Key concepts Physics Engineering Elastic potential energy Projectile motion. The energy was stored in the potential energy of the counterbalance. What I did was connected a kitchen spoon (to hold what I'm launching-a hacky sack) to the arm of the rat trap with rubber bands and glued a soft pad on the end to keep from breaking the spoon because of the impact. They also use their catapults to create a claim, develop an experiment to test their claim, and use evidence from the experiment in their reasoning. Measure the distance, and see which catapult design launches the farthest. Explain the relationship between the law of conservation of energy and the way a catapult launches a cannonball. That’s right, instead of using a stack of craft sticks for our fulcrum, we thought a round, somewhat springy cork would make a better fulcrum. Take a single craft stick and place it perpendicular to the stack on the bottom, start by setting the fulcrum about a quarter of the way up the single stick. Track your progress and get personalized recommendations. Each project is a STEM Challenge that will get your young STEMists excited about the engineering process.
