2. Problem Statement What brand of paper towel is the strongest?
(Title: Revenge of the paper towels!)

3. Variables
Constant Variables: Pennies Graduated cylinder Tray 30ml of water Cup
Manipulated Variable:
Brands of paper towel
Responding Variable: What brand of paper towel is the strongest?

4. Hypothesis:
If we test Bounty, Family Values, Sparkle, Clear Value, and the school’s paper towel, then Bounty will be the strongest.

5. Materials Pennies Bounty paper towel Sparkle paper towel
Family Values paper towel
School’s paper towel
Clear Value paper towel
30ml of water
Tray
Graduated cylinder
Cup

6. Procedures Pour the water into the cup.
Take a paper towel and fold it gently and put the entire towel underwater.
Take it out and squeeze out the excess water.
One person holds the paper towel while another person carefully, places one penny at a time onto the paper towel.
Be careful to count the pennies as you are placing them.
When the paper towel rips, subtract the last penny and record the amount of pennies the paper towel held, before breaking.
Repeat the experiment twice with the same paper towel.
Repeat steps 2-9 with the other brands of paper towels.

9. Data

10. Results
The school’s paper towel averaged 67 pennies. Bounty averaged 259 pennies. Sparkle averaged Family Values averaged Clear Value averaged 69 pennies. Finally, Kirkland averaged 191 pennies.

11. Conclusion
Our hypothesis was supported by the experiment. Bounty was the strongest out of all the paper towels we tested. We noticed that Family Values may have changed the way they held the paper towel and that may explain the large difference in their final results. Also, we had 22 people doing the experiment, so each group may have held the paper towel differently, close together or far apart.

12. Application
This experiment helps us in life because we know that bounty is the strongest paper towel of the 6 that we tested. We are going to show the data to our parents when we go to the grocery store. Therefore, we will tell them to get Bounty.

14. Abstract
We wanted to find out which brand of paper towel was the strongest. Our hypothesis was that Bounty would be the strongest of the 6 brands we tested. Bounty was the strongest of all the 6 brands of paper towels.
