Utilizing the method that the experimenters have come up with, the procedure isolates the variable being tested, which is the paper towel brand. By not changing other aspects of the procedure, other factors have a lower chance of affecting the accurate results of the answer to the main question. Additionally, the method is a quick and simple experiment, causing no use of excessive time than the provided duration. Within the first minutes of the experiment, the experimenters and the advisor realized that the method did not really provide accurate results due to merely estimating the numbers without the use of a graduated cylinder. Changing that aspect of the procedure by using a graduated cylinder to measure the amounts of water instead helped …show more content…

The control group contains 200mL of water, 28.6cm by 17.8cm size of paper towel, the amount of folds to the paper towel, same cup used to put paper towel in, ten seconds to soak paper towel in water, ten seconds to take paper towel out and let it get drip off excess water, and a graduated cylinder used to measure amount of water. On the other hand, the experimental group includes all the same components of the control group, but it adds the factor of changing the paper towel brand. The controlled variable has all the same aspects as the control group and the manipulated variable is the change in paper towel brand. After the procedure finishes, the responding variable represents the amount of water the paper towel absorbs, which is measured using the graduated cylinder. To start off the procedure, the experimenters must first grab the Kirkland paper towel and rip off a 28.6cm by 17.8cm section, which is its given measurements for each piece of paper towel. Second, the experimenters has to fill up a measuring cup until the water reaches 200 mL. Third, the experimenters will fold the paper towel in half three …show more content…

Fifth, once the paper towel is entirely in the water, count ten seconds and then take it out. After taking it out, put the wet paper towel over the cup and wait ten seconds in order to get rid of excess water. By putting it over the cup, the excess water falls into it, so that the result of how much water the paper towel absorbs remains accurate. The sixth step is to put the wet paper towel aside and take the cup and pour the leftover water into a graduated cylinder. During the pouring process, the water might cling to the sides of the graduated cylinder, decreasing the initial value. However, it does not affect the measurements by a drastic amount and only by a tiny bit. Next, the experimenters will decipher how much water is left and subtract the original amount, which is 200 mL, by the milliliters of water left in the cup in order to calculate how much the paper towel really absorbed. Finally, record the data and repeat with the same paper towel brand until there are three trials and then change the paper towel brand, in this case, to Tork and repeat procedure for another three
