RUBE GOLDBERG

DUE DATE (THURSDAY MAY 25th)

Project Introduction:

In this unit you have learned about the types of forces, motions, and relationships between them. This all is stated in Newton’s laws of motion that we have studied throughout this unit.

Rube Goldberg was a cartoonist who is famous for his drawings of marvelous inventions that did simple things in a complex fashion.

What do I need to submit?

  • Original Sketch (Individual –rough drawing of how you in vision your machine)
  • Final Sketch (What you actually built) (Also needs to include a step by step process of how your machine works. Including Newton’s 3 Laws of Motion)
  • Completed Rube Goldberg Machine (3 simple machines and 5 steps)
  • Speed Calculations (Include 3 trials)

How do I make a Rube Goldberg Machine?

You will be working in a group of 2 or by yourself in order to complete this machine.

Your machine must complete a simple task. For example, your machine can:

  • Pour water into a cup
  • Shut off an alarm clock
  • Ring a buzzer
  • Hit play on your I-Pod
  • Put coins into a bank

Things that you can use:

  • Pulley* Balloons
  • Marbles* Wooden Sticks
  • PVC Pipe* Cardboard
  • Thread/String/Rope* Tape
  • Rubber Bands* Paper Cups

You can use other supplies just make sure that you have them approved with your teacher first. Everything must be completed in class.
