Which brand that popcorn leaves behind the most unpopped kernels after gift popped?

1) Unwrap all nine bags of Popcorn2) chef each bag that popcorn because that 2 minutes3) separate each brand the popcorn4) brand 3 plastic or file cups v 1,2,3.5) beginning with one brand, pour one bag that popcorn into a bowl6)From the bowl, pick out every one of the whole pieces that popcorn and also put them into a freezer bag or selected container7) take it popcorn kernels out and also count them8) location popcorn kernels in the correct numbered cup9)Repeat counting and also sorting kernels because that each of that brand"s various other 2 bags10) document the data in your chart11) Repeat measures 5-10 for the various other two brands12) To compare all the brands, calculation the average of every brand of popcorn by adding the 3 numbers of the unpopped kernels, one brand in ~ a time, and divide by 3.13) after counting the unpopped kernels for all 9 bags, look at the data collected to watch what brand had the most unpopped kernels.

What occurred & Why?

The Question

Variables

Independent: Brand that popcornDependent: variety of unpopped kernelsControl: Time every bag is popped (2 min.), every bag is butter flavor, 3 bags of each brandConstants: Microwave, temperaturePurpose of the experiment: To discover the brand of popcorn that uses the best amount the popcorn with the smallest variety of unpopped kernels in a bag that butter popcorn because that consumers.

Background Infomation

-3 bags that 3 various popcorn brands(Pop-Secret, Orville Redenbacher"s, pop Weaver butter popcorn)-Microwave-Napkins-Red Solo cups-Sharpie-Bowl-Calculator (if needed)-Computer or document (pencil if needed) to record data

My theory is the the brand Pop-Secret will have actually the least amount that unpopped kernels, Orville Redenbacher"s will have the second least, and also Pop Weaver will have actually the most unpopped kernels after every bag is cooked for two minutes. This is based on the expense of each brand. (\$2.28, \$2.18, .88)................................................................................................................................................................................................................................................................................................

After popping 3 bags of the exact same popcorn brand because that 2 minutes each, ns have found that pop Weaver popcorn has the in its entirety least quantity of unpopped popcorn kernels (58,26,26). Pop weaver was the cheapest the end of the 3 brands at 88 cents (OR: \$2.18, P-S: \$2.88). I think Pop Weaver had the least amount that unpopped kernels since two minutes was all that was required to popular music the entire bag. This brand was practically burnt for all three bags ~ 2 minutes in the microwave. After pop Weaver, Orville Redenbacher"s (118, 71, 76) had the second least lot of unpopped kernels and Pop-Secret had actually the most unpopped kernels (188,165,102). The results are the complete opposite of mine hypothesis. I thought that the many expensive brand would have actually the the very least amount that unpopped kernels, but in fact the cheapest brand of popcorn had actually the smallest amount that unpopped kernels. Conclusion:What brand of popcorn is much more efficient? my prediction was that the an ext expensive brand the popcorn (Pop-Secret) would produce the the very least amount of unpopped kernels. However, after testing the brands, the cheapest brand of popcorn to be the most efficient. The data disproves my prediction because the most expensive brand the popcorn to be the least efficient and had the greatest average the unpopped kernels (151.6). This uses to the real world due to the truth that consumers deserve to use this data to buy a brand of popcorn that gives them the most product because that the cost. In the future, consumers can be further helped by researching more brands that popcorn throughout various price ranges. More research could also be done to check out if the data would certainly be similar if I offered kettle corn and popped the kernels top top the stove. In this experiment, ns was minimal due come time, however researching much more brands would expand the data to reach an ext consumers.

"Each kernel the popcorn has a tiny drop that water stored within a one of soft starch. Popcorn needs in between 13.5-14% humidity to pop. The soft strength is surrounding by the kernel"s tough outer surface.As the kernel heats up, the water starts to expand. Approximately 212 degrees the water turns into vapor and transforms the starch within each kernel into a superhot gelatinous goop. The kernel continues to warmth to around 347 degrees. The push inside the grain will certainly reach 135 pounds every square inch before finally bursting the hull open.As the explodes, vapor inside the kernel is released. The soft starch within the popcorn i do not care inflated and spills out, cooling immediately and also forming right into the odd shape we know and also love. A kernel will swell 40-50 times its original size (The Popcorn Board, 2013)."The determinants that affect a kernel"s "popability" is the moisture inside the kernel (water content), the condition of the hull (the exterior of the kernel), and also the amount of a kernel"s hull that crystallizes (Skloot, 2005).Above is the scientific explanation of just how kernels pop and also why there room kernels that execute not pop. This details is essential in determing why a details brand the popcorn may have actually many much more unpopped kernels than another brand.
