Paper Towel Experiement Essay Example for Free

Paper Towel Experiement EssayMy wife and I go through an bulky tally of report card products. We discuss often which brand works best for the bell. Typically, we buy the brand Bounty for our root towel selection. There is no event reason why we buy this brand but it seems to be the one we get home with. After reviewing some some other literature in regards to the base towel experiment, I found some different results. According to Consumer Reports ( two hundred9), Brawny was the close absorbent of all of the 21 brands that they tested. They found that Brawny held 2 ounces a good deal(prenominal) per solid foot on average than the other brands tested. However another consumer, Chelle from Yahoos Contributor Network, found that Bounty was the virtually absorbent motif towel. She tested Scott, Brawny, and Bounty. (2010)Twelve year old Samantha too performed an experiment on paper towels testing four brands Bounty, Sparkle, Scott, and Western Family. Her hypothesis w as that Bounty would be the or so absorbent but after her experiment reported that Sparkle absorbing 50 ml of water on average. (2001) Mrs. McKees class from Arizona also did a paper towel experiment. They tested their schools paper towel, Brawny, Bounty, Viva, Scott, and a generic brand. The results from their experiment showed that on average Viva was found to be the most absorbent. (2012) After looking at other research and preforming my literature review, I decided to test four paper towels Bounty, Brawny, Viva, and Kroger Brand. I decided that I would use 200 ml of water and place each brand of the folded paper towel in the water five different sentences. I cast to squeeze the water into a beaker and measure how much water was absorbed. I would then take the average to find out which brand of paper towels was more absorbent.Problem What paper towel is the most absorbent and leads to the most cost effective? Materials1 Glass container denominate with ml to 750 ml1 undersize beaker labeled with ml to 150 ml1 stop watch1 baby bottle (I only had one glass container with ml labeled) labeled with ml to 260 ml Paper Towels Bounty, Brawny, Viva, and Kroger Generic Brand (4 brands X 5 sheets) Water1 FunnelPen and PaperPrices on the paper towels were how much I paid per roll, but with further investigation I found that the price per square foot was different. Independent Variables Brand of Paper Towel, price per square foot Dependent Variable Amount of Water Absorbed, Vivi sheets were much undersizeder than the other sheets and two sheets were used and cut to the same size as the other sheets price is gloss over based on per square foot for each paper towel Constants Amount of water used in each trial, paper towel size, time exposed to the water, type of fluid (water used) I get out make sure to use the timer to submerge the paper towels for the same amount of time. I will use the same measuring instruments for each experiment. Hypothesis Because Bountys r oll of paper towel cost the most, Bounty will absorb the most milliliters of water per square foot. I came up with this hypothesis because I wanted to show my wife how we could save money by go on to buy the name brand paper towel.Data Collection ProcessEach paper towel was folded four times to create a small square. Each paper towel was emerged into 200 ml of water and left for 20 seconds. Each paper towel was removed from the water allowing drip time of 5 seconds and then the remainder of the water was squeezed to a beaker. The left over water was poured into a baby bottle for measurement in milliliters. At foremost I was going to use the amount of water that I could squeeze out of the paper towel, but then I realized that some was still left over in the paper towel. To reduce the threats to internal validity, I then decided to subtract the amount of water left over from 200 ml to get an accurate reading of how much water was actually absorbed.ConclusionResults from my experimen t indicate that per square foot, Viva paper towels are the most absorbent. In addition, since Vivas price per square foot was 4 cents, it would also be the most cost effective. Viva paper towels absorbed on average 8 more milliliters than Bounty and Brawny and 13.4 milliliters more than the generic Kroger brand. At first glance, Bounty looked like the most expensive paper towel with Viva 2nd. However, when you look at price per square foot, the price of Viva and Bounty are the same. Brawny is actually the most expensive per square foot. With this universe said, my experiment refuted my hypothesis that Bounty was the most absorbent because it cost the most.Bounty was not the most cost effective because it did not absorb the most and the price per square foot was the same as Viva. Price per square foot indicated that Brawny was in fact the most expensive and it still was not the most absorbent. It is imperative when doing an experiment that the experiment is done with several trials and that the procedure are completed in the same manner. This adds to the validity and reliability of the experiment. To replicate this experiment, you must exhaust the above materials. Choose at to the lowest degree 4 paper towel brands.Fold each paper towel (five trials per towel) four times.Submerge each paper towel individually into 200 milliliters of water for 20 seconds. Remove the paper towel, allowing it to drip for 5 seconds.Measure how much water is remaining and subtract that payoff from 200 to see how much water the paper towel absorbed. Record this and continue the step for each of the remaining paper towels. It is recommended to do at least 5 trials per brand of paper towel. When others perform the same experiment, it validates the results from my experiment.ReferencesChelle. (2010)Which Brand of Paper Towels is the Most Absorbent?
