This case examines the integrated physiological response to dehydration and starvation from the real-life report of a girl discovered 15 days after an earthquake devastated Port Au-Prince, Haiti, in January 2010. From the meager scientifically relevant facts reported by the newspaper accounts of the girl's condition, students are asked to work through the pathways of water loss from dehydration as they examine the multiple systems involved in homeostatic responses, and then are asked to calculate whether it is possible for a human to withstand 15 days without water. The case also gives the instructor the opportunity to differentiate between the general adaptive response to a stressor and the specialized adaptive responses exhibited by well-acclimated natives. The case was designed for an upper division comparative or human physiology course or possibly a graduate level medical physiology course.

In the weeks following the September 11, 2001, terrorist attacks on the World Trade Center and the Pentagon, anthrax-laced envelopes were mailed to individuals in government and the news media. Thousands were treated for exposure, and five people were killed. At the same time, scientists solved the last remaining pieces of the anthrax puzzle and the mechanism of infection of the anthrax toxin is now well understood. Developed for a second-semester biochemistry course, this case presents students with a wealth of biochemical, microbiological, and immunological material to analyze. It also explores important societal issues related to national preparedness against bioterrorist attacks, funding for biodefense research, and the use and misuse of antibiotic therapy.

Frank and Joe are 24-year-old fraternal twins who share similar interests, including cycling. The brothers decide to attempt their first long-distance bicycling trip, retracing the journey of early American explorers Lewis and Clark to the Northwest. Along the way, serious problems arise. Students review normal physiology of organ systems as well as changes that occur during physical exertion to piece together an understanding of the medical condition of one of the cyclists. The pivotal point in the case is learning that seemingly harmless and legally available substances can lead to potentially fatal outcomes, affecting organ systems already taxed beyond normal limits. This case is designed for use in a human biology course after students have learned about the integumentary, respiratory, cardiovascular, neuromuscular, and urinary systems.

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.
