The purpose of this experiment is to find out which brand of paper towel, Decorator or …show more content… The process was then repeated for the second brand of paper towel. Cardboard tubes, paper towel rolls, TP rolls, toilet paper rolls, wrapping paper rolls, you name it! Test claims of manufacturers to determine what brand of paper towel stands up to its promotional material. I put 3 plastic cups in front of Lorelai – 2 filled with water, 1 empty. For instance, if one brand of paper towel advertises itself as the strongest, your hypothesis could read, "Brand X is the strongest wet paper towel." We also had to figure out what aspects of the experiments we should keep constant. Observe the water moving up the paper towel.

Stick one end into one of the colored waters, and the other end into the empty middle cup. Of the two brands that will be tested, the Sparkle brand will absorb the most liquid because it has the “thirst” pockets and will be the strongest because it feels thicker. The dependent variable was the absorbency and strength. Scientific Method Lab: Paper Towel Posted on September 12, 2012 by Mr. Saleh Students will investigate four different types of paper towels to determine which paper towel is …

The water moves up the paper towels through a process called capillary action. The key difference between the scientific method and other ways of acquiring knowledge are forming a hypothesis and then testing it with an experiment. We were way overdue for a fun experiment, so this morning I broke out the materials for a paper towel experiment that I saw on Pinterest. The purpose of this experiment is to find out which brand of paper towel, Decorator or Sparkle, is stronger and more absorbent. Exploring the Scientific Method . Some of the STEM challenges will require a whole bunch, some just a few, and some just one! Plan and implement simple experiments to determine which brand of paper towel is the “best buy.” Use tools like mass weights, droppers, measuring spoons, and graduated cylinders to calculate accurate measurements.

Scientific Method Lab: Paper Towel Posted on September 12, 2012 by Mr. Saleh Students will investigate four different types of paper towels to determine which paper towel is … Roll a paper towel into a tight tube. The gaps in the paper towel act like capillary tubes and pull the water upward. It absorbed on average, 50ml of water, when the Bounty brand paper towels absorbed only 44.75ml of water. WANT TO KNOW MORE: What is STEM? The brand of paper towels (cause) affect the amount of water absorbed (the effect). Repeat for the other side, so that each cup has a paper towel that ends up in the middle cup, as seen above. Students in science classes often start off the first chapter with that familiar step-by-step flow chart showing how scientists develop a hypothesis, test a hypothesis, gather data, and then draw conclusions.

Method Fill the beaker up with exactly 200 ml of water Take a sheet of the first brand of towel.

Fold and insert into the water. If it’s a tube-shaped piece of cardboard, it will work perfectly for these cardboard tube STEM activities. Children will soak up science concepts with this water table activity. The original purpose of this experiment was to see which paper towel brand would be the most absorbent for consumers’ needs. Ours took a while to get down into the other cup (like 30 minutes).
