Questions
A grоup оf high schоol students cаme up with аn experimentаl design to measure which type of paper towel is the strongest. They purchased a store brand paper towel and a name brand paper towel. They labeled the store brand as "Paper Towel A", and the name brand as "Paper Towel B". They also purchased distilled water to use in their experiment. While in the lab, they placed 1000 mL of distilled water in two graduated cylinders, and labeled them "Cylinder A" and "Cylinder B" to coincide with the paper towel labels. One sheet of each type of towel was placed over separate empty 500 mL beakers and secured with Staples #19 rubber bands. They slowly added single drops of water from cylinder A onto paper towel A until the paper towel was torn. They then placed the remaining water left in the dropper back into the prospective cylinder A and measured the amount of water still remaining in the cylinder. The same was done with paper towel B and cylinder B. Their conclusion was that the store brand paper towel is stronger, because cylinder A contained the most amount of water. Which of the following is the DEPENDENT variable in this experiment?
