The purpose of this experiment was to see which brand of paper towel most absorbent for consumers.
I became interested in this idea when I got looking on the Internet for project ideas.
The information gained from this experiment can help consumers know
which paper towel will absorb the most of their everyday spills.
Hypothesis
1.My hypothesis is that Bounty Paper Towel brand will absorb the most liquid compared to four other brands of paper towel.
2.I base my hypothesis on the research that I did on the Internet that
said that Bounty paper towel is 20% more absorbent than other leading paper
towels.
Experiment design
The constants in this study were:
1. The size of each brand of paper towel
2. The amount of water that will be in the beaker in each test.
The manipulated variable was the different brands of paper towels.
The responding variable was the amount of water that will be in each beaker.
To measure the responding variable I will measure how much water I squeeze
out of the paper towels into the graduated cylinder, I will measure in
milliliters.
PROCEDURES
1. First gather all of the materials that you need.
2. Then pour 200 milliliters of water in the beaker that you have.
3. Place a round funnel on top of the graduated cylinder.
4. Then take the first brand of paper towel on your list and place
it in the beaker.
5. Time for 15 seconds.
6. After 15 seconds, take the paper towel out of the beaker.
7. Squeeze all the water out of the paper towel into the graduated
cylinder.
8. Record how much water is in the graduated cylinder.
9. Take the amount of water that was poured into the graduated cylinder
and subtract that from 200 milliliters.
10. Next, try the test with 4 other brands of paper towels.
11. Each paper towel needs to be tested 4 times, but you need to record
your data for each paper towel on your data table.
12. Make sure that the water doesn’t spill in any of the tests or you
will have to restart the tests over.
13. Record all data on your data sheet.
Results
The original purpose of this experiment was to see which paper towel brand would be the most absorbent for consumers’ needs.
The results of the experiment were that the Sparkle brand paper towels were the most absorbent. It absorbed on average, 50ml of water, when the Bounty brand paper towels absorbed only 44.75ml of water. Western Family brand paper towels absorbed 34ml of water on average, and Scott brand paper towels only absorbed 33ml of water.
Conclusion
My hypothesis was that Bounty paper towel would be the most absorbent.
The results indicate that my hypothesis should be rejected because sparkle paper towel was the most absorbent out of the four test groups.
Because of the results of this experiment, I wonder if next time that I do an experiment that maybe I will need to do more test groups.
My findings should be useful to consumers because now they can use my information to know which brand of paper towel can absorb the most of their everyday skills.
If I were to conduct this project again I would use more test groups
and I would use different test groups to see if there are paper towels
that are more absorbent than Sparkle paper towel.
