Popsicle Stick Catapult
Let's go back to medieval times full of Queens, Knights, and Castles! In order to break down castle walls knights would use catapults, similar to the one we make in this STEM activity!
Catapults work by transferring energy from one form to another and from one object to another. When you pull the popsicle stick back and prepare to launch you add stored/potential energy to it. When you release this energy is converted to kinetic energy, known as the energy of motion.
