A view of life on a typical Kansas wheat farm. Shows how members of an average farm family spend their time, how the land is cared for, and how the winter wheat is planted, harvested, and stored in bins and elevators. Emphasizes the threat of inclement weather on wheat harvests. Includes animated sequences.
Reveals the appearance, tonal qualities, and functions of various instruments of the woodwind choir--piccolos, flutes, clarinets, oboes, English horns, bassoons, and contrabassoons. Uses close-up photography to illustrate the techniques of playing these woodwinds. Includes excerpts from Brahms' First symphony, Beethoven's Turkish march, and Brahms' Fourth symphony.
Reveals how the nature, concentration, and temperature of reacting substances affect the velocity of chemical reactions. Through laboratory experiments and animated drawings demonstrates and explains the role of these factors with respect to the velocity of molecules, spheres of influence; and vibrational energy. Through animation explains reversible reactions and the abstract processes of chemical equilibrium.
Black and white footage of homes and buildings that have been damaged and destroyed, possibly as the result of a tornado. Ends with a man scaling a catfish. Location unknown.
Bernadine Bailey's sister, Joy, and her nephew, Paul Freeman Wilkinson emerge from the Wilkinson family home in Western Springs, Illinois. Paul is wearing roller skates. He roller skates down the sidewalk with an unknown girl as a collie plays alongside them. Bailey joins her sister, nephew, mother (Nellie Voigt Freeman), and an unknown man (possibly her husband, John Hays Bailey) as the group poses in front of the house. Brief shots of Paul Freeman Wilkinson riding a tricycle and a couple (possibly the Wilkinsons) working in the yard.
Shows a group of people posing for the camera in front of their house, including Nellie Freeman, Bernadine Bailey's mother. The rest of the group is likely Paul R. Wilkinson (the younger man with glasses), his siblings, and parents. Paul F. Wilkinson, Bernadine Bailey's nephew, is playing with a group of other children.

Summary:
Presents study of economic and social conditions in a society isolated from the rest of the world by almost impenetrable natural barriers. Discloses representative aspects of the daily life of superstitions. Analyze the factors involved in continued existence of backward societies.
Shows how domesticated animals are used throughout the world for power, clothing, materials, and food. Shows how about 50 of the 500,000 known species of animals have been domesticated. Junior and senior high school level. An instructional sound film.
Demonstrates through animated drawings and cinemicrography the three lines of defense against infection--the skin and mucous membranes, the lymphatic system, and the circulatory system including liver and spleen. Explains immunity to certain diseases, and describes how man can improve defenses against infection.
Through animated drawings and photography explains the hypothesis that electricity consists of unit elementary charges. Demonstrates the conduction of electricity through solutions, gases, and vacuum: Faraday's laws; movement of charges in vacuum tubes: operation of photoelectric cells: and reproduction of sound on film. For high school and college groups.
Illustrates dynamic aspects of stars within our galaxy and of galaxies themselves by use of animated drawings. Includes changes in the Dipper, binary stars, eclipsing variables, trinary stars, motion of stars in the Hyades and Hercules clusters, apparent star motion due to motion of the solar system, galactic rotation, and a portrayal of the theory of the expanding universe. Also describes the principles of refracting and reflecting telescopes.

Summary:
Portrays how heart and blood vessels circulate blood throughout the body. Animated drawings depict the nature of the circulatory system and muscular and valvular heart action. Reveals factors affecting the rate of heart beat, flow of blood from a severed artery, and the effect of severing the cervical nerve. Through cinemicrography discloses capillary blood flow. For high school, college, and adult groups.
