Paper Towel Absorbency

By: Skylar Crooker

Purpose Statement:

The purpose of this experiment is to find out which brand of paper towels absorbs more water.

Background Research:

Paper towels are made up of cellulose fibers which also make up cotton, wood, and most other plants. These cellulose fibers are actually giant molecules that consist of many small molecules linked together. The small molecules that combine to make up cellulose are sugar molecules; that’s the key to the absorbency of paper towels. When you get a paper towel wet, the water molecules rush in and cling to the cellulose fibers. That’s why paper towels are great at picking up spills.

Hypothesis:

My hypothesis is that the paper towel brand Sparkle will clean up the mess faster and better because it has pockets on it and when you wipe it up I think that the water will go up in the pockets.


Materials:

  • 3 different brands of Paper towels: Sparkle, Bounty, & Target brand

  • A stopwatch

  • A beaker

  • A graduated cylinder

  • A funnel


IV: Brand of Paper Towel

DV: How much water the paper towel absorbs

CV: Amount of Water in beaker & time paper towel left in water

Procedure:

  1. Fill the beaker up with exactly 200 ml of water.

  2. Take a sheet of the first brand of towel.

  3. Fold and insert into the water. As you dip the towel into the water, start the stopwatch.

  4. After 20 seconds, remove the towel from the beaker and squeeze as much water as you can out of the towel into the graduated cylinder using the funnel. Make a note of the volume extracted.

  5. Repeat steps #1-4 2 more times.

  6. Repeat steps #1-5 with other 2 brands of paper towel.

Conclusion:

My hypothesis was that the paper towel brand Sparkle will clean up the mess faster and better because it has pockets on it and when you wipe it up I think that the water will go up in the pockets. Based on the results of this experiment my hypothesis was incorrect. The brand Bounty paper towels absorbed more water.
