Some potato chips are not really potato chips at all. Pringles TM are an example of this. Pringles are made from potato flakes that are combined with rice flour to make potato dough. The dough is then shaped and fried. Since Pringles are not made only of potatoes, they are called potato crisps. One thing that some people think about when buying potato chips and potato crisps is the amount of fat in them. Although eating fats is necessary for your body to function, eating too much fat is not good for you.
Children older than 2 years old should get 30 percent of their daily calories from fat. Many people get more than that, which is why there are many kinds of reduced fat potato chips and potato crisps available in stores. In this cooking and food science fair project, you will investigate how much fat is in some typical potato chips and potato crisps products.
You will take a look at four different kinds of chips and crisps: kettle-fried potato chips, baked potato chips, Pringles Original potato crisps, and Pringles Reduced Fat potato crisps. Have fun, but be sure not to not eat your science fair project before you are done! What was the most important thing you learned? Our favorite chips were the greasiest.

Science Buddies Staff. Accessed 11 Nov. Introduction Do you like to snack? Terms and Concepts Fat Calorie Estimate Questions Can you estimate how many chips you and your friends eat in one week? What is the difference between a potato chip and a potato crisp?
What is fat? Should people get rid of all the fat they eat? Bibliography Kleiman, D. My Chip is Better than Your Chip. The New York Times. How do your fingers look? Can you see some shiny grease on them? How do your fingers feel when you rub them against one another? After washing and thoroughly drying your hands, repeat the first and second steps with the reduced-fat chips.
Do they look very different? Are your hands less greasy after you crumble them with your fingers? Take the pile of regular chips that you prepared and spread them evenly on the graph paper so the whole area is covered with chips.
Carefully press down on the wax paper and crush the chips. Try to keep the pieces evenly spread out on the graph paper. Use the rolling pin to crush the chips into smaller pieces. Set your timer for one minute, and let the crushed chips sit on the graph paper for the full minute. After the minute has passed, put the wax paper and the potato chips into the trash. Try to remove all of the extra chip bits from the graph paper, too. Do you notice a grease stain on the graph paper?
How large is the grease stain? Tape the graph paper to a well-lit window so you can see the stain clearly; let it hang there for about 10 minutes. How much of the graph paper is covered in grease? Are there any areas that are not translucent? What are the sizes of the individual grease stains on the graph paper? Also look at the regular sheet of paper that was underneath the graph paper. Did any of the grease spots leak through the graph paper? How many grease spots do you see on this sheet of paper?
Repeat steps 4 through 10 with the reduced-fat chips. How does the grease spot on the graph paper look this time? Is more or less area of the graph paper covered with grease?
What do you notice when you compare the sizes of the individual grease spots with the spots left by the regular chips? On the underlying sheet, do you count more or fewer grease spots?
Finally, look at the nutrition labels on both bags of potato chips. How much fat is in each of them? Do these numbers agree with your grease spot results? Extra: As you look at the grease spots on the graph paper, try to count all the squares that are covered in grease; this way you also have a quantitative measurement of the fat content in the two different potato chip varieties.
Compare the results for both of the chip varieties. Did you expect these results? How many more squares were covered in grease using the regular chips compared with the reduced-fat ones? Extra: Often foods with reduced fats have additional ingredients to take the place of the missing fats.
Examine the labels of the two bags of chips. Sorry, no Branches found. Please select here to find all our stores. See our full list of stores. Already have an account? Monthly Specials. Trade Terms.

Packaging When food delivery apps like UberEATS, Deliveroo and Foodora came on the scene a few years ago, fast food outlets were struck with a challenge.
