Making a catapult is fun to spend an afternoon with your kids learning about science. Not only is designing a homemade catapult entertaining, can also teach them some basic physics principles. Catapults for kids are a perfect science activity for parents, too.
Plus, there are so many ways to make a catapult that you can tailor the project to fit your child’s interests and abilities. For example, my son wants a catapult that shoots far!
Below are 10+ of the best ways to make a catapult with kids. Enjoy!
What are Catapults?
Catapults are a classic building activity for kids. Believe it or not, catapults have been around since medieval times. Catapults are a tool to launch an item a great distance without additional aid from explosives.
History & Purpose
They have been proven to be one of the most effective mechanisms during warfare. That is pretty amazing, given that making a catapult is relatively easy.
How Do Catapults Work?
Don’t forget to take the learning beyond making the catapult into math and more science! The science behind a catapult is physics. A catapult launches with stored energy. The energy used with catapults includes tension, torsion, and gravity.

Further Learning about Catapults
Asking open-ended questions is a fantastic way to keep the learning rolling.
Here are a few ideas for catapults:
- Talk about projectile motion and ask for predictions on how far various objects will go
- Switch up the launching object
- Build other types of catapults and see how changing the materials mixes up the energy
- Ask a lot about what happens if and what happens when questions
