In this activity students learn what a catapult is and what it was used for, then are challenged to build one themselves. Students use a variety of materials to build a catapult to launch a ping pong. It can be a great addition to a simple machines unit. Two versions are included: one where they launch the ball as far as possible and one where they try to land it on a target. Included is an explanation of catapults that can be used before or after the challenge.
Students LOVE this project...and the balls do not go very far so it can be done in a smallish space. :) This is a great activity to do to focus enthusiastic students!
