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.

The Rube Goldberg Project
•Goal:–You must design & build a Rube Goldberg Device that has 7 steps. You must incorporate at least 4 out of 6 simple machines (wheel & axle, pulley, screw and inclined plane, wedge, gear, 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 three parts:–Blueprint–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, screw and inclined plane, wheel and axle, gear, wedge,pulley.– Presentation is due Tuesday March 25Presentation is due Tuesday March 25thth, ,

Task #2Build 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 (moving a can 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… .
• Tuesday March 25th, 2014
Task #3Presenting
• You will explain & present your machine to the class.
• You will then show how your machine works.
• Presentation day is … • Tuesday Mar 25th, 2014
FAQ
• Can I have a partner?– Yes you may work in groups of 2 or less, but
choose partner wisely. If you want to do this project alone you may.
• 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– Follow guidelines and make an awesome project
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 labeled.
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 1-2 attempts to complete
thetask 4. At least 7 steps involved5. Uses at least 4 different simple
machines6. Quality/Neatness7. Creativity 0-30
ProcedureProcedure
1. Chose a purpose for your machine.
2. Design and illustrate your Rube Goldberg Machine Poster on a Letter Size or Poster Size 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.
Procedure cont’d
4. Describes simple machines that are required in the design (pulleys, levers, etc.)
5. Label the forms of energy (PE. KE, etc…).
6. A presentation will be made to the class: Explain all steps.
Identify all simple machines. Identify all forms of energy.
