  1. Rube Goldberg Project Grade 8 Mechanical Advantage and Efficiency

  2. What is a Rube Goldberg Device? • Rube Goldberg drew contraptions that make simple tasks into difficult and complicated ones.

  3. Examples • http://autorepair.about.com/library/multimedia/hhonda-ad-300k.swf • http://www.break.com/index/best_rube_goldberg_ever.html • http://video.google.com/videoplay?docid=-2367646121273499414 • http://video.google.com/videoplay?docid=-3638354327358573516&q=&hl=en • http://video.google.com/videoplay?docid=-9133671200734505806&q=&hl=en

  4. 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.)

  5. 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

  6. Project Expectations • This project has three parts: • Blueprint • Build Device • Present Device in Class

  7. 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 25th, 2014

  8. 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!

  9. 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.

  10. 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.

  11. 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.

  12. 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

  13. 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

  14. 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

  15. 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.

  16. Machine Scoring • No human assistance • Self-contained • Only 1-2 attempts to complete thetask • At least 7 steps involved • Uses at least 4 different simple machines • Quality/Neatness • Creativity 0-30

  17. Procedure • Chose a purpose for your machine. • 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.

  18. 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.
