ABSTRACT: You always see on paper towel commercials comparing its product to other companies to see which paper towel is most absorbent. I decided to take the problem into my own hands and figure out which paper towel brand is really the most absorbent.
PROBLEM: Figure out which paper towel is most absorbent.
HYPOTHESIS: I believe that the store brand will be just as or more absorbent then name brand paper towels, such as Bounty or Brawny.
LIST OF MATERIALS:
Four brands of paper towels, one being store brand
2 small bowls
liquid measurer (10 mL)
sharpie and pen
water & food coloring
Step 1- Take one sheet of the first paper towel, make adjustments to make sure all paper towel sheets are all equal in size. (different brands sometimes have different size sheets.) Place the paper towel on a flat surface.
Step 2- fill up one small bowl with water and add food coloring.
Step 3- Fill up the water dropper all the way to the 10 mL mark from the water in the bowl. Make sure its all the way full for each time you fill it up.
Step 4- Release the water onto the paper towel.
Step 5- Repeat step 3 and release the water again onto the same paper towel. (20 mL for each paper towel.)
Step 6- Wait 30 seconds for the water to absorb.
Step 7- Pick up the paper towel and squeeze it into the second bowl.
Step 8- Fill up the water dropper with the liquid in the second bowl and measure in mL how much it absorbed. Record your results.
Step 7- Repeat steps 2-6 for other three brands of paper towels.
EXPERIMENTAL DESIGN DOCUMENTATION
- Above are all four of my expiremental groups; Bounty, Brawny, generic brand, and Viva.
|Bounty||Brawny|| Generic Brand||Viva|
| 7.5 mL|| 5.5 mL|| 9.0 mL||6.0mL|
EVIDENCE OF AUTHENTICITY: INSERT CLEAR PICTURES/VIDEOS OF YOU DOING THE EXPERIMENT
- After 20mL was applied to first paper towel
-Squeezing the water from paper
-Measuring the absorbed liquid from paper towel 1
towel one into the second bowl
- The generic brand absorbed the most liquid.
DATA ANALYSIS: I found that Bounty absorbed 7.5 mL of the 20 mL, Brawny absorbed 5.5 mL of the 20 mL, the generic brand absorbed 9 mL or the 20 mL, and Viva absorbed 6 mL of the 20 mL.
CONCLUSION: After my experiment, i found that the generic brand clearly absorbed more then any of the other brands. Proving my hypothesis to be correct.
