Two of the most frustrating things for me as a teacher are the way units and jargon can get in the way of understanding concepts. When I teach pre-nursing and medical students about blood pressure, they end up memorizing a lot of information that would be obvious if they had remembered some of their basic physics—particularly the ability to change units. Of course, the other solution would be to use units that make sense to the students. Some non-majors taking physics classes are thinking about careers in the medical field, but often don't see the connection between physics and their interest in medicine. However, there are a number of ways instructors can build on students' interests to help them explore real-world applications of physics and medicine. This laboratory exercise provides an example of one such connection, by engaging students in considering why large g-forces may cause individuals to “black out.” We have used this activity with success in a pre-nursing physiology class and believe it could be easily adapted for teachers of high school physics.
