The question is, “Which paper towel brand is the most absorbent?” The hypothesis is, “If a dropper drops water equally on a paper towel of each brand until it started to drip, then Bounty brand would contain the most water, in grams. The independent variable is the brands of paper towels. The dependent variable is the grams of water that was contained in the paper towel. The control variable was that every paper towel sheet was cut to be 15.2 centimeters by 28.1 centimeters. The control group was Brawny brand. The experimental group was Bounty, White Cloud, Homestore, Walmart Brand, and Sparkle. First, move one of the brand’s a paper towel sheets to a balance to see what the mass is. Then, take the dropper and drop water on the flat paper towel …show more content…
Each paper towel brand took the trial three times. Brawny’s first trial absorbed 28 grams,the second trial absorbed 31 grams, and the third trial absorbed 30.3 grams of water. The average was 29.77 grams of water. White Cloud’s first trial absorbed 22.5 grams, the second trial absorbed 22.9 grams and the third trial absorbed 23.6 grams of water. The average was 23 grams of water. Homestore’s first trial absorbed 16.4 grams, the second trial absorbed 18.2 grams, and the third trial absorbed 20.6 grams of water. The average was 18.4 grams of water. Walmart Brand’s first trial absorbed 17.6 grams, the second trial absorbed 16.9 grams, and the third trial absorbed 18.7 grams of water.

    Red 40 Dye Experiment

    For this experiment, a few scientists are researching how different flavors/colors of sports drinks effect the amount of red 40 dye in each drink. The independent variable in the experiment is the flavors of Gatorade (a brand of sports drinks) used, while the dependent variable is the concentration of dye the sports drinks contain. The constant variable is the spectrophotometer, the amount of liquid used, and the same type of cuvette. The controlled variable is only using water. In order to determine which drink would have the greatest concentration of red 40 dye, the scientists must first understand what it actually is.…

    The materials given were three raw chicken eggs, vinegar, maple syrup, tap water, and table salt. Prior to beginning the experiment, the raw chicken eggs were saturated in vinegar for two days, in order to remove the outer shell.

    Mystery Liquids Lab

    In this lab we wanted to identify what the four mystery liquids were using density and their characteristic properties. We were initially given four liquids that were labelled numbers 1- 4, some graduated cylinders, and a scale, but we also knew that the 4 liquids were ethanol, vegetable oil, water, and cyclohexane. Using the mass that we found when we measured the liquid and using only 10 mL of the liquids we were able to calculate the density and easily identify the liquids and see if they matched the guesses we had made initially. Our results do confirm our hypothesis that you could identify liquids if you have their densities.…
