1. Problem Statement
Which paper towel is the most absorbent?

2. Variables Responding Variable:
Constant Variables: Water Tray Cups Graduated cylinders Funnels
Manipulated Variable: Sparkle, Bounty, Publix, Brawny, Bounty Basic, and school paper towels
Responding Variable:
Amount of water each paper towel holds

3. Hypothesis
If we test which paper towel is the most absorbent, then Bounty will be the most absorbent.

4. Materials Sparkle cups Bounty graduated cylinder Publix funnel Brawny
Bounty Basic
school paper towels
Water
tray

5. Procedures Pour water into the tray.
Place the paper towel in the water.
Pick up the paper towel, then squeeze the water into the cup.
Pour the water from the cup into the funnel that is sitting on top of the graduated cylinder.
Record the number of milliliters that the paper towel absorbs.
Repeat the experiment 2 more times and find the average.

6. Data Number of Milliliters of water 28 26 53 36 21 27 17 8 18 24 51 60
Trial 1
Trial 2
Trial 3
Average
Bounty Basic 28 26 53 36
Sparkle 21 27 17
School 8 18 24
Bounty 51 60 49
Publix 31
Brawny 45 25 40 37

8. Results
Our average results in order from least amount of water to greatest amount was school, and Sparkle were tied with 17ml of water. Publix had 24ml and Bounty Basic had 36ml. Brawny had 37ml and Bounty had 53ml.

9. Conclusion
Our hypothesis was supported by this experiment. Bounty absorbed the most water by far. Surprisingly, Sparkle and school were tied, we thought Sparkle would be better. Maybe Bounty absorbed the most because of its design and layers. It was very thick so maybe that’s why it was more absorbent.

10. Application
This experiment is helpful if you spill any liquid. Now we know that Bounty is the best paper towel to absorb spills. In the future we could repeat the experiment with different brands such as Scott, Kirkland, or Great Value. We wonder what brand will win in that experiment.

12. Abstract
The purpose of our project was to learn which paper towel was the most absorbent. We thought that Bounty would absorb the most water. We put the paper towels in water and then squeezed the water from the paper towel into a graduated cylinder and measured it. Bounty was the most absorbent. Sparkle and school were the least absorbent. Our hypothesis was supported by this experiment. When we spill something that is liquid, we now know to use Bounty because it’s the most absorbent. Our project could be improved if we repeated it using different paper towels or different liquids.
