  3. Introduction:
  4. In this experiment our hypothesis was “On a per unit area basis, some brands of paper towels are more absorbent than others.” Using this we formed an experiment to determine which of our three paper towels was the more absorbent as well as the most likely more expensive brand based on the results.
  5. Materials:
  6. • Brand A paper towels
  7. • Brand B paper towels
  8. • Brand C paper towels
  9. • Scissors
  10. • 100mL measuring cylinder
  11. • Measuring cup
  12. • Forceps
  13. • Funnel
  14. Method of Experimentation:
  15. We noticed that Brand A of the paper towels was slightly smaller than the other brands so we used scissors to cut every paper towel to the same size to assure accuracy in our tests. After that we folded our paper towels three times into a small square big enough to fit into the bottom of our measuring cup. Next we filled our measuring cylinder up to the 40mL line and then transferred the water into the measuring cup. We then placed the paper towel into the water for ten seconds to allow absorption to take place. Following the ten second wait we used the forceps to pull the paper towel out of the cup. Using the water left over in the cup we poured it back into the measuring cylinder to see how much was left. This is how we got our data. We used this process three times for each brand of paper towels to get a somewhat accurate average of the absorption for each brand.
  16. Results:
  17. Our results show that Brand A had the best average absorption of 27mL per 40mL of water. Brand B had the second best average at 18mL per 40mL of water. Finally Brand C had the worst average with 14mL per 40mL of water.
  18. Conclusion:
  19. We can safely conclude that Brand A obviously absorbs more water per paper towel than the other given brands and is most likely more expensive. Our results support our hypothesis and we could replicate this experiment again and again with the given results. The experiment demonstrated with ease the absorbent qualities and should not be changed at all and was not flawed in any way.
