The next day Professor Peabody brought two different brands of paper towels to the lab. He wanted to compare these two with the roll he had in his lab. He tore off one sheet from each roll and compared them.
- Your teacher has three different brands of paper towels. Look carefully at each brand of paper towel. Compare the three brands.
- How are they alike? How are they different?
- Which do you think will pick up the most water? Show or tell how you decided.
Professor Peabody investigated further by dropping 5 drops of water on a sheet of each brand of paper towel.
- Will the spots be the same size?
- How can he measure the size of the spots?
- Which variable will give the best measure of the size: length, width, or area?
Professor Peabody used the TIMS Laboratory Method to find which paper towel picks up the most water. You will do a similar experiment.
Use The Better “Picker Upper” Lab pages in the Student Activity Book to compare different brands of paper towels to determine which picks up the most water.
