Foods Containing Fats

1. Foods ContainingFats By: Lauren Foster

2. I picked this Science Fair Project because I thought it would be interesting to know what I am eating. I also picked it to know what I should eat, what is healthy, and what is not healthy. Big Question How much fats and oils are in the following foods: • Butter • Yogurt • French Onion Dip • Peanut Butter • Raw Bacon • Avocado • Potato Chip • Chocolate Chip Cookie

3. Hypothesis: I think… • Raw Bacon • Peanut Butter • Butter • Potato Chip • Chocolate Chip Cookie • French Onion Dip • Avocado • Yogurt 1 meaning most fats and 8 meaning least fats

4. Interesting Facts • The first cookies were created by accident. • Cooks used a small amount of cake batter to test their oven temperature before baking a large cake. • These little test cakes were called "koekje", meaning "little cake" in Dutch • In 1853 the first fry was made. • The first potato chip was made in 1853 also.

6. Step by Step • Cut a large square from the brown paper bag. Make sure the square contains NO printing. • Stretch out a large piece of aluminum foil to place your food samples on. • Place a ½ teaspoon of butter, yogurt, French onion dip, and peanut butter on the foil. • Cut the avocado in half and scoop out ½ teaspoon to add to your samples. Use the remaining avocado for dip. • Slice a small piece of bacon and place it on the foil, followed with a few potato chips and a piece of chocolate chip cookie. • Use the marking pen to make a list of your food samples on the square of brown paper. Leave lots of room between each item of your list. • For all the food samples, except the bacon, potato chips, and cookie, take a cotton swab and rub it in the sample. • Rub the cotton swab on the brown paper (next to the word on the list) to make a smear. • Pick up the bacon with the tweezers and rub it on the paper. • Pick up the chips and cookie and rub them on the paper. • Leave the paper for two days to observe.

7. Controls/Variables • I don’t have a control. • All the different types of foods are my variables.

8. Observations • At the time that I put the food on the cardboard some had speckled dots all around it. • After one day some of the rings started getting really big and some stayed the same size.

9. Data

10. Analysis of Data • Peanut Butter- 4 ¼ inch ring of fat • Butter- 3 1/3 inch ring of fat • Potato Chip- 2 ¼ inch ring of fat • Raw Bacon- 1 ½ inch ring of fat • Avocado- 1 ¼ inch ring of fat • Yogurt- 1 ¼ inch ring of fat • French Onion Dip- 1 ¼ inch ring of fat • Chocolate Chip Cookie- ½ inch ring of fat

11. Conclusion • My hypothesis was correct on some and some were not correct. • I would change the different food samples. • What if I put the food samples on cold, hot, or bumpy surfaces, what would happen?
