2015 Rube Goldberg Project Guidelines
Objective:
Each student or group of students will construct a Rube Goldberg machine consisting of consecutive
energy transfers that will result in Erasing a Chalkboard or Whiteboard.
Who was Rube Goldberg and what is a Rube Goldberg Machine? Rube Goldberg (1883 – 1970) was a Pulitzer Prize winning cartoonist, sculptor, and author. Goldberg
became renowned for creating absurdly connected machines that functioned in extremely complex and
roundabout ways in order to accomplish a very basic task. While most machines made complex tasks
much simpler, Goldberg’s inventions worked in reverse – transforming a simple task into a complicated
sequence of energy transfers.
Requirements: 1. You may work alone or in groups of up to three people to construct your Rube Goldberg machine.
2. If you work alone or in a pair, your machine must consist of at least seven (7) distinct energy
transfers that lead to the final step of Erasing a Chalkboard or Whiteboard. If you work in a group
of three, you must utilize ten (10) distinct energy transfers. While these are the minimum
requirements, you are encouraged to do more.
3. Erasing a Chalkboard or Whiteboard will entail mechanically erasing a word number or drawing that
fills (50% or more coverage) a 2in × 4in area on the chalkboard/ whiteboard. Creativity and
appropriate humor is encouraged with regard to the content your machine erases.
a. Whiteboard material is available at many local stores for purchase (Home Depot,
Michaels, etc). Classroom whiteboards can be used as well, but not taken from room.
4. Teams will be given 3 attempts to accomplish the task on the day of the testing. For each trial that
fails, 3 points will be deducted from the score.
5. In addition to the completion of the basic task, your group must produce a step-by-step explanation
of your Rube Goldberg machine. Explanations should include schematic drawings or digital pictures
depicting each energy transfer and the setup of your machine. While the explanations and drawings
will not be graded based on artistic ability, they should clearly explain and depict the energy
transfers occurring and be professional in nature.
6. In order to keep your group on track, you must submit a rough version of your step-by-step
explanation by Thursday, December 18, 2014 as a progress check.
7. The testing of the machines will take place on January 15, 2015 during class in room 181.
Therefore you must set up the machine either before class (in the morning or the previous
afternoon) or during class.
8. All machines will also be judged for originality, design and entertainment.
a. A vote will be held to decide which machine has the overall best design or theme
b. A vote will be held to decide the single most original energy transfer across all machines
c. A vote will be held to decide the most entertaining machine overall
Grading: At least 7 energy transfers (10 for trios) 40 points (1 extra point for each additional energy
transfer)
Successful completion of task 9 points (3 point deduction for each failed trial)
Step-by-Step Explanation with diagrams 31 points
Progress Check 20 points
Total 100 points (plus any bonus points)
Three Bonus competitions a. Best design/theme—Vote b. Most original energy transfer—Vote c. Most entertaining overall—Vote
Each bonus competition can earn you 5 bonus points, and these points can be added even if they increase your score beyond the perfect 100 points (These are the most valuable bonus points to get)
Action-Day Performance Rubric
Qualifying Energy Transfers (40+ points) If you work alone or in a pair, your machine must consist of at least seven (7) distinct energy transfers
that lead to the final steps of hammering the nail. If you work in a group of three, you must utilize ten
(10) distinct energy transfers. While these are the minimum requirements, you are encouraged to do
more.
Clarification on the descriptions used for a single “distinct energy transfer”
Must be documented in the Step-by-Step Explanation handed in on Action-Day
Kinetic energy is transferred by some means from one object to another
Ex: A falling baseball lands in a cup that pulls on a string…
o If electrical systems are used (it is encouraged for diversity) an isolated electrical
component can only count for a maximum of two transitions: an input and output
Input example: a level lowers on to an electrical button
Output example: a motor (turned on by the button) pulls a string
o Repeating series
A locally repeating process counts as one object with two transitions: an input
and an output (Ex: a series of dominoes counts as one object, with an input to
start the first domino to fall, and an output the last domino causes to happen)
Any energy transition can only qualify once and, if repeated elsewhere in the
machine, will only be counted once.
Erasing a Chalkboard or Whiteboard will entail mechanically erasing a word number or drawing
that fills (50% or more coverage) a 2in × 4in area on the chalkboard/ whiteboard. Creativity and
appropriate humor is encouraged with regard to the content your machine erases.

Successful Completion of Task (15 points) Teams will be given 3 attempts to accomplish the task on the day of the testing. For each trial that fails, 5 points
will be deducted from the score. A smiley will be drawn at your successful attempt below.
