the world. Do your students really know what aspirin does? What
it's made of? How common brands differ? Your class will answer
these and other questions as they perform a variety of tests on
several brands of aspirin. In the process, they'll determine each
brand's chemical effectiveness and composition for each brand as
well as the cost-benefit relationships between these attributes.
