Mitch and i have been designing popsicle stick catapults lately and it s been so freakin fun.
Rubber band catapult science project.
Put hot glue over the topmost popsicle stick away from the rubber banded end.
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.
My hypothesis was that it would launch at least 10ft.
What is the science behind rubber band catapult.
Catapult uses math and engineering to build the catapult using glue rubber bands and popsicle sticks.
Figure 6 shows how to do this.
Push the small container into the glue.
It works mainly by using potential and kinetic energy stored in the rubber bands.
Science skills are used to test and hypothesize how far the object catapulted will go.
With this science project you will try your hand at catapult technology.
This catapult worked by storing elastic potential energy.
Your catapult is now ready.
For my science fair project i decided to make a catapult.
Catapults store potential energy by stretching ropes and rubber bands and even by bending and flexing the wooden lever.
Wait for some time until the glue dries.
Check out more catapult designs here design this easy catapult with craft sticks a spoon and rubbers bands.
Only one rubber band will make it looser causing it to launch farther.
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.
The bring science home activity build a catapult showed you how to build a miniature catapult out of popsicle sticks and rubber bands.
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.
Sneak some science into your play time.
The ideal place to tie the rubber band would be at 1 3 rd of the length of the popsicle sticks.
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive.
Finally physics to talk about what happens and why when the catapult is activated.
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.
