Rube Goldberg Project

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 6 steps. You must incorporate at least 3 out of 6 simple machines (wheel & axle, pulley, screw, inclined plane, wedge, and lever. )

Rules • • The end result is to put a bottle in the bin Work with up to 4 partners You chose the steps & materials Minimum 6 steps Must be repeatable (reset & run again) Must be brought into class (size limit) Should not spend more than $10, use 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 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.

Task #2 Build the Device • Construct a Rube Goldberg machine which utilizes 3 simple machines, and consists of at least 6 steps. • Your machine must complete the task of putting an empty water bottle in the recycling bin. • There can be no human assistance in the process once the machine begins.

Task #2 Build the device • The machine must be selfcontained. In other words, all of the parts must be present in the machine. Only the empty water bottle and the recycling bin will be provided.

Task #2 • Our classroom chairs, desks, and tables can’t be essential to your project. • In other words, if we took your project to the stage, 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, mousetrap, paper tube, spools, marbles, Legos, dominoes, tinker-toys, Barbie dolls, hot wheels, weights (sinkers), golf balls, Ping. Pong balls, pulleys, boards, boxes, springs, but NO LIVING PARTS.

Task #2 Due Date • Your completed machine must be completed and ready to share at our final meeting on May 20 th. • You will present your machine to the club, teachers, and judges.

Task #3 Presenting • You will explain & present your machine to the club, teachers, and judges. • You will then show your machine works. • We may video your machine! • Presentation day is May 20 th.

FAQ • Can I have a partner? – Yes you may have up to 4 partners, but choose wisely. You will need to meet together. If you want to do this project alone you may. • Where will we work on our machine? – You will need to plan and collect materials on your own – Our next club meeting will be the only “at school” time to work on your project – YOU MAY NOT LEAVE YOUR MACHINE AT SCHOOL! It must be broken down and taken home by your team.

Rubric • Blueprint A = Detailed & completely labeled project, all steps are labeled & explained, all simple machines are labeled. Neat, & Legible B = Completely labeled project, 90% of steps are labeled & explained, all simple machines are labeled C Project Is mostly labeled & explained, all steps are labeled & explained, all simple machines are labeled F = Project Labels are incomplete, or unclear

Machine Scoring 1. 2. 3. 4. 5. Human assistance –points subtracted Self-contained - up to 10 pts portability Completes a task - up to 10 pts 6 steps involved – pts added for more 3 different simple machines – pts added for more 6. Quality/Neatness – up to 30 pts 7. Creativity – up to 30 pts
