Build a Mini Catapult Challenge
Create your own mini catapult using household items and see how far you can launch small objects. This fun STEM activity encourages experimentation and problem-solving skills while providing hours of engaging play.
Safety notes
Ensure supervision for younger children and avoid launching objects at people or pets.
What you will need
- Plastic spoon
- rubber bands
- small objects to launch (like marshmallows or pom-poms)
- cardboard
- tape
Step-by-step instructions
- Gather Supplies: Collect all the materials listed above before starting.
- Make the Base: Cut a piece of cardboard into a rectangle about 12 inches long and 6 inches wide to serve as the base of your catapult.
- Attach the Spoon: Use tape to attach one end of the plastic spoon to one end of the cardboard base, ensuring it can pivot up and down.
- Create the Lever: Secure two rubber bands around the spoon and the base to hold it in place while allowing it to move freely.
- Load the Catapult: Place a small object in the spoon, pulling it back to create tension before launching.
- Launch and Measure: Release the spoon to launch your object and measure how far it flies. Record your distances!
- Experiment with Design: Try changing the angle of the spoon or adjusting the base to see how it affects the distance.
Parent guide
Encourage your child to explore different designs and ask them to predict how changes will affect the launch distance. Discuss the physics behind the catapult, such as force and motion, to enhance their understanding.
Educational benefits
- Enhances problem-solving skills
- Introduces principles of physics through hands-on learning
- Encourages critical thinking and experimentation
Why this works as a screen-time alternative
This hands-on activity replaces screen time by engaging kids in a fun, creative project that sparks their curiosity and scientific thinking.
Frequently asked questions
What can we use as small objects to launch?
You can use marshmallows, pom-poms, or even small balls of paper!
Is this activity safe for younger children?
Yes, but younger children should be supervised to ensure safe play and proper handling of the materials.
How can we make it more challenging?
Try launching from different heights or distances and see how it affects the results! You can also experiment with different types of launch objects.
