What Youโll Need:
- 7 popsicle sticks
- 3 rubber bands
- 1 plastic spoon
- Mini marshmallows (or small objects to launch)
Steps:
- Create the base: Stack 5 popsicle sticks together and secure both ends tightly with rubber bands.
- Make the launching arm: Take the remaining 2 popsicle sticks and place the spoon on top of one stick. Secure the spoon’s handle to the stick using a rubber band.
- Assemble the catapult:
- Insert the stack of 5 sticks between the two sticks of your launching arm to create a cross shape.
- Adjust the placement so that the spoon side extends out, creating leverage.
- Test it out: Place a mini marshmallow in the spoon, press the spoon down slightly, and release to launch!
๐ก STEM Learning Tip: Experiment with different placements of the sticks to see how it affects the distance and height of your launch. Encourage your child to predict and test their ideas!
