A different idea on a group activity for kids when learning or reviewing the scientific method. They choose a magazine ad for a home product such as a cleanser, and proceed to develop an experiment that would prove or disprove it's claims. You can have the students actually do the experiment, or simply design it using the steps to the scientific method. I have done this before with household products and the kids love it. It would work for any science class. A student sample is included.
