Ah catapults - a classic and exciting engineering project that introduces students to fundamental ideas in physics and engineering like energy transformation, trajectory, and structural strength.
Step 1: Simple Catapult
Step 2: Leverpult
Step 3: Slingshot
Step 4: Advanced Ideas
A straightforward advancement of the Catapult project is to add two baskets instead of one.
A wacky design, dubbed the Confused Catapult, incorporates two catapult arms onto one frame. Making catapult arms of different lengths allows the user to enjoy a wider range of trajectory options.
