Students experiment to rank the wet strength and absorbency of four brands of paper towels. Based on their findings and the cost of each brand, they determine which brand is the "best buy." These activities provide a stimulating introduction to consumer science and the concept of controlled experimentation. Students can go on to devise their own experiments, tests for other consumer items, or advertisements for paper towels based on their test results.
