"Go through the trial and error phases and then make your adjustments. Potential energy is the store energy where as the kinetic energy is the energy in motion. It works mainly by using potential and kinetic energy stored in the rubber bands. "You need to design a structure to launch a piece of candy corn the farthest," explained Ms. What is the science behind rubber band catapult The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. That was the STEM challenge posed to students by math teachers Melissa Ruggiero and Lauren Santangelo.

Attach one side of the firing arm to the central plate on the base.Remember to set it aside to dry for a few minutes before you continue. Don’t be shy with the glue at this stage as you want the firing arm to be solid. Glue the four sticks on to the bulldog clip, sandwiching the metal arms between the sticks.Opportunity4All Help create equal opportunity for all kids.Shop 4‑H Shop activities, supplies and more.4‑H at Home Educational activities for kids to do at home.4‑H Youth Voices Learn how 4-H youth are making a difference.Luminaries Celebrating influential 4-H alumni.
