As students create their timelines, they might consider posting only information they can verify by more than one source. Then they tally the number of kernels of unpopped kernels in their bowls. We decided to compare the following methods: microwave, stove top and hot air popper. How would I do her graph? If I redo my experiment I would change the time I pop each bag of popcorn for from 3min to 2min. Also, in order to get an accurate count of kernels, I have been opening the bags and he has been counting the kernels to start with, then I tape the bags back up and microwave. When the kernels are heated, the water inside heats up to the point where it exerts enough pressure to burst the kernel open.

I won't try to duplicate it, but you can find the link here: Let me know if you have any additional questions from that discussion and good luck on your project! The first brand we popped burnt if left in longer than 1 min 45 sec. I would soak in vinegar think salt and vinegar If you are trying to impart a sweet tasteâ€¦. Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances. Tell students they have 2-3 minutes to shuck the corn and estimate the number of kernels of corn on the ear. Use a needle to make several tiny punctures in the outer covering of a handful of popcorn kernels. They might work images of corn plants or popcorn into their timelines. A popped piece of corn is about 20 to 50 times larger than the original kernel.

Yes â€” ultimately you will make a bar graph with the type of oil on the x-axis and the number or percentage of kernels on the y-axis; The control depends on the question. If these types of corn are dried so they have the right moisture content, a small number of kernels will pop. If the kernel is heated to a high enough temperature, this water will transform into steam. Please note that because it deals with hot oil, students attempting this experiment will need adult supervision and help! Which brand had the best popping results the most seeds popped; the fewest kernels unpopped? A chosen number of kernels are placed in a pan over a low flame, medium flame and a high flame, with the student recording how long it took the popcorn kernels to pop. You can also evaluate popcorn quality by measuring kernel expansion, which means how big the popped popcorn flakes get.

My hypothesis is the microwave will leave least amount of uncooked kernels. I am confused on what our control will be or if we need one for this experiment? Remember you must, must, must replicate, replicate, replicate! These lesson plans will engage students as they create popcorn timelines, maps, and graphs; do popcorn science and math; explore popcorn history and nutrition; and, munch leftover popcorn snacks too! If you are doing this experiment with younger students, you might want to puncture the kernels yourself. Temperature One more category of popcorn-related science fair experiments looks at the role of temperature in popping popcorn. To ensure accuracy, students might record a mark for every ten pieces of popcorn they eat. Utlimately you want an average for the results not the method steps , but make sure you show all three trials and the average â€” otherwise you run the risk of the judge thinking you only did one trial. The kernels probably changed color and turned from yellow to brown during heating. Instruct the students to count the kernels by sorting their share into groups of ten.

Once the pressure gets high enough and the temperature reaches about 180 degrees Celsius 355 degrees Fahrenheit , the kernel hull bursts and the popcorn is turned inside out. Does each brand of popcorn have to be the same amount in oz. Place a popcorn popper in the center and let the popcorn pop -- uncovered! It's why we're in business. Each bar will represent the average of the three bags for that brand and butter status. The most common types of popcorn have white or yellow pearl-type kernels, although white, yellow, mauve, red, purple, and variegated colors are available in both pearl and rice shapes. The graph will provide a visual reference point to help students see which states grow the most corn.

Some of our parents and grandparents grew popcorn, packaged it, and sold it door-to-door or store-to-store. My question do we have to much going on. Christopher We are doing the experiment on which yields more popped kernels: plain or buttered popcorn. For further information, consult your state's handbook of Science Safety. You can measure the effectiveness of popping in several ways: number of kernels popped, number of kernels that did not pop, percentage of popped popped divided by total number of kernels , percentage unpopped, etc. You will not be able to conclude it is better because of any one of those differences. Another way to study temperature is to pop kernels on the stove at different heat levels.

Replication is an important part of any experiment and one that is often overlooked in science fair projects. The pressure builds up inside the kernel until it bursts. We are confused about different variables constant, control, Independent, and Dependent? To vary the temperature of popcorn, some bags of microwave popcorn should be frozen, others refrigerated, others left at room temperature and the last heated in an oven at 50 degrees Celsius for 20 minutes. Place one kernel of popcorn in the bottom of the tube. This is my second science fair project and my mother did most of the work on my first one.

Students will not comprehend the large numbers that appear on the chart, but you can help them understand by using 17 kernels of corn to represent 1. The commonly cultivated strain is Zea mays everta, which is a type of flint corn. For each bag, count the number of popped and the number of un-popped so that you have a total number of kernels popped + un-popped. . Riley I am comparing the three cooking methods to determine which leaves least amount of unpopped kernels. Temperature One more category of popcorn-related science fair experiments looks at the role of temperature in popping popcorn. How do we need to control the oil for stove top and popper? We decided to compare which method of making popcorn is the most efficient.

This is a tricky one because of the way you have asked the question. There where no problem during the experiment. Should we compare one brand to the same brand several times or should we compare different plain brands to different buttered brands? My science teacher suggested temperature as a constant but How would I find the temperature of stovetop and air popped. Experiment 1: The Control Experiment. Some wild or heritage strains of corn will also pop. My question is which method of making popcorn will leave the least amount of kernels? Talking parents down off a ledge and responding to parent whining and excuses. Or did the holes let more steam escape and prevent pressure from building up inside the kernels? Tilt the lid on the pot so steam can escape but be careful not to let hot oil splash out of the pot.
