Question: Which brand of popcorn leaves behind the most unpopped kernels after being popped?

Hypothesis: If the brand of popcorn is related to the amount of unpopped kernels that are left, and three different brands of popcorn are popped for the same amount of time, then the more expensive brand of popcorn will have the least amount of unpopped kernels left behind.

Prediction: We predict that the more expensive brand of popcorn will produce the least amount of unpopped kernels.

Independent Variable: brand
Dependent Variable: # of unpopped kernels
Control Variables: hot plate temperature, # of kernels, cooking time, fan, sides closed on table, amount of olive oil

SUMMARY OF EXPERIMENTAL DESIGN (materials and methods)
Does the brand of popcorn affect the amount of unpopped kernels?
Rebecca Pappas, Kourt Sherrod, Olivia Cherry
New Providence Middle School, New Providence, NJ


As we performed the nine tests (three tests for each brand of popcorn), we recorded how many kernels were unpopped for each trial.
The first time we tested America's Choice buttered popcorn, there was 11 unpopped kernels. The second time, there were 6 unpopped kernels. The last trial, all of the kernels popped.
When we tested Orville Redenbacher's buttered popcorn for the first time, there were 6 unpopped kernels. The second time, there were 4 and the last time, there were 3.
The last brand we tested was Pop-Secret. The first time we tested this brand, there were 15 unpopped kernels. The second time, there were 18. The third time, there was 8.
After testing, we decided that we needed a number that we could compare all of the brands with. So, we calculated the average amount of unpopped kernels for each brand.
One of the most popular snacks in the United States is popcorn because of it's texture and flavor. It is assumed that the movie-theater snack is native to Central American Indians who grew corn on their land.
With so many different brands of popcorn, there are many sizes, textures, and flavors to chose from. When choosing you snack, it is important to know to know what you are getting. After years of eating popcorn, we noticed that different brands of popcorn leave behind different amounts of unpopped kernels.
To test this idea, we decided to do some research. We investigated three different popcorn brands and found out their price, where they are sold, and the nickname for each brand. This is what we found:

Pop Secret: cost- $6.32 per pound; "high end"; sold at almost all grocery stores

Orville Redenbacher's: cost- $6.05; "brand name"; sold at almost all grocery stores

America's Choice: cost- $5.16 per pound; "grocery store brand"; sold at a select amount of grocery stores.
(average; 5 2/3)
(average; 4 1/3)
(average; 13 2/3)

What brand of popcorn do you think is more efficient? Our prediction was that the more expensive brand of popcorn (Pop-Secret) would produce the most popped kernels. However, once we started to test each of the brands, we discovered that this wasn't the case and that the "medium priced" popcorn brand was the most efficient.
Once we collected our data, we calculated the average of unpopped kernels for each brand.The average for the least expensive brand (America's Choice) was 5 2/3. The middle priced brand's average (Orville Redenbacher's) was 4 1/3. The most expensive brand (Pop-Secret) and the brand that we thought would be the most efficient average was 13 2/3.
This data disproves our prediction because the most expensive brand of popcorn was the least efficient and had the highest average of unpopped kernels (13 2/3).
Knowledge is power; when people know which brand is the most efficient, they can buy their popcorn accordingly. They will benefit from this by getting more popcorn for their money.
Although we performed this experiment, that doesn't mean that future research can't be done. One thing that could be done in the future to further our knowledge about different popcorn brands is testing more of them. We only tested three for the sake of time, however, it would be interesting and helpful to see the results of more brands.
One thing that we could have done to make our experiment more accurate is perform more tests for each brand of popcorn. When you have more data to base your conclusion off of, then the conclusion will be more accurate.
To get a number that we could compare each of the brand with, we created averages. We evaluated the brands by seeing which brand had the lowest and highest average of unpopped kernels.
Our experiment didn't show any significant pattern, although, two out of the three popcorn brands decreased in the amount of unpopped kernels as the trials went on. In the first trial, America's Choice had 11 unpopped kernels in the first trial. In the last trial, there were no unpopped kernels. The same pattern occurred with the brand Orville Redenbacher's.
The graphs for these two brands verify this pattern; they both show that as the trial number increases, the number of unpopped kernels started to decrease. With the brand Pop-Secret, the graph and results chart shows that there is no correlation between the trial number and the amount of unpopped kernels.
One thing that stood out to us in the individual graphs was that in trial 3 for America's Choice, there were no unpopped kernels. This seemed really since most brands had at least 3 or more unpopped kernels, therefore, the
number zero is an outlier. We think that this
might have happened because there was too
much oil in the pot from previous tests.
The smallest increment for our test is
one kernel. This means that the uncertainty
in our data is +/- 1 for each number.
