Product Information


Push, pull, and play your way to understanding force. Experiment with air pressure, discover simple machines in everyday items, and design your own incredible invention! In this physics curriculum kit, your young engineer will explore balanced and unbalanced forces with air pressure, learn about potential and kinetic energy, make simple machines, and create an exciting invention.

This Accelerate level kit includes a full-color student workbook and a detailed teacher guide, with step-by-step instructions for both hands-on and reading-based activities designed to engage students in forces, motion, and the engineering process. Both teacher and student will be able to open the box and start within minutes, and the kit will provide over 14 hours of engaging learning.

In this kit, the student will engage in these fun activities:

  1. Using only the power of air, try to keep a ball in the air.
  2. Find out how different forces affect the motion of an object.
  3. Explore how balanced and unbalanced forces can move other objects.
  4. Discover simple machines in everyday life that help us complete tasks more easily.
  5. Find some inspiration to create an incredible invention that completes a simple task.

Your student is ready for this kit when:

  • They have learned about forces in terms of push and pull.
  • They are curious about how things move.
  • They are interested in building, designing, or inventing things.

Use the Funny Forces kit to answer questions such as:

  • How do balanced and unbalanced forces affect the motion of objects?
  • Can I predict the motion of objects?
  • Does gravity affect all objects the same?
  • What is a simple machine?
  • Who or what is Rube Goldberg?

Our Funny Forces kit is a part of the Science Unlocked Accelerate series and is recommended for elementary and middle school students in grades 3-7. Prior to completing Funny Forces, we recommend the prerequisite kit Blast Off!
