Understanding Life is the educational website of The Physiological Society, providing "support for the teaching and learning of physiology." A good place to start is the What is Physiology? area, which offers an overview of this field of human inquiry. The Resources area is a well-designed archive of instructional materials that include "The story of a single heartbeat," "The Science of Life," and "Planning an experiment." It's worth noting that visitors can create their own accounts on the site so they can receive specialized newsletters, tailored website content, and become eligible to enter scientific competitions. Moving along, the Events area lists important goings-on that will be of interest to educators and those involved with science pedagogy. [KMG]
