Rube Goldberg Machine Project 2013 Purpose: Your Rube Goldberg machine must do one of the following tasks: Turn on a light bulb Pour a drink Sharpen a pencil Put tooth paste on a tooth brush Adhere a stamp to a letter Put a lid on a ball jar Toast a slice of bread Unlock a padlock (combination or key) Select, clean, and peel an apple Screw a light bulb into a socket Make a cup of coffee Turn on a radio Put coins in a bank Insert, and then play a cd disk Shut off an alarm clock Set up a golf tee and tee up a golf ball Secure, raise and waive the U.S. flag Design: Your machine must include a minimum of 15 steps to a maximum of 20 steps from start to finish. Each step must utilize some principle of physics. Maximum dimensions are: width 0.75m, x length 1.0 m x height 1.0 m. For safety reasons, you may not use flames, chemicals, or other hazardous materials. Your design should not include any offensive materials or themes. Your machine cannot be plugged into an electrical outlet to operate (dc only), nor can it include live animals. Physics: Your machine should illustrate principles of physics. It needs to use at least 5 principles of mechanics, 1 principle of sound, 1 of waves, 1 principle of electricity and 1 of magnetism. You will need to describe in detail, these principles in a written report that you submit along with your project. Construction:Your machine should be constructed from materials that you scrounge from home or family or friends or work. Total cost of the machine should not exceed $10.00 per group. Plan to put the pieces together with nails, screws, brackets, wood glue, hot glue, or some fasteners other than tape. No duct tape!!! You must also clearly number each step within your machine. Your final product should be sturdy, transportable, and professional looking. Operation: Your machine needs to be reliable. In other words, once you start the first step, the remaining steps should follow without human intervention. In addition, you should be able to reset the machine quickly for another run. You will be given 3 runs on your machine. Scoring will be based on the number of successful steps during the operation of your machine. EACH STEP MUST BE DIFFERENT FROM THE PREVIOUS STEP, BOTH IN PRINCIPLE AND ACTION. Schedule / Time Table: Your project presentations will be scheduled as follows:

Wednesday, March 20, 2013 Submit names of the members of your group and the task you have chosen for your machine.

Wednesday, April 17, 2013 Written reports are due (5th six weeks project grade)

Wednesday- Friday May 15-17 Oral presentations are due

Wednesday- Friday May 22-24 Machine demonstrations begin Written Report: Although you will need to explain the physics of your machine when you present it to the class, it is in the written report that you will provide the details of the physics principles you used. This report should include detailed description of the physics principles that apply to each step in your machine, along with a detailed description of what happens in each step. The report will also include a listing of the principles used in each of the specified categories: mechanics, sound and waves, electricity and magnetism. Report Format: Title Page: 1) Alphabetical listing of team members 2) task accomplished 3) class period 4) date of oral presentation 5) Date of machine demonstration

6) Teacher’s Name Introduction: 1) Brief explanation of your project 2) purpose3) number of steps Materials list: provide a list of all materials used to complete the task. Description of the physics used: A written description of each principle, also include any appropriate drawings or diagrams to better emphasize each process. Description of each step: A written description of each step in sequence. You might also want to include a drawing or picture (photos are allowed) of each step. Summary of project: Summarize the project, bring the report to a close.

Grading: Your overall grade on your Rube Goldberg Machine will be based on: The machine itself Your written report Your oral presentation The cumulative average 1. The machine: You will be given three attempts to demonstrate your machine. You will receive 2 points for each successful step completed during the operation of your machine. Example 1: Your machine has 15 steps and... attempt 1 only 12 steps function properly 24 points attempt 2 successful at all attempts 30 points attempt 3 only 10 steps function properly 20 points total 74 points Example 2: Your machine has 20 steps and... attempt 1 only 15 steps function properly 30 points attempt 2 successful at all attempts 40 points attempt 3 only 17 steps function properly 34 points total 104 points 2. The Written Report (5th six weeks): Your written report should follow the guidelines described above. Completeness and quality of explanations should be stressed. All appropriate diagrams, pictures, etc., should be included. You must submit your written report on the due date. Late reports will lose 10 points per day. This report must be typed (20 point deduction for hand written papers) (drawings and diagrams may be hand drawn).

Total possible points 100 This will be worth 2 test grades the fifth six weeks.

3. The presentation: Your group is responsible for presenting your project to the class. a) The presentation should be at least 10 minutes in length. You may use media apparatus available. Power point presentations are permitted. Video is permitted but cannot be utilized for more than 3 minutes of the total presentation. b) You must have at least one visual aide to use during your presentation. c) You must have at least one handout to be given to each student and instructor in the class. d) All group members must actively participate in the presentation. e) Be prepared to answer questions about your machine

length of presentation 10 points use of visual aide 10 points appropriateness of handout 10 points all group members actively involved 10 points ability to answer questions 10 points quality of overall presentation 50 points total possible 100 points

4. Cumulative average: This grade is an overall score for the project. it is worth 3 test grades the final six weeks. Machine grade score possible 90-120 points Written report score possible 100 points Oral presentation score possible 100 points total = ???????? Average = ???? / 3 = final score

NO MOUSETRAP GAMES!!!!
