The Paper Towel Lab
Background:
Paper towels are in almost every household in the U.S. Each year over 13 billion pounds of paper towels are used in this country. This means the average person uses over 43 pounds of paper towels each year. Paper towels are part of daily life: it’s important to know which brand is the best. It’s especially important to know which is the best to use, considering that paper towel factories have huge carbon emissions, due to the large amount of energy needed to manufacture them. With many brands creating slogans and commercials to tell you their brand is the best brand, it is increasingly difficult to chose the right paper towel. For example, Bounty says they’re “the quicker picker upper”, while Viva Vantage says “more people prefer Viva Vantage over Bounty.”

Hypothesis:
I hypothesize that paper towel brand #4 will pick the spill up the fastest. It is the thickest paper towel: there may be more layers within it. Because of this quality, …show more content…
Brand #3 — revealed to be Viva — throughout the 3 trials took the least amount of time to pick up the spill. Viva triumphed over what many people would believe the best paper towel brand, Bounty. One source of error in the experiment was the lack of precision in measuring water. To improve the experiment, I could have used a special pipette that would measure more precise volumes of water. A second source of error was in introducing paper towel to the water. While placing the paper towel down onto the water, the amount of force I used varied for each trial. To combat this, a mechanism that applies equal force down onto the paper towel each time could have been used. That Brand #4 and Brand #2’s lines on the graph are rather erratic indicates that these known sources of error may have affected the
