How greasy are your
potato chips?
By: Dharma Shrecengost
Experimental Design
 Problem- What is the effect of the chip
brand on the grease amount?
 IV: Chip brand
 Levels of the IV: Lay’s, UTZ, Kroger’s
store brand, Wise
 Reason control was selected:
 DV: Amount of grease
Experimental Design
 Constants (3) :Paper towel brand,
regular flavor, amount of crushed
chips
 Hypothesis: If the chip brand is
Lay’s then the grease amount will be
greater, than the UTZ, Kroger store
brand and, Wise.

Procedures
 Gather Materials
 Place five paper towels beside each other on a table
 Write one name of the listed potato chip brands per
paper towel
 On one paper towel on the top write UTZ
 On the next paper towel on the top write Wise
 On the next paper towel at the top write Kroger’s
store brand
 On the remaining paper towel at the top write Lay’s
Procedures (continued)
 Open each chip bag (package)
 Place two chips into their correctly labeled
paper towel
 Make sure the chips are equally leveled on the
paper towel
 Turn the stop watch on
 After 10 minutes have gone by, remove the
chips from the paper towels
 Measure grease spots with a ruler in cm
 Record and compare all data
 Repeat steps five times for accurate results

Discussion –
The results concluded that Utz had the most
grease of the chips tested. The average of Utz was
23.8, the average of Wise was 22, the average of
Lays was 20.8 and, the average of Kroger’s store
brand was 16.2.
The research concluded that there are regular,
kettle-cooked, baked and air-popped potato chips, as
well as potato crisps. These potato chips all have
varied amounts of grease depending on the cooking
methods. Usually, baked and air-popped chips should
have the least amount of grease, with regular and
kettle chips having the most.
Conclusion
 Hypothesis: If chip brand is Lays,
then grease amount will be higher.
 Hypothesis was rejected , because the
chip brand (Lays) had a lower amount
of grease than the Utz and Wise.
Conclusion (continued)
 Errors made included: Size of chip
 If done differently: I would use
differently textured chips along with a
different flavor (ex. Sour cream &
onion)
Conclusion (continued)
 Overall, this science experiment was a
success, because I accurately
measured the grease of the chips and
had all the chips begin and end at
approximate the same time.
