I believe that Walmart brand paper towels are just as absorbent as Bounty brand paper towels. All paper towels are made from paper pulp that is woven to create a large sheet. Because all paper towels are made from the same material I believe that the Walmart brand will absorb just as much liquid as the other brands. I will prove my hypothesis through a scientific experiment comparing three brands of paper towels. I chose three brands with three very different price points. Am I paying more money per roll for a higher quality towel or are all paper towels made the same, therefore will absorb equal amounts of liquid. I will put each paper towel brand through an absorbency test 4 times to get an average amount of liquid absorbed. I am interested in this experiment because we are a family on a budget and if the Walmart brand paper towel is just as absorbent as the more expensive Bounty brand that will save us money on our grocery budget. I researched 2 other paper towel absorbency experiments. An experiment by Samantha P.(www.selah.k12.wa.us, 2001) hypothesized that Bounty would be the most absorbent brand, while ZHukant(“essay-collection.blogspot.com”, 2006) hypothesized that Job Squad would be the most absorbent brand in that experiment. Both experiments had a well-defined experimental plan. I was able to replicate both after conducting my own experiments. Samanthat P. and I did multiple trials with each brand of towel. ZHukant only conducted one trial per brand. ZHukant and I both cut our paper towels down to the same size so that the experiment was as controlled as possible. Samantha P’s hypothesis was found false in all four trials. She found that Sparkle brand was the most absorbent. ZHukant’s hypothesis was proven true; Job Squad was the most absorbent brand. My experimental procedure will be conducted in the following steps. 1. Gather all items needed for experiment. At least 3 different brands of paper towels, 2 liquid measuring cups, water, a stopwatch,...
