The results of the experiment for the test of absorbency were that the Sparkle brand proved to be the most absorbent. The single-ply products — Viva and Scott — were the most expensive in terms of cost per ounce of liquid absorption. It even works well as an alternative to napkins and tissues. But how does this language translate to real-world performance? Using this sheets-per-ounce data, we were able to calculate the cost per ounce of liquid absorption for each paper towel. Perhaps you could to rate the strength and softness, or try and calculate how much each towel costs per sheet. This eliminates waste and helps you save money by ensuring your rolls last longer.
Supposing your child has a few days to complete the project, a seed germination experiment is relatively hassle-free, and usually goes over well with teachers and students alike. Bean Plant Projects A simple way to make a science fair project with paper towels involves lining a foam cup with a wet paper towel and slipping a lima bean or other fast-growing seed between the towel and the cup. To test a paper towel for strength, stretch it over the mouth of a very wide jar and use a rubber band to secure it. Your chart will work well here. Results The results of the experiment for the test of strength were that the Sparkle brand proved to be the strongest. These paper towels form the subject matter of a number of science projects owing to their physical properties that prove useful in forming a hypothesis. The paper towel was held it in place with a standard rubber band that was wrapped around the top of the beaker one time.
Place the paper towel on a flat surface. We found to be a strong runner up. You also need to collect impure water from a pond, or a puddle, or contaminate it purposely with impurities. How we tested With our top six finalists selected, we developed a series of tests to compare them. Before we could get the egg, the chickens knocked it off of the ramp. Then slowly add pennies to the part of the paper towel stretched over the mouth of the cup.
Qualitative analysis The experience of using a paper towel involves much more than just measurable data. We read blogs, like Lifehacker, to find out what people look for in their paper towels. Again, Brawny and Bounty distanced themselves from the competition, withstanding 13 and 12 swipes, respectively. Bounty also tied Brawny in the volume absorbency test, needing just two and a half sheets to pick up two ounces of water. In the project I learned bounty is the best paper towel brand. However, the recycled material clearly impacts the effectiveness of the White Cloud sheet. The bottom line We feel confident recommending both Brawny Pick-A-Size and Bounty Select-A-Size paper towel products, but we believe Brawny is slightly better for use all around the house at a better value.
We tested six of the top paper towel brands for strength, durability, absorbency and overall usability, and Brawny was the best performer overall. The weights that we used were 27 g each. Handle carefully to avoid tearing. In every store, big or small, there are numerous brands of paper towels available, each claiming to be the best, the most absorbent or the cheapest. Note how many pennies it takes to break through the paper towel. It is important to start planning your project early, as you will need time to complete each step of the project, and you cannot usually do this the night before the due date.
Volume: Our second test determined how many sheets each brand needed to completely absorb two ounces of water by volume. While experimenting I first got a paper towel and soaked it in water. Between each layer, insert a different filtration material to be tested, such as a layer of cotton balls, some pieces of newspaper, a handful of thinly-spread gravel, a handful of sand, and anything else you think might filter the water. In fact, all three picked up the wine relatively quickly and easily without having to exert much pressure. From humble beginnings, paper kitchen towels have become a billion dollar industry. It also shredded quickly in our home tests, like scrubbing floors and swiping over sandpaper.
Project description: In this science project you will perform experiments to compare different paper towels for their strength. It took several napkins to clean the egg off of the wood and then we still had to spray the area with water. Of our top six, only Scott Choose-a-Sheet and Viva were one ply. Then dip a paper towel into the beaker and gently remove it, perhaps using tweezers so that you minimize squeezing the water out. The other four brands were substantially weaker, all breaking under the weight of 104-116 pennies or 9. A stronger paper towel has more uses and will last longer.
Place as many pennies on the wet paper towel until it starts tears 3. Stretch the paper towel out. We try to use cloth as much as possible in our house. Brawny feels cloth-like, which helps when washing floors and cleaning windows. I also know that Bounty is good at absorbing an abundance of water.
Fill three fourth of each plate with water. In our tests around the house, Viva — which uses a mix of paper from responsibly managed sources — was a much closer rival to Bounty and Brawny than the other products. We used a graduated cylinder which was filled with 100 mL of water. You can declare whichever brand absorbs the most water as the most absorbent! The average amount of pennies a paper towel can hold is about 200 pennies. They are made up of disposable papers, capable of absorbing water, dirt, grime, oil and stains.
