Which of the leading brand paper towels is more absorbent; Brawny, Bounty, Sparkle, or Scott?
Relevance of Testable Question
The relevance of this test question is to determine which brand of leading paper towels is the best most absorbent. Consumers want to use the product that is most effective at meeting their needs. A more expensive product may actually be more cost effective if you can use less of it than a brand that costs less.
Many experiments have been conducted to test the strength and absorbency of paper towels. While the steps of the experiment vary from test to test, all of experiments are testing the same two factors; how ...view middle of the document...
The second part of the experiment is conducted by stretching sheets of each paper towel through an embroidery hoop, placing 25 pennies in the center of the paper towel, and adding water to the towel drop by drop until the pennies fall through. The strongest paper towel in this test was Brawny Brand.
The final experiment that I reviewed also tested for absorbency. The theory behind this experiment was the faster that water moves through the towel, the more absorbent it is. The experimenter cut strips from each paper towel, one inch wide and six inches long. A mark is drawn on each paper towel one inch from the end using a waterproof marker. The strip is then held in a glass of water with the bottom inch submerged, timing how long it takes for the water to travel the length of the strip. The process is then repeated for each brand that is being tested. The most absorbent brand in this test was Brawny.
A. Steps in Experimental Procedure
The absorbency of the towels will be tested by the speed the water moves through the paper towels, the faster the water moves, the more absorbent the towel is. I will be using the following brands of paper towels in my experiment: Brawny, Bounty, Sparkle and Scott. Other supplies necessary to complete the experiment are: a waterproof marker, and a sixteen-ounce glass of water, and a timer that registers tenths of a second.
1. Prepare three samples of paper towel from each brand by cutting strips of each that is 2 inches wide and six inches long.
2. Using a water-proof marker, draw a line across each paper towel one inch from the bottom.
3. Fill a sixteen ounce glass with water and prepare timer.
4. Take the first strip of paper towel and submerge it up to the line in the glass of water while holding it vertical to the glass while starting the timer.
5. Allow the timer to run until the water is absorbed through the paper towel and reaches the end of the towel not submerged.
6. Stop the timer and record the time in tenths of seconds.
7. Repeat steps 4 through 6 for all three strips of each brand.
B. Reasoning for Choosing my Experimental Design Plan
The reason I chose this design for my experiment is because it seemed to be more accurate than other testing methods I found during my literature review and could be performed with items I already had in my home. The experiment where the tester rang out the paper towels and measure the water that they had absorbed is less accurate because there is no guarantee of exerting the same amount of force each time you ring out a towel. There is no way to completely drain the towel of all of the liquid it absorbed. Stretching the paper towel samples across the embroidery frame is sound way to perform the experiment but it would have required the purchase of additional materials.
