Rube Goldberg Challenge

Mini Design Challenge

Rube Goldberg Challenge

Your Challenge is to Build a
Rube Goldberg Machine with a Halloween Twist

Let’s get started! Your Halloween themed Rube Goldberg Machine must do something at the end. This could be to turn off a light, put candy in a cauldron, make a scary noise. Surprise us with something spooky! 
Your Rube Goldberg Machine should include:

  1. 8 Steps
  2. 5 Simple Machines
  3. 3 Energy Transfers in a Chain Reaction
  4. Name your Machine!
  5. Have Fun!
  • Plan your machine on paper or white board. You need 8 steps that do something spooky at the end.
  • Be creative
  • Include your simple machines
  • Look for how you can incorporate energy transfers (for ex: dominoes release kinetic energy as they knock the next domino and move to the next step. When a marble rolls, its’ gravitational potential energy is converted to kinetic energy. What is the marble rolling down? You guessed it, a simple machine.)
  •  Does your Rube Goldberg Machine contain a chain reaction? The dictionary says; A chain reaction is a series of events in which each event is the result of the one preceding and the cause of the one following.
  • Capture your Rube Goldberg Machine with pics or video. Contact Us to submit.

There are so many great examples of a Rube Goldberg Machine.
