Rubber Band Catapult Science Project

The ideal place to tie the rubber band would be at 1 3 rd of the length of the popsicle sticks.

Rubber band catapult science project.

With this science project you will try your hand at catapult technology. Mitch and i have been designing popsicle stick catapults lately and it s been so freakin fun. Push the small container into the glue. Check out more catapult designs here design this easy catapult with craft sticks a spoon and rubbers bands.

Put hot glue over the topmost popsicle stick away from the rubber banded end. Science skills are used to test and hypothesize how far the object catapulted will go. The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. For my science fair project i decided to make a catapult.

I think it will launch 10 ft because i only put 1 rubber band around the the popsicle stick that will be launching the tinfoil ball. Catapults store potential energy by stretching ropes and rubber bands and even by bending and flexing the wooden lever. Sneak some science into your play time. Finally physics to talk about what happens and why when the catapult is activated.

Figure 6 shows how to do this. Only one rubber band will make it looser causing it to launch farther. To measure x 0 you will have to measure the length of the rubber band while it is unstretched but flat. These simple catapults are quick and easy versions of the real thing using a fulcrum instead of a spring so kids don t knock their teeth out.

It works mainly by using potential and kinetic energy stored in the rubber bands. Using a rubber band powered catapult you will send ping pong balls flying through the air. My hypothesis was that it would launch at least 10ft. This catapult worked by storing elastic potential energy.

For the rubber band we recommend measuring your own values in case the type of rubber bands shipped with the catapult kit change over time. Wait for some time until the glue dries. Catapult uses math and engineering to build the catapult using glue rubber bands and popsicle sticks. Your catapult is now ready.

The more energy you pack in the higher your ball will go. Potential energy is the store energy where as the kinetic energy is the energy in motion.
