Initial Observation: I noticed that when my parents buy paper towels, some brands rip faster than other brands. Information Gathering: I went to the Grocery Store and picked out three different brands of paper towels with different prices. Purpose: The purpose of this experiment is to find out if the more expensive brands of paper towels really are stronger than the cheaper brands like they say on the bag. Hypothesis: I believe that the more expensive brand will be stronger because it is probably made up of a stronger material. 1.) I went out to the Grocery Store and bought three different brands of paper towel at different prices. 2.) I taped on side of the paper towel to a table and held the other side with one hand.
3.) I sprayed 15 sprays of water with a spray from a glass cleaner bottle on each paper towel. 4.) I stacked apples on the wet paper towel until the apples fell through the towel. 5.) I counted the number of apples it took to tear the paper towel and recorded the number. 6.) I repeated this procedure three times for each brand of paper towels. – 3 different brands of paper towels (Topcrest, Bounty, and Kleenex Viva) For the Kleenex Viva (the most expensive brand) it took 11 apples to tear the paper towel the first time. It took 10 apples to tear in the second trial ,and it took 11 apples to tear it in the third trial.
For the Bounty (the second most expensive brand) it took 9 apples to tear it the first time, second, and third time For the Topcrest brand (the least expensive brand) it took 3 apples tear it the first time. It took 3 apples to tear it the second time, and it took two apples to tear it the third time. I noticed that all the apples were not the exact same weight or size so my results may vary a bit, but I used the same apples for each trial and each brand of paper towel. It was also hard for me to hold the paper towel while putting the apples on top of it. I had to ask for some assistance from my mom because the apples kept falling off the paper towel. I doubt that this made a big difference in my data and results.
The Review on Paper Towel Experiement
My wife and I go through an enormous amount of paper products. We discuss often which brand works best for the price. Typically, we buy the brand Bounty for our paper towel selection. There is no particular reason why we buy this brand but it seems to be the one we get home with. After reviewing some other literature in regards to the paper towel experiment, I found some different results. ...
Calculations: I did not have any calculations. The only thing I needed to do was count the number of apples it took to tear the paper towel. Results: The more expensive brand (Kleenex Viva) turned out to be the strongest. The least expensive brand (Topcrest) turned out to be the weakest. The second most expensive brand (Bounty) turned out to be strong, but it was not as strong as the most expensive brand. The more expensive brands turned out to be about 3 times stronger than the least expensive brand. Conclusion: My hypothesis is correct.
The more expensive brand turned out to be the strongest. My results did vary a little bit because the apples were not all the exact same weight. It was hard for me to hold the paper towel while placing the apples on top of it by myself and I needed assistance for my results to be more accurate. I dont think that I needed repeat my experiment, but I did need a more constant and accurate way of measuring how strong the paper towel is. Now I know that it is worth the extra money to buy the more expensive brands of paper towels.
