The heart is one muscle that never seems to get tired, despite all the hard work it does, all day and all night. In this episode of the popular series, Bill Nye the Science Guy: Heart looks at this organ, no bigger than a fist, that moves blood throughout the body. Nye, a former standup comedian, takes a subject that might bore many students, and instills his own brand of excitement and energy. His programs mix many elements, including humor and music, and a rapid-fire pace. Nye has the ability to communicate on a level that kids can readily understand.
