Paper Towel Absorbency Experiment

The problem that I am trying to solve during my project is which sponge will absorb water.The purpose (related to the problem )of my investigation is to know how much water can be absorbed by certain brands.What I am going to be doing is getting different brands of sponges to use.How I will do this is I will measure the water in the bowl in ml and measure how much is left in the measuring cup and then record the data.The reason I am doing this is because, like everyone, I spill things.Also it would be important to know how to clean it up fast in stead going back and forth a lot. For someone else they could use it like me or if they had a leak and they didn't want it to go everywhere.Also if you want to save water some people wash there dishes

The purpose of this experiment was to test multiple brands of popcorn under the same setting in order to conclude which one statistically popped the most kernels. I tested the butter flavor of Orville Redenbacher, Wal-mart’s Great Value brand, and Pop Weavers. The different bags of popcorn were popped in the same microwave for the same amount of time, 3 minutes and 15 seconds. Then, the popped corn was counted, as well as the un-popped kernels, in order to determine a ratio, and then I recorded the results in the data table. I repeated these steps two more times for a total of 3 trails for each brand. Then I compared the ratios of all the bags to determine which brand yielded the most popped corn. The statistical technique used to evaluate the data was to find a ratio between the number of kernels in the bottom of the bowl and the number of popped kernels. To find this, I divided the number of the actual popped corns by the total number of kernels left in the bottom of the bowl. The ratios and percent were then compared. Once all my results were in the data table, I averaged the 3 trials for each brand of popcorn.

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.

This experiment has a goal of testing a household cleaning theory that dark sodas such as Coca Cola or Pepsi can be used as a cleaning agent and cut through dirt and grease effectively as a cleaner.  For the experiment, the researcher/writer has purchased Pepsi products, Pepsi specifically to use as the cleaning product to test.  The researcher/writer will clean six different types of messes (Food stains of ketchup and mustard on a shirt, kitchen counter grime/grease, bathroom counter soap scum, car windshield and battery corrosion on a car battery and bathroom counter/sink).  Each item will be cleaned with Pepsi and soap and water, with the soap

8. When finished recording your numbers from the two trail experiments take the average of each trial and compare the final results.

I believe the most appropriate and thorough way to collect the data for this experiment was in the way described in the collection of data. I cooked to each brand according to the directions provided by the manufacturer. By following their directions, that would ensure maximum amount of product.

The purpose of this experiment was to investigate the effect that different liquids would have on gummy bears. To do this we brought in different liquids, such as Fanta soda, salt water, water, and baking soda water. My hypothesis is, If you put gummy bears in different liquids then they might dissolve or enlarge. This experiment was tested on 9-14-17 and my group and I started gathering data, we started with 1 minute, 5 minutes, and then 24 hours. There wasn’t much change in the 1 and 5 minutes, the real change happened overnight. The next day of this experiment the gummy bears had mostly enlarged and softened, there was one that accomplished to do the exact opposite, the salt water gummy bear decreased and hardened. I believe that the salt

The results indicate that my hypothesis was correct. I performed this test because I wanted to know if Viva was more absorbent that the local store brand to determine if the extra cost was worth it. My findings will help other consumers make a decision based on absorbency as to which paper towel to purchase.

Continue adding quarters within five second intervals to the paper towel no longer supports it

* Place paper towel over clear glass bowl with rubber band holding it in place.

Question: Will changing the water temperature affect how quickly a gummi bear dissolves in water? Hypothesis: If the temperature of the water is warmer, then the gummi bear will decrease more quickly in size than compared to cooler temperatures. Materials: Gather the following materials including: •safety equipment including: goggles, gloves, and apron •two 25 mL beakers •one graduated cylinder •one thermometer •one hot plate •8 red gummi bears from the same brand •20 mL of normal tap water in each beaker •one balance measured in grams •forceps •paper towels Procedure: 1.Gather all the materials listed above. 2.Include data tables in your experiment by doing two trials.

The hypothesis stated that the warmer water would have more of an effect than compared to the colder water. This is tested when the data is found for how much change occurred over the 3 trials. What the experiment was trying to find out is would water temperature have an effect on a nylon mesh when put under stress. The experiment did that when the lacrosse ball applied the stress to the nylon mesh after being exposed to the temperature of water. This is how the hypothesis was tested during this

The purpose of this experiment will be to determine which one of the leading brand paper towels, Bounty, Brawny, or VIVA, will absorb the maximum amount of water and which brand is consider the sturdiest of these towels. First trail will be the absorbency test to see how much liquid each towel will absorb. Then a strength trail will be performed to see how much weight each towel will be able to hold while wet.

The results of this experiment support the rejection of the null hypothesis and predict there is a difference between Superflab, uncooked rice, green Play-Doh, and orange Play-Dough when providing the

Problem: How do different material cups such as, plastic, paper, and styrofoam cups affect an anemometers speed?
