Which paper towel is the most absorbent? Our 6th-graders found out!
The sixth-graders are learning about the methodology of science, which is how we draw conclusions from observations. To solidify this concept, Mr. Landis held a controlled experiment for students to find out, “What is the most absorbent paper towel brand?” between Viva, Bounty, Great Value, and Sparkle.
Controlled experiments have three variables: the independent variable (also known as the manipulated variable), the dependent variable (also known as the responding variable), and controlled variables.
The size of paper towels, water temperature, and materials were all controlled as best as possible. Each towel was submerged in water for five seconds, held up for 15 seconds, and then squeezed for 10 seconds into a graduated cylinder through a funnel. Students then measured the amount of water extracted from each paper towel sample. The experiment was repeated several times and then students were able to analyze their data.
As it turns out, Viva is the most absorbent paper towel. Now, does price influence your choice? Let us know so we can tell our sixth-graders!
