Catapult Engineering

Investigate physics using technology from medieval times! Build six sleek, updated models of catapults, trebuchets, and other medieval launchers. 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. Build 6 functional models of catapults, crossbows, and other medieval siege weapons that launch foam balls and soft darts

A catapult is a medieval ballistic device that uses mechanical rubber bands and counterweights to fling projectiles — in this case, foam balls — into the air. The 32-page, full-color manual has illustrated step-by-step instructions for building the models and conducting the experiments.

For ages 8 and up.
