy, motion, and projectiles.
