Paper Towel Experiment Lab Report

The purpose of this experiment is to find out which brand of paper towel, Decorator or Sparkle, is stronger and more absorbent. Of the two brands that will be tested, the Sparkle brand will absorb the most liquid because it has the “thirst” pockets and will be the strongest because it feels thicker. Materials and Methods For the first experiment we did the test for strength. We used a 600 ml beaker which we placed the sample paper towel over the opening of the beaker.

The size of the sample towel was 234 mm. The paper towel was held it in place with a standard rubber band that was wrapped around the top of the beaker one time.

We then took 5 ml of water and poured onto the paper towel. The weights that we used were 27 g each. The weights were placed on the paper towel one weight at a time until the paper towel ripped.

The total amount of weight that it took to rip the paper towel was recorded. The process was then repeated for the second brand of paper towel. For the second experiment we did a test for absorbency. We used a graduated cylinder which was filled with 100 ml of water. The paper towel, which was . 34 mm, was immersed into the water for 15 seconds. The paper towel was removed from the water and allowed to drip until the drips were 25 seconds apart.

At that time, the amount of water that was left in the cylinder was recorded.

The difference in what was left and the amount that was originally in the cylinder is the amount of liquid that each paper towel held. The process was then repeated for the second brand of paper towel. The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of he paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.

Results The results of the experiment for the test of strength were that the Sparkle brand proved to be the strongest. The average amount that the paper towel would hold before ripping was 583. 6 g, which was 159. 2 g more than the Decorator brand held. The Decorator brand only held 424. 4 g before it ripped. The results of the experiment for the test of absorbency were that the Sparkle brand proved to be the most absorbent. The average amount of liquid that the Sparkle brand paper Lowell held was 17. 4 ml which was 4. 6 ml more than the Decorator brand held.
