A Case of Respiratory Distress 

This clinical case study was developed to engage students by making connections between core concepts in chemistry and physiological processes in the body. The case pertains to medication-induced methemoglobinemia, its etiology, diagnosis, and treatments. Concepts taught by the case include the use of conversion factors, pH, buffering, Le Chatelier's principle, blood chemistry, and respiratory and metabolic acidosis and alkalosis. The case is suitable for use in a General, Organic, and Biological (GOB) Chemistry course or other introductory general chemistry course as well as undergraduate physiology courses. The case also could be adapted for use in undergraduate pharmacology and medicinal chemistry courses.


A Light Lunch?: A Case in Calorie Counting

This case study was developed to engage students by making connections between core concepts in chemistry and obesity related factors. The case is in the form of a story between two friends and their underestimation of the calories they consumed in a meal and their overestimation of the efforts needed to maintain a healthy body weight. Concepts taught by the case include use of conversion factors, calculation of percentages and body mass index, and calculations of caloric values of different foods. The case is suitable for use in courses in general, organic, and biological chemistry as well as in undergraduate nutrition courses.
