  • Rube Goldberg Project

    Grade 8

    Mechanical Advantage and Efficiency

  • What is a

    Rube Goldberg Device?

    • Rube Goldberg drew contraptions that make simple tasks into difficult and complicated ones.

  • Examples

    • dia/hhonda-ad-300k.swf

  • The Rube Goldberg


    • Goal:

    –You must design & build a Rube Goldberg Device that has 7 steps. You must incorporate at least 5 out of 6 simple machines (wheel & axle, pulley, screw, inclined plane, wedge, and lever.)

  • Rules

    • The end result is to move a can

    • Work with one partner from your class

    • You choose the steps & materials

    • Minimum 7 steps

    • Must be repeatable (reset & run again)

    • Must be brought into class (1.5mx1.5m)

    • Use recycled/repurposed “stuff” from around

    the house

  • Project Expectations

    • This project has four parts:



    –Build Device

    –Present Device in Class

  • Task #1

    Blue Print

    • Create a blueprint (cartoon drawing) of your machine.

    • Number each step of your machine.

    • On the bottom or the back of your drawing, explain each step.

    • Also, list the simple machines that you used. Simple Machines: lever, inclined plane, wheel and axle, screw, wedge, pulley.

    – Presentation is due on…

  • Task #2

    Build the Device

    • Construct a Rube Goldberg machine which

    utilizes six simple machines, and consists of a

    minimum of 7 steps.

    • Your machine must complete a task, either

    moving a can, filling a cup or putting a ball in

    a cup.

    • There can be no human assistance in the

    process once the machine begins.

    • Alternate tasks must be approved!

  • Task #2

    Build the device

    • The machine must be self-contained. In

    other words, if you are turning on a

    light switch, you will not be allowed to

    use the classroom's light, so you must

    bring in your own switch.

  • Task #2

    • The classroom chairs, desks, and tables can’t

    be essential to your project.

    • In other words, if we took your project to the

    next room, it would work the same.

    • Also, you cannot be part of the machine. For

    example, you can’t hold pulleys in the air.

    They must be attached.

  • Possible Materials

    • Possible Materials: string, candle, mousetrap, paper tube, spools, marbles, Legos, dominoes, tinker-toys, Barbie dolls, hot wheels, weights (sinkers), golf balls, Ping-Pong balls

    • You can use premade pulleys if necessary, but remember imagination and creativity is key.

  • Task #2 Due Date

    • Your Completed Machine must be

    completed and turned in no later than

    the beginning of your class on… .

  • Task #3


    • You will explain & present your

    machine to the class.

    • You will then show how your machine


    • Presentation day is …

  • FAQ

    • Can I have a partner?

    – Yes you may work in groups of 2-3 or less, but choose partner wisely. If you want to do this project alone you may. A strong group will likely have an artist, a designer and a writer.

    • What happens if I am absent?

    – Being absent does not excuse you from the project. Have a friend bring the project to school for you.

    • How do I get a good grade?

    – Stay on task, no wandering, no being reminded to stay on task = A

  • Rubric

    • Blueprint

    4 = Detailed & completely labeled project, all steps

    are labeled & explained, all simple machines are

    labeled. Neat, & Legible.

    3 = Completely labeled project, 90% of steps are

    labeled & explained, all simple machines are


    2 = Project Is mostly labeled & explained, all steps are

    labeled & explained, all simple machines are labeled

    1 = Project Labels are incomplete, or unclear.

  • Machine Scoring

    1. No human assistance

    2. Self-contained

    3. Only 1attempt to complete the task

    4. At least 7 steps involved

    5. Uses at least 5 different simple machines

    6. Quality/Neatness

    7. Creativity 0-30

  • Procedure

    1. Chose a purpose for your machine.

    2. Design and illustrate your Rube

    Goldberg Machine Poster on a 81/2’

    x11’ or 14’x11’ blank paper

    Title should be short and bold.

    Steps should be clearly labeled with

    numbers or letters

    3. Write the steps on a separate sheet

    of paper using a graphic organizer (“T”

    chart) and tape it to the back of the


  • Procedure cont’d

    4. Describes simple machines that

    are required in the design (pulleys,

    levers, etc.)

    5. Label the forms of energy (PE. KE,


    6. A presentation will be made to the

    class: Explain all steps.

    Identify all simple machines.

    Identify all forms of energy.
