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.
