Catapults are a classic building activity for kids. Believe it or not, catapults have been around since medieval times. Catapults are a tool used 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 to do.
How Does a Catapult Work?
Don’t forget to take the learning beyond making the catapult and into math and more science! The science behind a catapult is physics. A catapult launches with stored energy. The energy used with catapults include tension, torsion, and gravity.

Asking open ended questions is a fantastic way to keep the learning rolling.
Here are a few ideas for catapults:

- Switch up the launching object
- Build other types of catapults and see how changing the materials mixes up the energy
- Ask a lot of what happens if and what happens when questions
