This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist. Students are told that two bodies have recently been recovered from two different lakes. Due to a mix-up at the morgue, the coroner's office is unable to determine which body came from which lake. The students' task is to develop a methodology to solve this mystery as well as determine whether the deaths were the result of murder or mishap. The case could also be used in instrumental analysis courses or adapted for a non-majors course in the general education curriculum.

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.

Playfully alluding to Lewis Carroll's tale of Alice Through the Looking Glass, this case study considers the problems that would arise if a person were to cross over into a mirror-image environment. Students read about a drowsy undergraduate studying for a stereochemistry exam who finds herself in a place where spearmint gum tastes like caraway seed. The case emphasizes the lock-and-key theory of enzyme action and stresses the need for molecules to have the proper chirality if they are to be biologically useful. Designed for introductory organic chemistry and biochemistry courses, the case could also be used in biology courses.

This "clicker case" follows Susan, an intern at a local hospital, who has admitted a patient she discovers has used the drug Ecstasy. The girl becomes delirious, and Susan begins to suspect that she may be suffering from water intoxication. The case is designed for an introductory biology course for either science or non-science majors, though it could be adapted for upper level courses. It uses an example of water intoxication to introduce membrane structure and function, osmosis, and electrolyte balance in the body. The case itself is a PowerPoint presentation (~800KB) shown in class that is punctuated by multiple-choice questions students answer using clickers. It could be adapted for use without these technologies.

In this decision case, a congressional staffer must weigh a number of competing concerns and issues, including popular reactions to genetically modified organisms, in deciding how to present information to her boss, an influential congressman drafting legislation to support agricultural research. The case explores the social and biological issues surrounding micronutrient malnutrition, including deficiencies of several vitamins and essential minerals, especially iron, iodine, and vitamin A, which affect at least one-third of the world's population, primarily in developing nations. Developed for a graduate-level seminar on "Genomics, Agriculture, Food Systems and Development," the case teaches about the issues surrounding genomic applications in agriculture and their implications to health, environmental stewardship, economic sustainability, and national development.

Intelligent Design continues to be a hot political and educational topic in some parts of the country. This discussion case study uses the dramatic setting of a public school board as it considers whether district science teachers should be made to read a statement to their classes identifying Intelligent Design as a competing theory to evolution that is worthy of scientific consideration. The relevant statement is in fact the one that was at the center of the 2004 controversy in Dover, Pennsylvania. This case would be appropriate in general biology or advanced courses where the focus is on evolution.

This case is a "clicker" adaptation of a similarly titled case by Merle Heidemann and Gerald Urquhart of Michigan State University, "A Can of Bull?" The story introduces students to basic principles of metabolism and energy through a biochemical analysis of commonly available "energy drinks" that many students purchase at relatively high prices. Students learn to define energy in a biological/nutritional context, identify valid biochemical sources of energy, discuss how foods are metabolized to generate ATP, and critically evaluate marketing claims for various energy drinks. The case can be used in introductory level courses to introduce these principles or as a review of basic biochemistry and nutrition for upper-level students in nutrition, physiology, or biochemistry courses. The case is presented in class using a PowerPoint (~2.3MB) that is punctuated by multiple-choice questions students answer using personal response systems, or "clickers."

The discovery of the platypus had the scientific world in an uproar and kept it tantalized for decades. Here was the strangest animal ever seen. How was one to classify it? It had fur. So, was it a mammal? But then what to make of its duck-like bill? And how did it produce and suckle its young? Based on the book by Ann Moyal titled Platypus: The Extraordinary Story of How a Curious Creature Baffled the World, the case focuses on classification and evolution and models the scientific process, with scientists arguing, debating, collecting more information, and revising their opinions as more data become available.
