Changing Body Positions: How Does the Circulatory System Adjust?

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing, and lying. Learners are also challenged to think about how the circulatory system might behave in a microgravity environment (i.e. astronauts in space). The lesson guide, part of NASA's "The Brain in Space: A Teacher's Guide with Activities for Neuroscience," includes background information, evaluation strategies, and handouts. Note: cost of materials does not include cost of stethoscope or sphygmomanometer; these may be borrowed from a nurse.
