Rubber Band Catapult Science Project

Catapults store potential energy by stretching ropes and rubber bands and even by bending and flexing the wooden lever.

Rubber band catapult science project.

My hypothesis was that it would launch at least 10ft. Using a rubber band powered catapult you will send ping pong balls flying through the air. To measure x 0 you will have to measure the length of the rubber band while it is unstretched but flat. Mitch and i have been designing popsicle stick catapults lately and it s been so freakin fun.

Potential energy is the store energy where as the kinetic energy is the energy in motion. Put hot glue over the topmost popsicle stick away from the rubber banded end. Check out more catapult designs here design this easy catapult with craft sticks a spoon and rubbers bands. The bring science home activity build a catapult showed you how to build a miniature catapult out of popsicle sticks and rubber bands.

The ideal place to tie the rubber band would be at 1 3 rd of the length of the popsicle sticks. Your catapult is now ready. Sneak some science into your play time. Catapult uses math and engineering to build the catapult using glue rubber bands and popsicle sticks.

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. With this science project you will try your hand at catapult technology. Finally physics to talk about what happens and why when the catapult is activated.

The more energy you pack in the higher your ball will go. 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. It works mainly by using potential and kinetic energy stored in the rubber bands.

This catapult worked by storing elastic potential energy. What is the science behind rubber band catapult. Push the small container into the glue. The catapult s design makes it easy to measure and repeat how hard the ball is launched and its direction so you can find the right catapult settings to hit the target reliably.

Figure 6 shows how to do this. 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.
