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. If more than one teacher from a school is sending
samples, you might want to create separate groups for each teacher.
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.
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.
|
 |
PERFECTLY
INTACT- (like it just left the factory) |
100 Points
|
|
 |
SLIGHTLY
DAMAGED - (cracked, but still in one piece) |
50 Points
|
|
 |
A CHIPPED
CHIP - (chipped along the edges less than 5 pieces)
|
10 Points
|
|
 |
A SPLIT
CHIP - (chip is broken into 2 fairly equal pieces)
|
10 Points
|
|
 |
SIGNIFICANTLY DAMAGED - (chipped and/or cracked less than 20
pieces) |
5 Points
|
|
 |
POTATO DUST
- (too many to count, more than 20 pieces) |
1 Point
|
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:
Intactness score (c)
OVERALL SCORE =
_________________________
[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
All scores should be reported to the
sending school using the following format:
1. Name of students, or
identification codes.
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

The Pringles Challenge Project addresses the National
Science Education Standards related to technological design.
ABILITIES OF TECHNOLOGICAL DESIGN
• IDENTIFY APPROPRIATE PROBLEMS FOR TECHNOLOGICAL DESIGN.
Students should develop their abilities by identifying a
specified need, considering its various aspects, and talking
to different potential users or beneficiaries. They should
appreciate that for some needs, the cultural backgrounds and
beliefs of different groups can affect the criteria for a
suitable product.
• DESIGN A SOLUTION OR PRODUCT.
Students should make and compare different proposals in the
light of the criteria they have selected. They must consider
constraints--such as cost, time, trade-offs, and materials
needed--and communicate ideas with drawings and simple
models.
• IMPLEMENT A PROPOSED DESIGN.
Students should organize materials and other resources, plan
their work, make good use of group collaboration where
appropriate, choose suitable tools and techniques, and work
with appropriate measurement methods to ensure adequate
accuracy.
• EVALUATE COMPLETED TECHNOLOGICAL DESIGNS OR PRODUCTS.
Students should use criteria relevant to the original
purpose or need, consider a variety of factors that might
affect acceptability and suitability for intended users or
beneficiaries, and develop measures of quality with respect
to such criteria and factors; they should also suggest
improvements and, for their own products, try proposed
modifications.
• COMMUNICATE THE PROCESS OF TECHNOLOGICAL DESIGN.
Students should review and describe any completed piece of
work and identify the stages of problem identification,
solution design, implementation, and evaluation.
