hypothesis for which paper towel is the strongest

Wet Strength. Take a new sheet of paper towel off each roll and soak them with water. Repeat the weight test with your objects to see if water makes any of them weaker or stronger. Write down your results for each. Then, while one person holds the paper towel flat in the air, place one of the objects in the center of the wet paper towel--the ...

Take a sheet of the first brand of towel. Fold and insert into the water. As you dip the towel into the water, start your stopwatch. After 20 seconds, remove the towel from the beaker and squeeze as much water as you can out of the towel in to the graduated cylinder using the funnel. Make a note of the volume extracted.

The strength of a paper towel is among its most important properties. A stronger paper towel has more uses and will last longer. Another important property of a paper towels is its ability to absorb water. Almost all manufacturers of paper towels claim that their product is the strongest and absorbs the best.

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." Create a backboard that has some examples of the paper towels, pictures from the experiment, and the most important parts of the report, like hypothesis, conclusion, and important data, such as ...

If you find yourself short on time, testing which paper towel brand is the strongest, makes for a simple yet fun paper towel science project. Time Needed: 2 Hours. Materials Needed: 1 roll of Bounty paper towels 3 rolls of paper towels made by 3 separate brands. 1 large plastic tub 2 cups of water Notebook or journal Graph paper 125 quarters A ...

The penny paper towel experiment is a simple experiment that kids of all ages can do as they test whether a wet or dry paper towel can hold more pennies. Children can declare a hypothesis on which towel will be strongest, and then once completing the experiment, the students can record the data they discovered while doing the experiment.

If there is a difference in the number of drops absorbed, use the average value as the final for that brand of paper towel. Finally, repeat the above for each brand of paper towel selected. Method #2 - Capillary Action Method. When water is dropped on a paper towel, an immediate "spreading" of the damp spot is noticed.

Make five 10cm by 20cm rectangles for each brand of paper towels (Bounty, Viva, Kirkland, Sparkle). Fill the beaker with 250 mL tap water and use that water to fill the large cake pan. Put the rectangles of paper towels into the cake pan and start the timer. The rectangles of paper towels will stay in the water-filled cake pan for 15 seconds.

needed to determine which brand of paper towel really is the strongest. Background Information: Since paper towels are usually wet when they are being used, the "wet strength" of the towel is important. Wet strength is the strength of paper when it is wet. This can be measured by the amount of mass that a wet paper towel can hold.

The absorbency of paper towels experiment is an example of a factorial experiment. A factorial experiment consists of several factors (brand type, immersion time) which are set at different levels, and a response variable (weight of water absorbed). The purpose of the experiment is to assess the impact of different combinations of the levels of ...

Procedure: 1. Get a measuring bowl and put the same amount of water in it to wet the paper towel. 2. Place as many pennies on the wet paper towel until it starts tears. 3. repeat 5 times for each different paper towel. 4. When the paper towel rips count the pennies that were on the paper towel. Conclusion- After experimenting the strongest ...

Paper is made of cellulose, and water molecules like to cling to cellulose. As a result, paper readily absorbs water. Paper towels are especially absorbent. Their cellulose fibers have empty spaces, like tiny air bubbles, between them. Water molecules, which like to stay together, follow the water absorbed by the cellulose and fill up the empty ...

For example: If I soak three brands of paper towels in 200 mL of water for one minute, then Kirkland will absorb the most water. Notice how the "If" part of the hypothesis mentions the part the scientist has decided to change and is testing (we are testing the brands of paper towels), otherwise known as the independent variable. The "Then" part ...

Hi, The hypothesis is, as you mentioned, what you expect to happen. For example, you might hypothesize that a certain brand or type of paper towel will absorb the most water. To answer your other question, it might be helpful to come up with a clearer name for the experiment, such as "Investigating Water Absorbency of Paper Towels."

The results of the experiment were that the Sparkle brand paper towels were the most absorbent. It absorbed on average, 50ml of water, when the Bounty brand paper towels absorbed only 44.75ml of water. Fundamental essentials best sponges we tested rated, so as: Bounty Select-A-Size 2-Ply. Brawny Pick-A-Size 2-Ply.

12 Abstract The purpose of our project was to find out which paper towel was the strongest. We were curious. We thought that Brawny would be the strongest. We used pennies and water to test the strength of each paper towel. Brawny was the strongest. Publix was the weakest. Our hypothesis was correct because Brawny won.

September 1st, 2015 /. Kathryn King /. News. This year Brandon Barth's Earth science classes have been learning about the scientific method. To do so, they have been doing multiple mini experiments. They will be testing the absorbency and strength of 3 different paper towel brands: Scott, Kirkland, and Great Value.

The Bounty paper towel was the strongest. Zoë Miller After being soaked, the Bounty towel held an impressive 43 ounces or 2.69 pounds. Bounty was the most absorbent and the strongest paper towel ...

To determine which paper towel brand is the strongest, we conducted a series of tests to evaluate each brand's strength. Our testing methodology involved assessing each brand's tensile strength, absorbency, and durability. We tested each brand by measuring the length and width of each paper towel and calculating its weight per sheet.

Procedures: Step 1: Tear off 2 differnt paper towels brands. Step 2: Get a cup or bowl of water. Step 3: Then get the first paper towel brand and then pour water in it. See if it tears off. And then get the other paper towel and do the same. Which ever doesnt tear off first is the strongest.
