How Do You Build Catapults For A Science Project?
Students will build a catapult to learn about motion and the forces acting upon the projectile. Catapults were used in history to launch a projectile that smashed buildings and walls during a siege. These weapons of war will now teach students about the forces involved in moving a projectile or acting upon the projectile to put it in motion and the energy required to do so. Glue together one whole Popsicle stick to one half Popsicle stick to form an L. Repeat the process to make another L. Glue the two Ls together to form a rectangle. Make two more Ls from Step 1’s instructions and glue them together to form another rectangle. Lay one rectangle on top of the other and glue them together to form the base of the catapult. Mark the middle of the rectangle on both sides with a pen. Glue two half sticks flat side down to your pen marks. These half sticks form uprights that are perpendicular to the foundation. The two uprights should be directly across from each other. Glue a half stick to t
