Transcript of Ava's Science Fair Project!!

Can different preparations of popcorn improve the "popability"? By:Ava Floyd Hypothesis

If the popcorn is oily, then more kernels should pop because usually you use oil to make something cook better. Variables

The independent variable in my project is the vegetable oil. The dependent variable is the popcorn kernels. The control variables in my experiment are the bowl, the microwave, the paper bags and the popcorn kernels. Research

I learned that my topic was going to include popcorn. I also learned that my topic originally needed to have a hot-air popcorn popper. In addition, I learned that using water may help the popcorn pop.

I learned that some people think that popcorn is healthy. I also learned that because of an elementary school project, popcorn became the official state snack food of Illinois. In addition, I learned that air-popped popcorn is naturally high in fiber.

I learned that popcorn’s scientific name is zea mays everta. I also learned that popcorn is the only type of corn that will pop. In addition, I learned that it’s believed that the Wampanoag tribe brought popcorn to the first Thanksgiving. Materials

•10 bags of popcorn
•Enough Vegetable oil to cover all the kernels
•5 Bowls
•1 Microwave
•5 Paper bags Procedures

1.First get out all materials and place on a clean surface near microwave.
2.Next follow the steps on the popcorn bag.
3. When the popcorn is done popping and is cooled count how many kernels did not pop.
4.Repeat step 2 and 3 for another 4 bags of popcorn.
5.When you have finished step 4 open another bag of popcorn (not yet popped) and place the kernels in one of the bowls and coat the kernels with vegetable oil and then let it sit over night.
6.In the morning place the kernels in a paper bag and fold the paper bag closed three times and place in microwave for two minutes or until the popping in between kernels becomes five seconds then take out the popcorn and let it cool down then count how many kernels did not pop.
7.Repeat steps 5 and 6 for another four bags of popcorn.
8.Then see which method popped more kernels.
Safety

Since I am using a microwave I will have a parent take the popcorn out of the microwave for me. I will wear an apron to protect my skin and clothing in case the vegetable oil spills. In case for some reason the microwave catches on fire I will tell an adult and will not try to put it out myself. Observations

Trials without oil
1A- With fifty seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of eight kernels had popped.
1B- With fifty seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of six kernels had popped.
1C- With a minute and one second left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of eleven kernels had popped.
1D- With a minute and twenty seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 7 kernels had popped.
1E- With 32 seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 7 kernels had popped.

Trials with oil
2A- With a minute and five seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 10 had popped kernels had popped.
2B- With forty-nine seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 9 kernels had popped.
2C- With forty-seven seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 6 kernels had popped.
2D- With fifty-seven seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 11 kernels had popped.
2E-With forty-five seconds left in the microwave I heard the first pop from the popcorn. The popcorn needed an additional 30 seconds in the microwave because not a lot of popping happened during the first time it was in the microwave. When I took out the popcorn and looked in the bag I saw that only a total of 15 kernels had popped.



Conclusion

In my hypothesis I said that the oily popcorn would have more kernels popped and that the dry popcorn would have more unpopped kernels because you use cooking oil to make something cook better. After testing it both ways five times, I have concluded that my hypothesis was correct that the popcorn with oil cooked better. Here are the trials for the kernels without oil: In the first trial eight out of the hundred kernels popped. In the second trial six out of the hundred popped. In the third trial (this trial was the best for the kernels without oil) eleven out of the hundred popped. In the fourth trial the results were the same as the second trial. In the fifth trial seven out of the hundred popped. Here are the trials for the kernels with oil: In the first trial ten out of the hundred popped. In the second trial nine out of the hundred popped. In the third trial six out of the hundred popped. In the fourth trial eleven out of the hundred popped. In the fifth trial fifteen out of the hundred popped. Therefore using oil the average number of kernels that popped was 10.2 kernels versus 7.6 kernels without oil.

In my research, I learned that some people think popcorn is healthy. I learned that because of an elementary school project, popcorn became the official state snack food of Illinois. I also learned that air-popped popcorn is naturally high in fiber. I learned that popcorn’s scientific name is zea mays everta. I learned that popcorn is the only type of corn that will pop. I also learned that it is believed that the Wampanoag tribe brought popcorn to the first Thanksgiving. One thing I was surprised about in my experiment is that more kernels didn’t pop in all my trials.

I would like do this experiment again letting the popcorn microwave for a longer amount of time. I learned from doing my experiment that the longer the popcorn cooked the more popcorn would pop. Also, I would like to try the experiment again using not just oil but also water and some other drinks maybe milk and Gatorade. I think it would be interesting to test it using a stove top and not a microwave. I wonder if that would affect the amount that popped?
