The Strength of Toilet Papers
Collect It!
Aim: To test and record the strengths of each brand of toilet paper.
Hypothesis: That the more expensive the brand, the stronger the toilet paper.
Variables:
The independent variable is the brands of the paper.
The dependent variable is the amount of weights.
The controlled variable is the amount of water, the size of paper used.
Materials:
* 3 brands of toilet paper
* Water
* Dropper
* 1 beaker
* Rubber band
* Small weights ~ 3.38g
Method:
1. Roll out one section of each brand of toilet paper.
2. Position first brand of paper so that the middle section is covering top of beaker.
3. Place the rubber band around beaker to hold paper in place.
4. Use dropper to wet the middle of the paper with 0.6 mL of water.
5. Begin placing weights on the dampened section one at a time.
6. Continue placing the weights on until the paper breaks and coins fall into the beaker.
7. Record data into table.
8. Repeat the experiment 3 times for each brand.
Diagram:
Results:
| Trial 1 | Trial 2 | Trial 3 | Average |
Home brand $3.80 | 4 | 6 | 10 | 7 – 23.66g |
Naturale $6.12 | 5 | 12 | 11 | 9 – 30.42g |
Sorbent $10.00 | 13 | 21 | 25 | 20 – 67.6g |
Discussion:
The results were recorded and observed. It was found that the more expensive the brand, the more strong and durable the toilet paper is. Home brand was tested through 3 trials, the paper was wet with a 0.6ml of water through a dropper and was able to carry an average weight of 7 weights. Naturale was also tested through 3 trials and was able to carry an average of 2 more weights than Home Brand. The most expensive brand, Sorbent was able to carry more than double the amount of Naturale at 20 weights weighing at 67.6 grams.
All brands experimented were 2-ply and each of the paper brands had a different texture, which may have affected the strength and durability after being dampened by the water. Home...
