Which Paper Towels Has The Best Absorbency? By James Gilmer Project Design Plan To determine which paper towel has the greatest absorbency. Paper towels were first introduced for the Scott Paper Company of Philadelphia to help prevent the spread of colds from cloth towels in bathrooms (Corkhill & Seder 2008). Paper towels are constructed of giant molecules consisting of smaller molecules of cellulose fibers (Brown 2013). The smaller molecules are made up of sugar molecules, which is the key to the absorption of paper towels. Literature Review There are multiple brands with each brand having different types of paper towels that vary in price that are sold in stores. Consumer Reports rated Bounty has the top paper towel for absorbency, …show more content…
The cylinder will be dried out after each turn 7. After 8 turns, drop the highest and lowest and divide by 6th to get the average Tools and Technologies Paper Towels Water Measuring Cup Funnel Graduated Cylinder Stop Clock Variables Independent Variable = Different paper towel brands Dependent Variable = Measurement of water in graduated cylinder Controlled Variables = Amount of water; Time in water; Squeeze of paper towel Threat reduction to internal validity By using a purchased gallon of water ensures that the same water is used for each paper towel. By thoroughly drying the funnel and graduated cylinder each time helps ensure the exact measurement. Using the exact same squeezing technique helps ensure that one wasn’t squeezed harder than the other. Hypothesis The hypothesis of this experiment is that Bounty will be the most absorbent based on others reporting their own experiments of paper towels.

Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.
Half fill the ... ... middle of paper ... ... e data quality. Furthermore, using a graduated cylinder with markings below the 100 mL line would have allowed for more accurate measurements of the initial volume of air in the graduated cylinder.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
In 105 CE a man named Cai Lun during the Eastern Han Dynasty invented the paper from worn fishnet, bark and cloth. These materials were used because they could be easily found at a low price compared to Hemp fiber and silk. Hemp fiber and silk were used at first but then the Chinese realized there are greater uses for this material. Therefore they started to use the worn fishnet, bark and
The materials used in this experiment included paper and straws, both very light materials. I wonder if similar results could be obtained with other materials such as carbon fiber or aluminium. Since gravity is constant, (9.8 m/sec/sec), I would be interested to learn if paper's air resistance while flying allows for produced greater or lesser distances than would carbon fiber or aluminum with the same wing to body
To see which name brand of hand sanitizer will work the best in disinfecting bacteria and mold. This experiment will show people which hand sanitizer works best to stay disinfected when there is no access to soap and water when needed.
I also stock the linen closet. Every patient who lies on the big brown therapy table has to be on a sheet with at least 2 or 3 towels nearby. The towels feel rough and course from years and years of reuse. Everything gets the ammonia treatment, including the silver parallel bars, the whirlpool and the giant rubber gym balls that are used with patients who have bad backs.
Proctor & Gamble understands the high competition that already exists in the toilet paper industry, but feel that new Bounty Toilet Paper will change how this industry is geared. In recent times, toilet paper producers have stressed comfort and style in the production of their products, but as the times have changed, the American public is now more interested in getting the job done in the shortest amount of time with the smallest amount of the product. P&G have produced Bounty Toilet Paper because of this change in the lifestyle of Americans. With this focus on effectiveness and durability, Bounty will go into the new Millennium leading the toilet paper world.

With a partner, simultaneously lower the straws into each of the graduated cylinders. When the straws reach the bottom of the cylinder each partner will place an index finger over the opening of the straw and then transfer the contents to the opposite graduated cylinder and allow the water to drain.

present at all times but it must retain some of them. All plant life on Earth benefits from the ability of water to make a hydrogen bond with another substance of similar electronegative charge. Cellulose, the substance that makes up cell walls and paper products, is a hydrophilic substance ("water-loving"). It interacts with water but, unlike other hydrophilic substances, it will not dissolve in it. Cellulose can form strong hydrogen bonds with water molecules. This explains why a paper towel will "wick" water upwards when it comes in contact with it.
Background Research: The weight of printer paper is 1.8 grams per sheet. Cardstock weighs in at 199.6 grams per sheet. While construction paper weighs the total of 68.9 grams. Three important characteristics that contribute to making a good plane is the weight of the material, the stiffness of the material, and the texture of the material. Having curved wings also improves air dynamics since having them curved make the air go over the wings faster, resulting in an upward motion.
