**Oreo Challenge**

### By: Yvonne Yang, Faith Fong, and Danielle Liu

## Introduction

We decided to investigate whether or not Double Stuf Oreo cookies actually have double the amount of cream than regular Oreo sandwich cookies. In order to do this, we decided to conduct an experiment. In our tests, we compared the weights of regular Oreo cookies and the weights of Double Stuf Oreo cookies. Then, we calculated the average weight of the regular Oreo cookie cream to the average weight of the Double Stuf Oreo cookie cream. Our results showed us that the Double Stuf Oreo cookies genuinely have double the amount of cream in comparison to regular Oreo cookies.

### Identification of Variables

Independent Variable- Type of Oreo weighed

Dependent Variable- Weight of the Oreo

Question:

Do Double Stuf Oreos have double the amount of cream in comparison to regular Oreo cookies?

### Background Information:

Oreo cookies have been a favorite cookie brand in the United States since 1912, when Nabisco first invented the cookie made of two biscuits filled with cream. Double Stuf Oreo cookies were introduced in 1975. According to their name and advertisements, these Double Stuf Oreo cookies have double the amount of cream in comparison to regular Oreo cookies. However, how can we know that these advertisements are true?

People do not often to stop and think about false food advertisement. However, when they do, it is obvious that there are many food products that are falsely advertised. Many food products look entirely different than they appear on television. For other food products, the "facts" listed on the fronts of boxes are not true. With some experimentation, we were able to verify Nabisco's claims that Double Stuf Oreo cookies are truly double stuffed.

### Hypothesis:

If the cream in Double Stuf Oreo cookies and regular Oreo cookies are weighed, we will find that the Double Stuf Oreo cookies weigh twice as much as the regular Oreo cookies, meaning that Double Stuf Oreo cookies are not falsely advertised.

## Methodology

### Materials:

- One bag of regular Oreo cookies
- One bag of Double Stuf Oreo cookies
- One scale
- One knife
- Napkins
- Notebook and pencil

### Procedure:

1. First, gather all of your materials.

2. Tear a smaller corner of the napkin. This torn napkin piece should be approximately 2 1/2 inches by 2 1/2 inches.

3. Take the smaller napkin piece and place it on the scale. Calibrate the scale to 0 grams.

4. As neatly as possibly, separate the two chocolate biscuits so that one biscuit has cream on it and the other biscuit does not.

5. Take the biscuit with the cream and use the knife to separate all the cream from the cookie.

6. Wipe all cream from the knife onto the napkin corner.

7. Place the napkin with the cream onto the scale. Find and record the weight of the cream. (Note: The weight of the napkin will not be included when the cream and the napkin are weighed because the scale has already been calibrated to 0 grams. Refer to step 3.)

8. Remove the napkin with the Oreo cream from the scale. If needed, wipe the scale clean. This will ensure that your next measurement will be accurate.

9. Reset the calibration of the scale.

10. Repeat steps 2-9 four more times to get a total of five trials. Find the weight average of the five trials.

11. Repeat steps 2-9 five times. However, for these five trials, use the cream from the Double Stuf Oreo cookies instead of the cream from the regular Oreo cookies. Find the weight average of the five trials.

12. Compare the average weight for the cream of the regular Oreo cookies to the average weight for the cream of the Double Stuf Oreo cookies.

## Results

Through our experiment, we found out the weights of a number of regular Oreo cookies and Double Stuf Oreo cookies. The first regular cookie we weighed was about 3.2 grams, the second was 3.1 grams, and the third, fourth and fifth cookies were 3 grams. For the Double Stuf Oreos, the first and second Double Stuf cookies we weighed were 6 grams, both fourth and fifth were 6.1 grams, and the fifth was 6.3 grams. The average weight of the regular Oreo cookies was about 3.06 grams. The average weight of the Double Oreo cookie was about 6.1grams.

As we analyzed our data, we saw that the average weight of the Double Stuf Oreo cookies was approximately double the average weight of the regular Oreos.

Below is a graph that shows our data.

## Discussion

In our hypothesis, we stated that if Double Stuf Oreos have double the stuffing, then they are not falsely advertised. After performing tests, our final conclusion is that Double Stuf Oreos do not make inaccurate claims about their stuffing. Taking precise measurements and analyzing our results, we can confidently state that our hypothesis was correct. Double Stuf Oreos are not falsely advertised. In fact, they are, indeed, double stuffed. Our results from the first set of tests on the regular Oreos determined that the original sandwich cookies had 3 grams of cream. Subsequent analysis on the Double Stuf Oreos yielded satisfying outcomes: they each contained 6 grams of cream. We performed 5 trials on the Double Stuf Oreos and the average weight of cream proved our hypothesis to be correct. The Double Stuf Oreos truly have double the stuffing, or 6 grams of cream per cookie. However, one step we neglected during this experiment was calibrating the scale before beginning our trials. So, to improve our tests' accuracy next time, we would need to make sure that our scale is calibrated to zero every time before we weigh each individual Oreo's stuffing. Still, our slight error did not make much of a difference in the results of our experiment because the scale usually did not register the weight of the napkin.

Our results can be somewhat surprising to the general public because sometimes, in order for companies to make money, they tweak the facts in advertisements to appeal to society as well as to keep an eye on finances. In our research before the actual tests, we were given evidence of false advertisements, so that may have been a common strategy in marketing. The false advertisements of other companies aroused our suspicion about the real quality of these sandwich cookies. Therefore, we used science to ultimately answer our question.
