A new introductory lab course drawing on theories of inquiry-based learning has been designed for Haverford's advanced general chemistry section. The goal is to teach chemistry students how to think like scientists rather than simply follow the recipe-like instructions common to student lab manuals. Students synthesize and purify a “mystery molecule” and spend the semester working in groups and attempting to identify and characterize the compound and its precursors. After the initial synthesis, students direct the course, deciding what experiments to perform to help identify their unknowns. This course prepares students for research better than traditional laboratory programs while still providing them with the skills necessary for advanced lab courses.
