This simple science experiment can be used over and over for hours of fun! You can make these five-step catapults with materials you likely have at home. These easy catapults can be used to explore multiple engineering and physics concepts. Give them a try using the instructions below. You can check out these titles on Hoopla for other catapult designs: Stomp Rockets, Catapults, And Kaleidoscopes and The Art of the Catapult.
The earliest written records of catapults date back to the 3rd century BC. That’s over 2,300 years ago! Catapults were used in many ancient wars to launch things over high castle walls. Catapults use physics to store energy and then release it very quickly to fire an object. The three main energy storage tools are tension, torsion, and gravity. There are many types of catapults that all work a little differently. Your popsicle stick catapult stores potential energy when you pull the spoon down. When you let go of the spoon, the potential energy changes to kinetic, and your object flies!
