Do different brands of popcorn affect how many kernels pop? Introduction
The grocery store shelves are filled with many varieties, sizes, and brands of the same item. There are numerous kinds of popcorn, large and small, produced by different manufacturers. Some people choose products based on need, some base their decisions on price and some base their decision on quality or brand loyalty. With all of these options it can be difficult to choose. You may want to save money but at what cost? In this experiment we will determine if generics are equivalent alternatives or if we really get what we pay for. (Bautista, 2006) Project Design Plan
Testable Question: Does name brand popcorn will have a better ability to pop than generic popcorn? Independent variable- Name brand and generic popcorn
Dependant variable- Time and temperature
By changing the time and temperature we change the ability of the popcorn to pop. If the temperature is too low or it if the time is too short then the popcorn will not pop at all.
Overall Project Plan: Two types of popcorn (name brand and generic) will be popped for the same amount of time and temperature to see which one pops better in 30 seconds. Then, the unpopped kernels will be counted and recorded. The one that pops better will have fewer totally unpopped popcorn kernels left.
Revelence: With all of the options of popcorn it can be difficult to choose which one to buy. Does a person sacrifice savings when buying generic for quality? In this experiment we will determine if generics are equivalent alternatives or if we really get what we pay for. Many different brands and types of popcorn are available on your grocer’s shelves, such as Orville Redenbacher, Pop Secret, Cousin Willie’s, and a generic grocer brand, all offered in light, regular, and butter. All of these brands claim different slogans and catch phrases in order to sway the consumer into purchasing their product. Our goal is to cut through possible false advertising, and educate students on “ do generics or name brand popcorn have the most kernel efficiency”.
Literature Review - Review of similar projects
Project A: Used 3 bags of popcorn for 4 separate brands and microwaved them for 2min 30sec. Open 1 bag at a time, count the number of unpopped kernels (any unbroken shells), record data on data sheet, calculate the percentage by dividing the number of the actual popped kernels by the total number of kernels left in the bag. It was determined that Orville Redenbacher had the fewest unpopped popcorn kernels left in the bag. Data was recorded in paragraph format. This is related to the current investigation for the fact that they are both collecting data on unpopped popcorn and relate brands to different popability. (Saum, 2001) Project B: Count one hundred kernels of corn from three brands of popcorn, Orville Redenbacher, Kroger, and Act II. Pop the kernels from each brand one at a time. At the completion of the popping for each brand, count the number of unpopped kernels. Repeat this process for each brand a total of three times. Average the results of the three trials for the individual brands. Compare the averaged results for each brand and the price per kernel of each brand. The brand that cost the most per kernel does not pop the most popcorn. This shows that the price of the popcorn does not reflect the quality of the kernel. Results were recorded in paragraph format and a bar graph was created using those results. This is related to the current investigation for the fact that they are both collecting data on unpopped popcorn and relate brands to different popability. (Sayles) Experimental design steps and Reasoning:
Step 1- Gather Materials:
2 different brands popcorn- 1 generic brand and 1 name brand Peanut oil
Large pot with top
Step 2- perform experiment; Begin process with generic popcorn. Follow the same process for a total of 3 times for the generic. Then,...
