Either dispose of paper towel in a waste bin OR place in pie pan and throw them all away at once when you finish 8. Record the volume of water remaining in the cylinder and subtract from the original 30ml to see how much water the towel absorbed 9. Repeat steps two more times with the same brand of paper towel.
Now take the next brand of paper towel and do steps 3 — 9. Data Table Record your data as you do the experiment. Graph Draw a bar graph of the average of the tests for each brand of paper towel. It will look something like this: The independent variable in this experiment is the brand of paper towel i. Conclusion Now that you have the data, and the graph, students can reach a conclusion.
And your children can see a practical use for science! The following two tabs change content below. Bio Latest Posts. Meryl homeschooled her 4 children and during that time started teaching at the local homeschool co-op.
She still teaches there - as well as online at FundaFunda Academy. In her spare time she loves reading and traveling. Each paper towel effectively absorbed water and was able to hold a bit of weight while damp but some certainly performed better than others. Coming out as the most absorbent and the strongest towel, Bounty's paper towels were the most impressive of the bunch. World globe An icon of the world globe, indicating different international options.

Bounty was the strongest and most absorbent paper towel we tried. Sign up for Sidekick to get the best recs for smarter living. Loading Something is loading. Email address. Water is attracted to cellulose and likes to be soaked up and stick to the cellulose in paper. When you looked through your microscope, did you also see the spaces between the fibers? These empty spaces affect the absorbency of the paper: Water likes to stick together and fill these spaces as it follows the water attracted to the cellulose.
More spaces allow more water to be absorbed. But what would happen if you add a tiny space between sheets of paper towels? Would the empty space between the sheets help to hold more water? Observations and results Did you measure a higher mass for the folded wet paper towel and did your hands feel drier when you used it? This is expected, as the tiny space between paper towel layers helps hold more water. Paper is made of cellulose, which water molecules like to cling to.
As a result, paper readily absorbs water. Paper towels are especially absorbent because their cellulose fibers have empty spaces—tiny air bubbles—between them. Water molecules, which like to stay together, follow the one another as they are absorbed by the cellulose and fill the empty spaces. Layering the paper towel creates more spaces for water to fill, which explains why your layered paper towel could hold more water and was more efficient at drying your hands.
The next time you reach for the paper towels, remember to fold! You might feel good knowing you just saved an extra paper towel from being used.

Bounty Essentials 2-Ply. That makes each sheet only 0. In our tests Bounty was the best at scrubbing compared with Viva , and sometimes much better.
On average, it could take Paper towels , napkins, tissues , and toilet paper are all paper products and are, therefore, made out of paper. But, although they are all made from paper , kitchen paper towels are more absorbent than toilet paper , napkins or facial tissues in picking up and absorbing large amounts of liquid.
The single-ply products — Viva and Scott — were the most expensive in terms of cost per ounce of liquid absorption. Two main chemicals found in most paper towels are Chlorine and Formaldehyde. Chlorine is quite commonly used to make the paper towel white in colour.
Also, just like thermal receipt paper , Paper Towel has been found to contain very high amounts of Bisphenol A BPA , even paper towel made from recycled paper. Place marbles one at a time on the wet area in the middle of the paper towel. Count how many marbles the paper towel holds until it breaks. Record the number of marbles each brand holds before testing another brand. Thicker, heavier towels are usually more absorbent than thinner, lighter towels, but take longer to dry, of course.
Towels made of Egyptian or Pima cotton , premium cotton brands, are super absorbent, and towels made with rayon absorb even a bit more water than cotton. The more the layers, the better the paper towel will absorb.
