Paper Towel Experiment Essay

Bounty seems to be more absorbent because it has tight stitching, which creates a larger surface area than other paper towel brands. This means that there is a larger amount of cellulose fibers in Bounty paper towels. Bounty is also thicker and softer than both the Sparkle and Dutch Fork High School paper towels, which are major factors that play into the absorbency of a paper towel. Based on this research the hypothesis was if Bounty, Sparkle, and Dutch Fork High School paper towels are tested for water absorbency, then Bounty will absorb the most water since it has the greatest absorbency factors out of the three brands. There is constantly new paper towels being created and promising that they are more absorbent than others, but the only way people will know is by testing them out, which is why this experiment was conducted. In this experiment, the independent variable is the different brands of paper towel. The dependent variable is the amount of water each brand of paper towel absorbs in thirty seconds. The constant variables are the amount of water the paper towels are in, the amount of time the paper towels are in the water, the amount of time the paper towels are allowed to drip after being taken out of the water, and the tool used to measure the amount of water

The independent variable in the experiment was the mass (or amount) of the cheese and bacon balls.

Paper towels are known for their absorbency. These towels are made of paper and are attended to be used once. Paper towels are used for cleaning and dry a variety of surfaces. During this lab, my group observed several brands of paper towels. Those brands included our school paper towels, Viva Vantage, Best Choice, and Bounty Basic. Our school paper towels were around 800 square feet long, had an average cost per roll of $5.25, and was single ply. This paper towel was brown in color, rough in texture, and dotted in pattern. Viva Vantage had 59 sheets per roll, had an average cost per roll of $2.09, and was single ply. The Viva Vantage was soft in texture, white in color, and had to apparent pattern. Best Choice had 111 sheets per roll, had

With these absorbance numbers a concentration curve was constructed and the unknown solution was determined by finding the point of absorbance on the curve.

The question was “What kind of bubble wrap would protect an egg the best. A hypothesis sprouted out of the question: If the 195 bubble wrap (which had the largest bubbles) is used then the egg will be the most protected.This experiment was done on December 30, 2016. The independent variable for this experiment was the type of bubble wrap used to wrap the eggs. The dependent variable is whether or not the egg cracked. Whether or not the egg cracked was affected by how well it was protected. Some of the control variables that are in the experiment are, the height the eggs are dropped at. The brand of eggs used is another control variable. The control group were the eggs that were not wrapped in any bubble wrap. To conduct this experiment one egg was wrapped in one of the sizes of bubble wrap. The bubble wrap had a length of 81.28 cm., and a width of 19.28 cm. After the egg was completely wrapped it was dropped from a height of 1.7 meters. These steps were repeated three times for every kind of bubble wrap used.

Three paper towels A, B, and C where tested on absorbency. This experiment was tested twice. Paper towel A was 26.5 by 28 centimeters. Paper towel B was 26.5 by 28 centimeters. Paper towel C was 15 by 28 centimeters. Scissors were obtained and each paper towel was cut to 13.5 by 15 centimeters. The weight of the three paper towels at this size was 0.9 grams dry for paper towel A, paper towel B weighed 0.8 grams dry, and paper towel C weighed 1.2 grams. Three beakers weighing 12.2 grams each were obtained. Each beaker was filled with 100ml of water with the outcome of them weighing 128.1 grams each. The weight of each paper towel dry was deducted from the weight of each paper towel. Paper towel A was left to soak for seven seconds.

Absorbency affects: skin comfort, static build-up, dimensional stability in water, stain removal, water repellency, and wrinkle recovery.

The ending result of this experiment confirms that as five test tubes are lined up with the varying level of absorbance, different results in the level of absorbance will appear as well, this is visible in above table. Thus, this is due to the varying amount of water in the solution. The blank sample had a 0.30 in its level of absorbance.

The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of the paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.

The topic is: The cleanest cleaner. In this experiment, the scientists will be testing which brand of detergents cause a better cleaning effect on one stain on multiple white shirts. The independent variable in this experiment consists of the different detergents, while the dependent variable consists of the amount by which the stain faded (using the purple light scale), and or removed, others include the white t shirts, washing cycle, and drying cycle, staining agent, and cycle of drying and washing. The control variable in this experiment will be the 1 trial run with water only per experiment. The unit while measuring the amount of detergent is mL, and a scale which the is going to use to measure the amount of stain faded.

For this experiment, the amounts of Red 40 and Blue 1 were quantified in six different Kool-Aid samples through the use of a spectrophotometer. This was completing by performing serial dilutions on both dyes, Red 40 and Blue 1, and then creating calibration curves for each of the six samples. The absorbance and maximum wavelength values were obtained from the spectrophotometer for each individual drink sample. Beer’s Law was used to discover the concentration of

The research question for the Alka Seltzer Lab is, “What is the effect of different surface areas of an Alka Seltzer tablets reaction time?’. Inside of an Alka Seltzer tablet there are two key ingredients; which are citric acid and baking soda. When a tablet is dropped into a liquid, the acid and baking soda show a physical reaction of fizzing and eventually dissolving. Materials needed for this lab was goggles, aprons, beakers, water of the same temperature, mortar pestle, and three alka seltzer tablets. In each beaker there was 150 mL of water. The first tablet was a full tablet, the second was broken into quarters, and the last tablet was crushed in a mortar pestle. The dependent variable of the lab was the rate of reaction, and the independent

My science fair topic is “Which beverage stains your teeth the most?” and I chose that topic because my family drinks a lot of different beverages and we disagree on which drinks stain your teeth. The main question that I am attempting to answer is which beverage coffee, tea, soda, or grape juice stain your teeth the most. To do this, I plan to test each beverage on egg shells for five days. To monitor the beverages effect on staining teeth. The information in the following research paper will provide answers to the following research questions: 1) What beverage stains your teeth the most? 2) How does this beverage stain your teeth? 3) Is there a way to prevent staining to your teeth?

The absorbance is measured using a Plate reader and a Standard curve is generated. Also, the different types of pipetting techniques are assessed in this Assay.

And brown paper was used to detect any lipids found in the sample. After drying, the towel becomes opaque as a negative control and translucent for the positive control.
