Catapult Science
Even though kids will see catapult play as fun and games, there is a ton of science involved. Using a simple catapult design you can learn about kinetic energy in an easy way.
Catapults can also teach about simple machines and elastic potential energy and even about what a pivot point is. If you are looking into adding some learning into this activity, I thought these resources were helpful:
- Launch into Learning from Teach Engineering
- The Science Behind the Catapult
- All About Catapults from All Things Medieval

Catapult Projectiles for Kids
Obviously whether you are playing inside or outside will be a big component of your decision on what to use as catapult projectiles.
Safety is the other big one! The last thing you need is an ACTUAL weapon in your house.
The good news is that modern life has provided many alternatives to the medieval rock. Start with one of the suggestions below, but get the kids involved in finding soft and safe alternatives.
Safety glasses is always a great idea when playing with flying objects!
- Crumpled paper balls
- Marshmallows
- Craft Pom-poms
- Sponge “bombs” or sponge pieces – wet or dry
- Cotton balls
- Ping pong balls
- Duct tape or masking tape balls
- Stuffed animals
- Hacky sacks or small soft/squishy play balls
