This energy is then transferred to the launched object, which sends it hurling through the air. Upon launch, that potential energy turns into kinetic energy. That means a catapult stores energy, which is called potential energy, when you press down on the lever. But it is important to note, that catapults are more complicated than simple levers because catapults must throw an object rather than lift one.Īll catapults rely on energy. Scientifically speaking, catapults are levers and the projectile (ping pong ball) is the load. How the materials provided create limitations and opportunities for the project.Developing, testing and modifying designs.The effects of the mass of an object on its motion.The strength and direction of pushes and pulls.

This project explores a number of scientific principles. This STEAM activity provides an ideal opportunity for elementary-aged students to participate in open-ended problem solving! Learners can build and manipulate catapults to learn about motion, the history of science and technology, and more! Science Principles Once you’ve followed these steps, you’re ready to play Catapult Bowling!

Pro Tip! The closer the 7-stick bundle gets to the edge, the more leverage the catapult will have.Īdding additional craft sticks to the 7-stack bundle will change the angle of the catapult. An additional rubber band can be tied to the end of the 2-stick bundle to help prevent sliding. To make this combined structure more stable and less likely to shift while launching occurs, tie a rubber band in an X shape at the intersection of the 2 sets of sticks. Now, insert the stack of 7 sticks banded together between the 2-stick bundle. The rubber bands should be as close to the ends of the stack of sticks as possible. Tie another rubber band tightly around the opposite, far end so that all 7 sticks are bound together. Tie a rubber band tightly around the far end of the stack. Take 7 craft sticks and stack them together.

Tightly wind a rubber band around the two sticks on the opposite end from where you glued the cap. Next, place a second craft stick directly underneath the launching lever.
