1 How greasy are your potato chips? By: Dharma Shrecengost
2 Experimental DesignProblem- What is the effect of the chip brand on the grease amount?IV: Chip brandLevels of the IV: Lay’s, UTZ, Kroger’s store brand, WiseReason control was selected:DV: Amount of grease
3 Experimental DesignConstants (3) :Paper towel brand, regular flavor, amount of crushed chipsHypothesis: If the chip brand is Lay’s then the grease amount will be greater, than the UTZ, Kroger store brand and, Wise.
5 Procedures Gather Materials Place five paper towels beside each other on a tableWrite one name of the listed potato chip brands per paper towelOn one paper towel on the top write UTZOn the next paper towel on the top write WiseOn the next paper towel at the top write Kroger’s store brandOn the remaining paper towel at the top write Lay’s
6 Procedures (continued) Open each chip bag (package)Place two chips into their correctly labeled paper towelMake sure the chips are equally leveled on the paper towelTurn the stop watch onAfter 10 minutes have gone by, remove the chips from the paper towelsMeasure grease spots with a ruler in cmRecord and compare all dataRepeat steps five times for accurate results

9 Graph (Averages) of The Grease Spot Measurement Average Brand Name of Chips
10 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.
11 ConclusionHypothesis: 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 chipIf 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.
