Abstract
Differential classification and categorization are core activities in all disciplines. Although the methods used to collect and identify information vary widely, the fundamental sameness of or difference between many types of samples is a common objective. We have developed this idea in a set of activities we call "Who Has the Same Substance that I Have?", which not only serves as a design for chemistry laboratory tasks, but also as a generic blueprint for any discipline. In our first-term chemistry laboratory course, students learn about chromatographic, spectroscopic, and chemical techniques as tools for collecting information. They work collaboratively to answer the "Who Has the Same Substance that I Have?" question for groups of powdered white solids and again for clear colorless liquids. A number of others have adapted this idea to their own context.
