Lynn Poole invites members of the Federal Communications Committee, meeting in Washington, DC for hearings on the use of television as an educational medium, to watch this program as a practical example of how educational institutions can bring educational programs to the American people. This is the first public showing and demonstration of a combination of x-ray photography and fluoroscopy picked up by a television receiving tube, affording both dynamic and clear internal views of patients. The equipment was constructed at The Johns Hopkins University with funds from the U.S. Public Health Service and developed by Dr. Russell H. Morgan. Dr. Morgan shows and explains the dim images of a standard fluoroscope and the static x-rays of a chest, colon, and kidney produced on a radiographic table to compare the strengths and weaknesses of each procedure. With physicist Ralph Sterm at the controls and assisted by Vernon Bowers, Ed Custer, and Roy Collier, Dr. Morgan then demonstrates his new invention, which amplifies images 300-3,000 times, and x-rays the movement of the chest and hand of Joan Hunter for viewers to see. Finally, in the first live television, inter-city diagnosis, Dr. Paul C. Hodges, at the University of Chicago, and Dr. Waldron Sennott, at the U.S. Marine Hospital in New York, observe the x-ray/fluoroscopy images broadcast on their televisions and consult with Dr. David Gould, at Johns Hopkins in Baltimore, and together diagnose and prescribe treatment for a patient, machine operator James Carter, who has metal particles clearly lodged in his chest and possibly his lungs.

The program begins with a tour of the Children's Hospital School of Baltimore, Maryland. Dr. Raymond Lenhard describes the symptoms of poliomyelitis, or infantile paralysis, and treatment of the disease. In the exercise room, a physical therapist demonstrates the muscle test for fingers and shoulders and how patients progress from simple to complex exercises. Patients are shown in crutches and leg braces, in the rocking bed, and in the treatment pool doing underwater exercises. "Iron lung" respirators are demonstrated and explained. Lynn Poole interviews two patients who recovered from polio, and he alludes to research being done in polio immunization.

Volcanoes are found in certain areas of the earth that are also susceptible to earthquakes. Pressure beneath the crust of the earth forces lava and hot rocks up through the crater of volcanoes. Various types of lava and volcanic rocks are discussed.

Research in human engineering affects many operations of everyday life. Experimentation with sizes and shapes of numbers, knobs, and traffic signs can make driving safer and machines easier to operate. The first eight or nine minutes are missing from the videorecording of this program.

This program describes the atom as the smallest structure in the universe and how they combine to form molecules. Molecules combine together to create larger structures that can react and combine with each other.
