![]() Many medieval trebuchets were larger and could hurl projectiles even farther than catapults. The third is the equation for the trajectory of their catapult. The second is a paper which requires students to explain the mathematics behind a catapult. The first is the creation of a catapult, which my students made out of Popsicle sticks and rubber bands. Read more about the science behind the catapult and simple ways to create a catapult science experiment below STEP 3: Test and measure how far each item goes when flung from the catapult. Make a catapult out of clothespins and use it to shoot pom pom birds to a target. Then the counterweight is allowed to fall, rotating the lever arm and converting that potential into kinetic energy in the projectile, which is flung through the air. STEP 2: Hand out supplies to each individual or in small groups, and build a Popsicle stick catapult following the instructions below. When the counterweight is raised up, it has lots of gravitational potential energy. 3 Place the second large popsicle stick under the fifth. 2 Insert one large popsicle stick between the first and second small popsicle stick in the five-stick bundle. Use two rubber bands to tightly wrap each end of the stacked popsicles. 4 Place another popsicle stick on top of the stack making a ‘T’ shape. POPSICLE STICK CATAPULT 1 Make a stack of five small popsicle sticks. You will be using small pom poms and pencil erasers as projectile. ![]() Your projectile is what you will be testing You want to use the right projectile so that your catapult launches it the farthest distance. You will use a soda pop bottle cap as a bucket and place your projectile in there. 3 Place one popsicle stick under the stack making a ‘T’ shape. The catapult will be made out of popsicle sticks and rubber bands. 32 Popsicle sticks, some masking tape, pencil, rubber band, scissors, X-acto knife (optional), piece of paper about 6 inches square. 2 Secure the popsicle sticks by wrapping two rubber bands around the stack. A trebuchet has a lever arm with a large, heavy counterweight on one end and a smaller projectile on the other end. 1 Take 12 popsicle sticks and stack them together. It relies on gravitational potential energy-the type of energy you get by raising something up off the ground. Browse to get the complete details of this super classic STEM activity: Build Catapults using Popsicle or Lolly Sticks. Kids can experiment in different ways to build super cool catapults that shoot farther and more powerful. This catapult works by storing elastic potential energy-the type of energy you get from stretching something such as a rubber band or a spring-and rapidly converting it to kinetic energy (the energy of motion) of a projectile (in that case a cotton ball).Ī trebuchet works differently. Check out this brilliant idea of making catapults while exploring STEM in this awesome and simple STEM project. The Science Buddies activity Build a Popsicle Stick Catapult shows you how to build a miniature catapult out of popsicle sticks and rubber bands.
