Topics such as sports, exercise, health, and nutrition can make the science of physiology relevant and engaging for students. In addition, many lessons on these topics, such as those on the cardiovascular, respiratory, and digestive systems, align with national and state life science education standards. Physiology Understanding Week (PhUn Week)—sponsored by the American Physiological Society (APS)—is an annual outreach event in November that highlights the science of exercise and health. As part of this event, physiologists volunteer to collaborate with teachers in their local communities and visit classrooms to engage students in physiology-based activities.
