Make it a fun competition between the kids to see how can design the best catapult. If your kids love STEM activities this is a great way to get them excited about engineering. How do heavier items do compared to light items?īuilding catapults is a great way to learn about physics even at a very young age. Does this make a difference in the launch power? This ensures that you get the most accurate results possible. Try several methods using the same object that you launch. freddle on May 01, 2009: thanks i got an a+on my project tht is sweet. Be sure you try different angles that you pull the arm nack with as well as hard quickly you let go. Thanx so much for the catapult plan, you helped us make a great catapult for our D.T project although i must admit ours looks a lot better than urs haha xx. Once you create your catapult you will want to observe how it does. Place a small object in the bottle cap and give it a launch and see how far it goes! Make adjustments as needed to make this catapult the best yet. Whether you have a box of Legos, a stack of popsicle. Remember this is where you will put all the things you will launch! Building a catapult is a fun project that combines creativity, problem-solving, and hands-on learning. On the top stick on the side opposite the rubber band, you will want to carefully glue your bottle cap. You will then rubber band only one side of these two sticks leaving the other side to be able to bend and move. Take two craft sticks going the opposite direction and place one underneath your sticks and one on top. You will want to rubber band these on both sides tightly together. This is a great catapult for smaller kids to create.įirst, you will want to stack 5 craft sticks on top of each other. In order to create this simple craft stick catapult, you will need rubber bands, a bottle lid, and craft sticks. This time you will want to carefully pay attention that you cut pieces accurately and glue and rubberband just at the right points to ensure your catapult is in perfect working order. The final step is to build your final catapult. How well does it launch? Should changes be made? Improve upon this design. You will want to test your model if multiple objects in the catapult. This is more like your test model so that you can alter it and make the necessary changes. Next, you will want to gather your supplies, possibly head to the store and then you can build a simple design to see if your idea works. Plan the materials that you might need to build the perfect catapult for your school project. Think about it, brainstorm, talk to others to get ideas. Once you discover this then it is time to imagine how to do it. So first you will want to start with a plan. So often we jump right into a project without a direction or plan. Cut up sponges (you can get these wet!)īefore you begin you will want to evaluate these 6 steps in order to build a catapult.You never want to use sharp or heavy objects that can hurt someone if it was to hit them by accident. Safety is the number 1 concern when it comes to launching things in your catapult.
