Build a Wooden Catapult
Assemble a wheeled wooden catapult with this DIY STEM engineering kit. Its visible frame, arm and elastic bands make a hands-on introduction to simple mechanical structures.

Explore Forces and Movement
Study how the moving arm and elastic bands work together in a catapult model. Building and observing the mechanism encourages thoughtful questions about stored energy and motion.

Keep Experiments Supervised
Use only soft, lightweight test pieces under adult supervision. Never use real stones or aim at people or animals; keep the learning space clear.
