=Welcome to the **Pringles Challenge of Spring 2009** between Kaffie Middle School in Corpus Christi, Texas and Henderson Middle School in Richmond, VA.=

Here are the guidelines from the official Pringles Challenge site:

**OBJECTIVE:**

For students to design and test a container for shipping a single Pringles ™ potato chip, via the US Postal Service. The participating schools will match up via this web page. Students will exchange packages with schools somewhere in the United States. Upon arrival the packages will be evaluated and scored using the format in the scoring section.


 * GOAL:**

To engineer the package to have the smallest volume and smallest mass that will protect the chip so that it arrives at its destination undamaged.
 * RULES AND REGULATIONS:**

1. Students will use 1 (regular) Pringles potato chip. 2. No substance may be applied to the chip, or the chip altered in any way. 3. The chip must be recoverable and edible ( but don't eat them!!!!)  when received by the evaluating school. 4. Students will work individually or in small groups on the design, building and testing of this project. 5. All packages must be sent via the US Postal Service - First Class Mail! (please be aware the there may be a surcharge for small packages if you stamp them yourself. It may be advisable to bring them to the post office for stamping!) **Packages sent using any other carrier will be disqualified. ** 6. (Also be advised that there is a 3" x 5" limit on the size of the package, and a fussy postman may reject a smaller package. However in the past many, many packages smaller that 3" x 5" have been delivered, so getting a small package through the mail is part of the challenge). 7. Package must be clearly labeled on the outside with the sending school and group. (if special unpacking instructions are needed they should also be included). 8. Each participating school will send, receive and evaluate packages. 9. Each package must be clearly labeled "PRINGLES CHALLENGE" and addressed to the receiving school, in care of the particular teacher. 10. The sending school MAY write only "Fragile" or "Handle With Care" on the package. 11. It is the responsibility of individual teachers to assure that results are accurate, and that they are exchanged in a timely manner.


 * PRINGLES SCORING:**

The following measurements must be made by the receiving / evaluating team: a. Mass of the package in Kg's to at least 3 [|significant figures]. b. Volume of the package in cubic centimeters to at least 3 [|sig. figures]. c. Intactness score of the chip must be determined from the following scale and awarded by the evaluating school. d. OVERALL SCORE: The overall score for a package will be the one used to determining the winners. This score will be calculated using the following equation:
 * [[image:http://www.gatesscience.info/teamescience/images/tater.gif width="100" height="100"]] || PERFECTLY INTACT- (like it just left the factory) || 100 Points ||
 * [[image:http://www.gatesscience.info/teamescience/images/tater/tatercr.gif width="100" height="100"]] || SLIGHTLY DAMAGED - (cracked, but still in one piece) || 50 Points ||
 * [[image:http://www.gatesscience.info/teamescience/images/tater/taterch.gif width="100" height="100"]] || A CHIPPED CHIP - (chipped along the edges less than 5 pieces) || 10 Points ||
 * [[image:http://www.gatesscience.info/teamescience/images/tater/tatertwo.gif width="100" height="100"]] || A SPLIT CHIP - (chip is broken into 2 fairly equal pieces) || 10 Points ||
 * [[image:http://www.gatesscience.info/teamescience/images/tater/tatermore.gif width="100" height="100"]] || <span style="color: rgb(0,0,0);">SIGNIFICANTLY DAMAGED - (chipped and/or cracked less than 20 pieces) || <span style="color: rgb(0,0,0);">5 Points ||
 * [[image:http://www.gatesscience.info/teamescience/images/tater/taterdust.gif width="100" height="100"]] || <span style="color: rgb(0,0,0);">POTATO DUST - (too many to count, more than 20 pieces) || <span style="color: rgb(0,0,0);">1 Point ||

OVERALL SCORE = Intactness score (c) / [mass in Kg (a) x volume in cc (b)]

Example: a. mass = 0.145 kg b. volume = 240 cc c. intactness score = 100 (perfect chip) d. OVERALL SCORE = (c) 100 / [(a) 0.145 kg x (b) 240 cc] So (d) OVERALL SCORE = 2.87
 * REPORTING SCORES:**

<span style="color: rgb(0,0,0);">All scores should be reported to the sending school using the [|following format]: 1. Name of students, or identification codes. <span style="color: rgb(0,0,0);">2. Date package was received and condition. 3. Mass in Kg (3 sig figs) [(a) from scoring] 4. Volume in cubic centimeters (3 sig figs) [(b) from scoring] 5. Intactness score awarded [ (c) from scoring] 6. OVERALL SCORE (3 sig figs) [ (d) from scoring] 7. Additional teacher comments 8. Additional student comments
