Goals and Objectives
You have completed the final classroom test of Physics portion of 9th grade Science.
This project will test how well you can connect the material covered in class to your solution
to a real world challenge.
The use of creativity is required and desired!!
The challenge
• Each student or group will create a Rube Goldberg based machine or design of a machine that complete a simple task in the most complicated way imaginable.
• For Drama and Dance majors, an interpretation of a Rube Goldberg-based machine using your abilities will be considered by the teacher
Your project choices are
Create a 1) working machine that can be
demonstrated at school2) working machine that can be
videotaped in action at home3) a visual design of a machine
4) a different interpretation acceptable to Mr. Baker
New option continued
• Will have to connect your life to the concepts discussed in class just like the other groups and individuals
New option for period 7,5
Create “The day in your life” Rube
List 32 actions that happen to you over the course of a single 24-48 hour period
Each action is different from the other actions in some significant way
Option Three
If not doing either of the previous options, you must work on connecting concepts listed on the assignment sheet to your design or machine

the group’s efforts to produce the rube, from concept to final run. _______
A t least one connection to each of these concepts must described for full
credit1. An object that is accelerating by increasing
its speed2. An object that is accelerating by
decreasing its speed3. An object that is accelerating with
constant velocity4. An object with unbalanced forces,
resulting in a sliding motion5. Two examples of objects demonstrating
Newton’s first law, one not moving and one in motion.
6. Identification of at least 2 sets of action-reaction forces one set involving an object that is in motion, the other set involving something that is stationary
7. An object that is in free-fall for more than 1/10th of a second
8. An example of the conservation of momentum, where momentum is transferred from one object to another
9. An example where forces are applied to an object, but no work is done by those forces on that object.
10. An example where the KE of an object decreases as its GPE increases
11. An example where the GPE of an object decreases as its KE increases
12. An example where significant energy was transferred from one object to another through use of waves and where the receiving object changes its motion as a result
To get maximum credit for your Rube, you have to connect objects, actions or events that with the
following physical values1. The object obtaining the highest speed
2. The object or point in the rube that has the greatest number of different forces applied to it.
3. 3 different locations of frictional forces created by the contact of different materials
4. The object with the largest amount of inertia that moves during the operation of the rube
5. Determine which object has the greatest amount of momentum during the operation of your Rube
6. The force that does the greatest amount of work during the operation of the Rube
7. The force that produces the highest power rating
8. Identification of use of at least 4 out of the 6 simple machines in the operation of the Rube
10. The object undergoing the greatest displacement
11. The exact moment and location when an object has the most GPE during the operation of the rube
12. Identification of the moment and location when objects possess either chemical or electromagnetic energy
13. Identification of a medium through which a significant (noticeable) amount of energy is transmitted
14. Determine which object makes the sound with the highest pitch during operation of the rube
15. Determine which object makes the sound with the highest intensity during operation of the Rube
16. The exact moment and location when an object has the most KE during the operation of the rube
To get maximum credit for your Rube, you should be able to include in your rube, an example of at least 3 of
the following concepts:
1. Demonstration of use of all 6 simple machines at least once during operation of the Rube
2. Identification and use of at least one compound machine during operation of the Rube
3. Use of a machine with a mechanical advantage of greater than one during operation of the Rube
4. An object that demonstrates the Doppler effect
5. An object that achieves terminal velocity
6. Use of an object that visually demonstrates the interference of light
7. The use of sound waves to make an object move
8. Use an object with your favorite color and determine the frequency or frequencies of light that must be reflected into your eyes for you to see that color
9. Use of infrared, ultraviolet or microwaves to make something move and trigger the next step in the Rube
What is required from youVisual Presentation:
1) Minimum of 16 steps (all different)2) Use of variety of materials to create the presentation3) Style, Quality counts4) Theme (option)5) Connect concepts to the design6) Collect data based on your design7) Calculate physical values based on collected data8) Have a photograph taken of your finished design
Partners
• No partner on the visual design
• Can partner with one person on constructing a working rube machine
• Partner may come from any of my Physical Science classes
• All honors student groups graded at honors level
Physical Presentations
1) Minimum of 8 steps (all different)2) A mistake free run (live or videotaped)3) A variety of materials used4) Videotaped (no more than 10 minutes long) showing the
process of construction5) Theme (option)6) Connect concepts to the design7) Collect data based on your design8) Calculate physical values based on collected data
Features of Rube Machine
• Very simple task to be completed by machine
• Many intermediate stepsmore for the drawn design less for actual construction
• Most of the work will be done at home, not during class time
Limitations on choice of Actions or Steps
May not be derogatory to any individual or group
For the builders:1) candles are the only source of open flame allowed
(with parent permission)2) Nothing that is dangerous to yourself, others, or
the surrounding environment3) Additional limitations for those presentingin school
