Is Bounty the "quicker picker-upper?" Are expensive shampoos better? Are all antacids the same? The authors' fourth-grade students posed and answered these questions and many more during their recent "Consumer Product Testing" unit in which they designed experiments to assess these products' qualities and learned to question the advertising that is so much a part of their lives. The unit was a terrific success--students were thoroughly engaged in the learning, and consumer science was a perfect way for students to learn about scientific inquiry and explore the properties of various materials while making important social studies connections. The author packed a great deal of learning into a few science periods and effectively met numerous learning standards. This unit is briefly described in this article.
