In this “clicker case,” a three-year-old girl gets into the medicine cabinet and ingests an unknown number of aspirin tablets. Her brother calls 911 and the girl is taken to a nearby hospital, where she is treated. The case is used to discuss the Law of Mass Action, chemical equilibrium and equilibrium constants, pH, and weak acids and buffers in the context of medical management of a life-threatening emergency. It is called a “clicker” case because it is designed to be presented in a class that uses personal response systems, or “clickers.” The case is presented via a series of PowerPoint slides (~400KB) punctuated by multiple-choice questions, which the students answer using their clickers. It could be adapted for use without these technologies. The case is suitable for use in an introductory biology course where integration with biologically relevant chemistry is an important course objective. It could also be used in a chemistry course.
