Jumping Joey: A Fun Engineering Project for Elementary Kids

SchoolTube: Jumping Joey – A Fun Engineering Project for Elementary Kids

Welcome to SchoolTube, where learning meets fun! In this blog post, we’ll take you on an exciting journey as we explore the world of physics and engineering through a captivating project called “Jumping Joey.” This DIY STEM activity is perfect for elementary-aged kids and promises to ignite their curiosity and creativity.

What is Jumping Joey?

Jumping Joey is a clever little contraption that can jump rope all by itself! It’s a fantastic way to introduce young minds to the concepts of pivot points, gravity, and simple machines. By constructing Jumping Joey, kids will gain hands-on experience with these scientific principles and develop a deeper understanding of how things work.

Materials Needed:

  • Cardboard tube (from a paper towel roll or similar)
  • String or yarn
  • Scissors
  • Tape
  • Straw
  • Paper clip
  • Rubber band
  • Decorations (optional)

Step-by-Step Instructions:

  1. Prepare the Cardboard Tube: Cut the cardboard tube in half lengthwise.
  2. Attach the String: Tape one end of the string to the inside of one of the cardboard tube halves, near the top.
  3. Create the Pivot Point: Insert the straw into the center of the paper clip and tape it in place. Then, tape the paper clip to the other cardboard tube half, directly across from the string.
  4. Attach the Rubber Band: Stretch the rubber band around the two cardboard tube halves, connecting the pivot point and the string.
  5. Add Decorations: (Optional) Let your child decorate Jumping Joey to make it their own.

How it Works:

When you pull the string, the rubber band twists and stores energy. As you release the string, the energy is released, causing Jumping Joey to jump up and down. The pivot point allows Jumping Joey to move freely and jump with ease.

Learning Opportunities:

  • Physics: Jumping Joey demonstrates the principles of force, motion, and energy.
  • Engineering: Kids apply engineering concepts as they design and construct Jumping Joey.
  • Creativity: Children can express their creativity by decorating Jumping Joey.
  • Problem-Solving: Troubleshooting and making adjustments to Jumping Joey encourages problem-solving skills.


Jumping Joey is an engaging and educational project that brings together science, engineering, and creativity. By following these simple steps, elementary-aged kids can create their own Jumping Joey and explore the wonders of physics and engineering. So, gather your materials, let your child’s imagination soar, and jump into the world of STEM learning with SchoolTube!
