Students will use previous knowledge in the three key systems (Digestive, Respiratory, Circulatory) and background in additional systems (Nervous, Skeletal, Immune) to diagnose patients based on the case studies presented here. In groups of 3-5, one student will play a 'patient' and present a case of some illness and patient background. Another student, acting as the primary physician will diagnose him/her based on the information provided. The other student(s) will provide support, and along with their notes, the primary physician will present the case to the attending (teacher). Students will be graded on their presentation as a patient but primarily on their diagnosis using their classmates and notes as resources. Students will rotate roles until all group members have had a chance at both roles. Solutions are provided in faint font in the charts. Teachers are encouraged to print off and cut out the case studies for students to hold, while they're in character. Laminating the cards will make them useful for multiple years.
