Experimental Design

• Problem- What is the effect of the chip brand on
  the grease amount?
• IV Chip brand
• Levels of the IV Lays, UTZ, Krogers store
  brand, Wise
• Reason control was selected
• DV Amount of grease

3
Experimental Design

• Constants (3) Paper towel brand, regular flavor,
  amount of crushed chips
• Hypothesis If the chip brand is Lays then the
  grease amount will be greater, than the UTZ,
  Kroger store brand and, Wise.

Materials

• Chips
• Precisely 25 paper towels
• Ruler
• Permanent Marker
• Camera
• Table
• Stop watch
• Pencil
• Paper

5
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
  Krogers store brand
• On the remaining paper towel at the top write
  Lays

6
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
  Krogers 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.

11
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.

12
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)

13
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.
