Rube Goldberg ProjectDUE TUESDAY, OCTOBER 22ND!!

Learning Objective:

  • Use yourresearch-based knowledge of simple and compound machines to design and build a small Rube Goldberg machine.

(Log onto to view a variety of Rube Goldberg Machines)

Introduction:

We have been learning about simple and compound machines, calculating mechanical advantage and thinking about machines as a part of society. What is a simple machine? A simple machine makes work easier for people.

Sometimes designing a silly, round-about way to do something can enable one to better understand the inner details of the more practical, direct solution. Whenever a machine is made too complicated to do a simple job, it is called a “Rube Goldberg”.

Assignment Overview:

For this assignment, you may work alone or with a partner, but it is important to note: MOST OF THE WORK ON THIS PROJECT WILL BE SPENT OUTSIDE OF CLASS! If you choose to work with a partner, pick a partner you will be able to work with outside of school.

In this activity, you will research Rube Goldberg and simple machines, and design and build your own Rube Goldberg machine. It is your mission to construct a machine that uses at least 6 individual steps/stages to complete a simple task like one of the following:

  • TURN ON A LIGHT BULB
  • STAPLE TWO PAPERS TOGETHER
  • FILL UP A DIXIE CUP WITH WATER
  • POP A BALLOON

Your machine will take some time to put together. You will have a few days of in-class time to learn how to research, plan, and build this machine. You may use almost any object that you can find. You are limited to “safe” things. No flammable items or chemicals are permitted. Here are a few ideas:

  • Cardboard
  • Paper Clips
  • Tape
  • Construction paper
  • String
  • K’nex or Legos
  • Sand
  • Plastic Containers
  • Wood
  • String
  • Nuts and bolts

Assignment Guidelines:

There are three components to this project. Grading criteria is as follows:

  • Complete 1 Section to level 4 standards: up to 77%
  • Complete 2 Sections to level 4 standards: up to 85%
  • Complete all 3 Sections to level 4 standards: up to 100%

Section 1:

You will compile research in the form of a typed 2 to 3 page paper or a PowerPoint/other media presentation.

  • You will research Rube Goldberg and the machines he created.
  • You will find a video, illustration, or photo of an example of a Rube Goldberg machine that you enjoyed learning about.
  • You will research the 6 simple machines, using graphics to represent each.

Section 2:

You will create a “blue print” or draft of your own original Rube Goldberg apparatus. This blue print will include:

  • A drawing or sketch that is an accurate representation of your apparatus.
  • The steps listed in order, numbered and labeled on the drawing, photo, or sketch.
  • All parts labeled, showing each simple machine component.
  • Neatness, organization, and effort.
  • A MINIMUM of 6 machines (at least one of each simple machine).
  • A MINIMUM of 6 steps. An “A” project will have 10 steps.
  • DEFINITION OF A STEP: A single step is defined as a transfer of energy, or 1 cause through 1 effect.
  • EXAMPLES OF STEPS: 1. Ball rolls down a ramp and springs a mousetrap. 2. The mousetrap pulls a string causing a scissors to cut. 3. The scissors cut a cord, causing a weight to fall. 4. Weight drops on tin foil, causing light bulb to turn on.
  • Your machine must have a theme. EX: a favorite movie, animal, a room in your house, something science related, etc.

Section 3:

You will construct your Rube Goldberg apparatus and present it to your peers in a small group setting. Your apparatus must meet the following criteria:

  • It must be small enough to fit on a lab desk or table, be able to fit through the door, and not take up an extremely large amount of space.
  • It must be well constructed, so it does not fall apart and it is made with high quality craftsmanship. This means it should be evident that great effort was put into the constructed presentation.
  • It must be in working condition, with the ability to complete its task consistently (not just once and then it falls apart).
  • It must have a minimum running time of 10 seconds, and a maximum run time of 5 minutes.
  • See all guidelines in Section 2 for defining STEPS and theme.
  • If your machine fails to work on its first graded attempt, you are allowed one free restart, which must occur within five minutes of the first run.
