Science Test- Paper Towels
“Which kitchen paper is the best at absorbing liquid?”

Scientific Principles- Since paper towels are used to pick up liquids, the volume of liquid it can hold is important. The amount of liquid a towel can absorb can be measured by the volume of liquid it picks up.

Aim- To investigate which kitchen paper is the best at absorbing most liquid.

Hypothesis- I think that Viva/Kleenex will be the best at absorbing most of the liquid because I think it’s the thickest paper towel and I think that it can hold a fair amount of liquid that it requires.

Equipment- • Different types of paper towels- To test out which paper towel absorbs most liquids in the experiment. 1. Home Brand Coles 2. Viva/Kleenex 3. Handee Ultra • Different types of liquids- To use to test the paper towels with. 1. Orange Sunkist 2. Coke 3. Schweppes Raspberry • Stopwatch – To time the 30 seconds • Tape measurer or ruler – To measure the amount of liquid that has been absorbed onto the kitchen paper. • Sticky Tape – To tape the paper towels to A4 Paper after they have been used in the experiment. • 3 cups – To pour the liquids into. • A4 Paper - To put the kitchen paper towels onto. • Pen - To label the 3 cm and to gather results. • Camera – To take a photo of the paper towels.

Risk Assessment Table-

|Item |Risk |Justification |
|A4 Paper |First Aid Needed (6) |Paper Cut |
|Cup(s) |First Aid Needed (4) |Could cut yourself if some sharp edges |
| | |appear or either if the cup smashes. |

Procedure- 1. Grab 3 cups that are the exact same length, width and is the exact same size. 2. Pour into the 1st cup

In this experiment, there was one specific error, which was not holding the cup rim directly onto the middle of the paper. Instead, the paper was soaked by the water. This affected the results, because the tests weren’t done exactly the same, so therefore the results couldn’t be comparable. I can reduce this error, by making sure that the paper was directly onto the cup’s rim, without the water touching the paper…

Two future questions are; “Which shape of sponge is best for soaking up water?” and “Which oil is the hardest to clean using a sponge?”. Scientists would want to know if the amount of layers in a sponge affect the amount of oil soaked-up, and if a porous layer soaks up more oil than a non-porous sponge. These could be tested in almost the same way as the experiment…

In the investigation 1.2, we tested 3 demonstrations. And in the second demonstration In demonstration 2 the cup was put into the water, upside down, the beaker overflowed, and the paper towel that was inside of if did not get wet because the air was already taking up the space in the cup, therefore the water couldn't go inside the same space. In demonstration 1 the cup was placed in the water right side…

There are many different brands of paper towels available to consumers, all of which claim to be the most absorbent. How do we determine which paper towel is the most absorbent? The absorbency of a paper towel can be measured by the volume of liquid it can absorb. We are going to conduct an experiment that test the absorbency of two brands, one national brand Viva and a store brand Kroger by measuring the amount of water that each can absorb. We will answer the question: Which paper towel is more absorbent Viva or Kroger Value (store brand)?…

Blood is mostly water, therefore the physical properties of water, its cohesion, adhesion, and high surface tension, affect the patterns blood makes when it spatters. This lab activity reinforces some of these important physical properties. It could be conducted as a deductive activity in which students are asked to explain the results of the various experiments in terms of water’s physical properties. It could follow, for example, a lab activity where students compare the properties (drop size, evaporation rate) of three different liquids and then precede, for example, a discussion of the differences in composition and physical properties between blood and water.…

This investigation was chosen to serve as a guide for people to know how one recycles paper. One of the things we use most often— especially in school — is paper. It takes about 20, 000 trees to make the Saturday edition of a big city newspaper. Therefore we use unimaginable amounts of paper a day. This study can help us to reduce, reuse, and recycle (ecokids.ca/pub/fun_n_games/printables/activities/assets/science_nature/paper_making.pdf)…
