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 10 steps. You must incorporate at least 4 out of 6 simple machines (wheel & axle, pulley, screw, inclined plane, wedge, and lever.)
Rules
• The end result is to fill a cup• Work with one partner from your class• You chose the steps & materials• Minimum 10 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.– DUE: Monday, January 9, 2012DUE: Monday, January 9, 2012– No Late Work Accepted.No Late Work Accepted.– Worth 1 Lab Grade & 1 Daily GradeWorth 1 Lab Grade & 1 Daily Grade
Task #2Build the Device
• Construct a Rube Goldberg machine which utilizes six simple machines, and consists of ten steps.
• Your machine must complete a task, either filling a cup or putting a ball in a cup.
• There can be no human assistance in the process once the machine begins.
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 check out pulleys, and limited other materials from the science department.
Task #2 Due Date
• Your Completed Machine must be completed and turned in no later than the beginning of your class on Thursday, January 13, 2012.
• No late work will be accepted.
• This is worth 5 lab grades.
Task #3Presenting
• You will explain & present your machine to the class.
• You will then show how your machine works.
• BTW your machine will be videotaped!
• This is worth one lab grade.• Presentation day is Tuesday,
Jan. 17.
FAQ
• Can I have a partner?– Yes you may have a partner, but choose 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 daily grade?– Stay on task, no wandering, no being reminded
to stay on task = A– Talk to once = C– Have to be remained more than once = F
Rubric
• BlueprintA = 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. No human assistance 0-52. Self-contained 0-53. Attempts to complete a task 0-54. At least 10 steps involved 0-105. Uses at least 4 different simple
machines 0-156. Quality/Neatness 0-307. Creativity 0-30
