Are you worried to present your homemade STEM challenge of making catapult in a science fair event!? Without any further thinking, you can add this project to your child’s science fair activity and experience the wow twist in your child’s STEM challenge activity. Not only it works effectively as a STEM activity but also works great to learn simple physics. Let us begin with some STEM challenge activities for kids that allow them to create homemade mini catapults in an excellent way.
Launching ideas to Reality
Designing, measuring, building, recording, and working as a team are the key skills kids will get to learn while participating in this super simple activity. It looks simple but the catapult can shoot up to 6-8 feet which is not far enough to hurt someone so it is cool and safe to construct. If you are looking for other great project ideas be sure to check out these easy and fun paper crafts for kids as well as these fun space crafts. I love activities that require not much more than checking out the recycling bin.
Simple DIY Catapult
In this post, I have included 10 different methods of making mini catapults right from your home or school. Use crafting sticks and a bottle cap to make this super simple catapult. This one actually uses a spoon rather than popsicle sticks.

You can talk about stored energy or potential elastic energy as you pull back on the Popsicle stick, bending it. When you release the stick, all that potential energy is released into energy in motion producing the projectile motion. When you pull down the lever arm all that potential energy gets stored up! Release it and that potential energy gradually changes over to kinetic energy. Gravity also does its part as it pulls the object back down to the ground.

Glue the footings to the bottom of the frame, flush with the sides and 1 inch on center from the ends [3].

The usage of Catapults was very common during middle ages and are less effective than modern weapons. Click on Build a Lego Catapult for young kids to learn all the easy directions. Experimentation and testing are also important for identifying and implementing effective design modifications. Place a small object in the bottle cap and give it a launch and see how far it goes!
So we originally planned to have a cross-brace, which would stop the catapult arm from aiming down and force the release of the projectile at a 90 degree angle to the ground. If you don't want a cross-brace, you'll have to get two more u-bolts and bolt them to the top of the posts so that they face eachother. The cross-brace's top should be flush with the top of the two posts, and should be closer to the shorter side of the base of the frame. Now, start screwing your lag bolts into the cross-brace piece.
How Do Catapults Work?
I remember when the kids were little how in awe they were when they learned you could take a plastic spoon place something in the holder and watch it shoot across the room. Of course, I had to remind them that launching chicken nuggets at their brother was not the way to test accuracy and precision. Again this is a brilliant easy engineering project for kids with lots of possible variations on the design and theme. For your mini catapult, you’ll want to consider objects that are generally round, light enough that your catapult can toss them, but not so light that you can't predict their flight. What properties allow one catapult to launch further (or higher) than the others. The simplest design is a lever system for the launch mechanism.
Build Catapults using Popsicle or Lolly Sticks
Kids can experiment with different designs, sizes, and materials to optimize the catapult’s performance. This process involves testing, data collection, and analysis to find the most effective design. They can also have fun adjusting their catapults to see how far they can launch objects.
Also, supervise the use of scissors or any cutting tools required for the project. This type of project encourages critical thinking, experimentation, and the application of knowledge to solve a problem — all essential components of STEM education. Kids use mathematical concepts to measure and cut popsicle sticks accurately.
Test different configurations, explore how variables affect launch distance, and inspire young minds with this playful learning experience. Keep it enjoyable and educational as you guide your kids through building and customizing their very own popsicle stick catapult. Ready to engage your kids in a fun and educational activity?
Making a popsicle stick catapult is an engaging and educational activity for kids, ideal for science projects or just for fun. As children build their catapults, they not only get a chance to craft a playful toy but also learn fundamental principles of physics, such as levers and the conservation of energy. Engage your children in a thrilling hands-on learning experience with the Pompom Launcher activity from STEAM and Make. This instructive project introduces the basic principles of physics and engineering by guiding kids through constructing their very own miniature catapults.
These catapult designs offer varying levels of complexity, allowing kids to experiment with different materials and learn about how simple machines like levers and springs work. This ingenious device demonstrates basic principles of physics and engineering, teaching kids about levers and energy transfer as they launch small objects into the air. Once that was done, it was time to make the rest of the arm.
This simple yet effective design encourages experimentation and problem-solving as kids adjust the catapult to achieve different distances and angles for their launches. As the centuries passed, catapult designs continued to evolve. Engineers and military minds refined their craft, experimenting with various designs, materials, and power sources. To hurl things farther, faster, and with greater precision.
With clear instructions and a list of required materials, this project encourages hands-on learning and creativity while ensuring safety with proper supervision. Enjoy this practical science experiment that demonstrates the power of potential and kinetic energy in an accessible and enjoyable way. The Roman empire's onager catapult used torsion—twisting an object, in this case a restraining rope or spring, by applying torque—to build tension in the arm and generate a powerful swing. Our design can't quite do that, but it's perfect for kids to build and use in games and experiments. Da Vinci was an engineering genius and way ahead of his time. This kit includes pre cut wooden pieces to build his catapult design.
