![]() ![]() This activity is great to use in a science classroom for introducing the concepts of potential and kinetic energy and for practicing the scientific method (make predictions, set up controls, change one variable, record observations). Instructions: Step 1: Put popsicle sticks together Take seven of the popsicle sticks and line them up on top of each other. Popsicle Stick Chain Reaction: a carefully laid network of popsicle sticks results in an awesome display of kinetic energy as the sticks fly apart. Try changing the number of rubber bands you use, or the number of times they are wound around the popsicle sticks and see what happens. While your hand is busy making it, you get to introduce them also to simple physics. Therefore, it will be best to set when your children’s attention is completely on you. Try changing the number of popsicle sticks you use in your catapult and see what happens to the trajectory. 2 catapults out of popsicle sticks Eureka 67K subscribers 2. Popsicle Sticks Catapult This catapult play is intentionally built to demonstrate elasticity. ![]() Playdough is great for this - experiment with different sized pieces, roll them into balls vs making them flatter, launch multiple pieces at the same time. See what happens when different projectiles are used. Set up containers at different distances and see how many projectiles you can launch into the containers.Īssign point values to the containers and see who gets the most points after 10 launches (bonus addition practice).
