If you used a largely quilted, soft paper towel, you may have noticed that it absorbed more than others. Water wants to be wherever it can be held and kept together through cohesion and adhesion. In this case, the puffier, softer paper towels were able to hold more water because their capillarity was greater. This is due to their larger holes and pockets, which can hold more water than standard paper towels.
Ever notice how rough and flat the brown paper towels in your school restrooms are? Paper towels are a great way to explore capillary action because they show the ways in which water and other liquids can move upwards through a material at different rates and quantities.
Feel free to keep investigating! Have any celery in the refrigerator? Celery can also be a great example of capillary action. Mix water and food coloring in a cup. Submerge a freshly cut end of a stalk of celery and watch the color be pulled up through the stalk! I have read and agree to Education.

Third Grade Science Projects. Brawny was the runner up, not far from Bounty. It was the thickest of all towels. It was most absorbent, we think because of its how thick the towel is. Essentials Everyday came in third. It wasn't bad or good. It preformed exceptionally well on all tests. Shoppers value was the worst. It did not preform well in any test except for the oil test. We think this because it is a very thin towel, made out of cheap materials.
Conclusion The outcome of the experiment was that Bounty preformed the best and Shoppers Value preformed the worst. The purpose was to find the best towel that was both absorbent and strong. Our hypothesis was Bounty will do the best in both tests, it will absorband clean the best, and will be the strongest paper towel. Brawny will do exceptionally well at all tests, and will have even scoring. Essentials Everyday and Shoppers Value will both be the worst, and not do well in any test.
Our hypothesis was almost spot on. The only thing is that Brawny was a close runner up, and Essentials everyday did exceptionally well. What we found interesting was the Shoppers value did pretty in absorbing the oil. It was also weird that Bounty didn't do very well in absorbing the maple syrup. Some sources of error, could've been that our measuring was off, our surface wasn't clean enough, we didn't shake our towel enough or too much for the strength test.
The point is if you would like a towel to do the job you want get Bounty! If you would like to save money and do an exceptional job get Essentials Everyday. More presentations by Linda Owl Cell Project. Blog 31 August Prezi at Dreamforce Add five teaspoons of water to the paper towel, and then start placing coins on top of it, one at a time.
Place all of the water in the center of the towel. Add quarters to the paper towel until it breaks. Record the number of coins on your data sheet. Once you have done this with all of the paper towels, you can rank them from strongest to weakest. Add quarters one at a time. Your hypothesis can be an educated guess based on personal experience or advertising. 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 the number of quarters each brand handled.
Your chart will work well here.
Testing the Strength of Paper Towels. 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.
The Paper Towel Experiment is a project about which type of paper can absorb more water.
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. Aug 24, · In this paper towel science project, we will be testing which type of paper towel contains the highest rate of capillarity (or ability to absorb water into its many small spaces). Download Project Add to Collection/5().
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. Although the options are limited, we have provided you the best experiments that you can do with paper towels. 5 Science Experiments with Paper Towels. 1) Stretch Test – Viva® Vantage Paper Towels pride themselves on having a great stretch that’s responsible for the strength. Practice measuring with your kids and test out the stretch for yourself. You’ll need a ruler and one paper towel. Place the paper towel on a flat surface.
