Paper Towel Inquiry Lab
Shayla Shigematsu Mrs. Nofzinger Chemistry 18 June 2013 Purpose: We are trying to ﬁgure out which paper towel soaks up most water because it’s always nice to know which paper towel brand you should buy because you would want to know which paper towel is the most effective. Hypothesis: If we use the ology paper towel it will soak up the most water because it is bigger and compared to “tuff” which is the same size, it is thicker as well. Materials: • Paper towel • Water Equipment: • Beaker that can ﬁt 300 mL • Any beaker • Graduated cylinder Procedure: 1. Tear off one piece of paper towel from the paper towel roll 2. Fill a beaker with 300 mLs of water 3. Soak the paper towel in the water-ﬁlled beaker 4. Squeeze the soaked paper towel into the empty beaker 5. Pour the water from the beaker into the graduated cylinder and measure Data: Type of paper towel Ology Nice Tuff Sparkle 60 mL 30 mL 40 mL 50 mL Trial 1 5.4 mL 5.2 mL 4.8 mL 6.6 mL Trial 2 Trial 3 36.2 mL 26.2 mL 17.2 mL 26.6 mL

Trial 3

After we tested the paper towels we found out that we were correct on our hypothesis. Ology worked the best for soaking up the water. 2 out of 3 of the trials we did proved that ology soaked up the most water. Compared to the other paper towels, ology soaked up at least 10 more mLs of water than the other paper towels. I think that there is a positive correlation between the cost and quality because the more the paper towel costed, the more efﬁcient it was. The two most expensive ones were ology and sparkle. The ology paper towel sheets soaked up more than tuff even though it was the same size. And Sparkle soaked up more than nice and tuff even though it was only half the size of ology. I would recommend sparkle to people. Even though it doesn’t pick up as much as ology, it’s about 10 mLs away which is pretty close especially because sparkle is only...
