1 Which Brand of record Towel Is The many Absorbent?By: buy it Davidson Mr. Baker sixth Period – November 2011

2 brand of file Towels Bounty Brawny Viva through Kleenex Colortex

3 my Hypothesis based upon my research, ns think the the Bounty file towels will certainly be the most absorbent. I learned the the absorbency of document towels is based upon the plies (some are 1-ply, others space 2-ply and also typically, the greater the ply, the greater the absorbency rate), creping, and embossing. Creping is once the fiber-to-fiber bond in the document towel are separation up. Embossing is when the surface ar of the file towel is readjusted from a flat to shame surface. The is why there are patterns/designs within the file towel; the elevated areas enable there come be much more room because that the water to flow through the towel and be absorbed. Companies execute these procedures differently, and that is why the brand have different absorbencies. The Bounty record towels space 2-ply, and also have a high price of creping and embossing.

4 Variables In This ExperimentControl Variable: The fluid being took in (water) and also the amount of water initially in the measure up cup room the control variables in this experiment. Elevation Variable: The independent change is the brands of document towels gift used. Dependency Variable: The dependent change in this experiment is the amount of fluid each file towel absorbed.

5 Materials In this experiment, you will certainly need:Different brand of record towels (In this case: Bounty, Brawny, Viva, and also Colortex.) A measure up cup Water A trash can paper and pencil (to take notes)

6 My procedures Take one paper towel from each of the different record towel rolls. Make sure they space the same size—use two half-sheets to equal a whole sheet. Utilizing the measure cup, measure the end 6 ounces the water. Location one the the paper towels every the means into the water and let the absorb as lot as that can. Then, take it the file towel the end of the water, and throw that away. Make note of what brand of file towel that was and also how lot water is still in the measure up cup (subtract the amount left in the cup indigenous 6 ounces and you will get how much water was absorbed). Pour out the staying water, and fully dry out the measure cup. Repeat these actions for each brand of paper towel. To compare notes—see which paper towel absorbed the many amount of liquid.

8 mine Conclusion In conclusion, my theory was correct; the Bounty file towels room the most absorbent (It was additionally the most expensive.). Comes close behind to be the Brawny towels, by just .03 ounces that difference. I realized the the embossing markings and also the thickness of the document towel were important in identify the absorbency. Over there were plenty of problems through this experiment, such as the water dripping off of the record towel earlier into the measure cup after I had actually taken it out. If ns were to command this experiment again, i would uncover ways to stop this—I would shot to move more quickly in throw the document towels away. Also, I can use an ext brands of paper towels and more trials to help get more accurate results.
