Research work by the Bureau of Human Nutrition and Home Economics Service (United States Department of Agriculture). Chief of the Bureau Dr. Hazel K Stiebeling talks about domestic science research in the field of household equipment. A researcher put clothes into a washing machine. Another woman takes notes. Fabric sample are uniformly soiled, cut and sown onto muslin. The researcher records temperature while putting the clothes in. A woman checks the amount of dirt removed by measuring the reflected light before and after the laundry. Cooking: A woman researcher develops a standardized cake recipe to test baking performance of an electric oven. She lays the batter in pans into the oven. Judges measure the upper and lower limits of browning compared to a reference cake. Engineering test of home freezers in a laboratory. The researchers load freezer with filled cartons. Some have thermocouples inserted. A researcher checks meters and time clocks for current, energy consumption and freezer motor measurements. Researchers compare the amount of two fuels used to cook a farm family meal. (Some scenes with camera closeups have the look of 1940s and 1950s era "housewife" or homemaker scenes)
Research work by the Bureau of Human Nutrition and Home Economics Service (United States Department of Agriculture). Chief of the Bureau Dr. Hazel K Stiebeling talks about housing research. Domestic science tests on space requirements for kitchen work in the experimental housing laboratory. A researcher checks for the amount of space required to do an efficient job of home canning. An architect completes the perspective drawing for a farm house. The Regional Committee selects a group of plans. Architects and draftsmen prepare the working drawings. Architects and housing specialists check the drawings for functionality.
Research work by the Bureau of Human Nutrition and Home Economics Service (United States Department of Agriculture). Chief of the Bureau Dr. Hazel K Stiebeling talks about family economics research. Family Economics staff at work in downtown Washington. A staff member reads letters inquiring about money management techniques from families in the U.S. A staff member shows a homemaker mother how to use a food plan. They work out a weekly market list. A teacher gives a lesson in meal planning and food buying to high school seniors. Policy makers use family economic material on milk consumption during a meeting. A representative of the Bureau on a food survey. She talks to a woman at her doorstep, surveys the food in a kitchen. Information on food composition is recorded and evaluated on a sheet. A family eats a meal planned by the family economists. Dr. Hazel K Stiebeling displays various domestic arts and sciences publication for homemaker, housewife, and teachers that include food and housing research results. Other educational material includes information for the press, radio scripts, charts, film slides, motion pictures, and television programs.

Jive tune plays in the background.
Film entitled 'Scatter Radar', from The National Bureau of Standards, United States Department of Commerce. Depicts space research from the ground. The globe rotating. A satellite antenna moves into position. Radio instruments. Red optical instruments used to study the sun. Clouds in the upper atmosphere. Animation: Ionosphere reflects radio waves to the planet. A smoke of cloud rises during the launching of a rocket. An artists' conception of the Van Allen Radiation Belt above the Earth's ionosphere discovered by Explorer I and Pioneer III. A satellite orbits the globe. Men watch as a rocket is erected and fired. A scientist at the National Bureau of Standards works on a formula. A man at the controls of a scatter radar fro space research. Animation: Ionized and neutral particles as well as free electrons that permit long distance communication. free electrons reflect radio energy. Radio waves penetrate the ionosphere. A scientist at the Ionosonde model C4 to measure electron density variations. Electron density model on the monitor. Two Oxygen atoms. An electron detaches and becomes a free electron. Radio waves pass by, the electron and waves oscillate and scatter energy. Animation: Need to excite electrons sufficiently so that their energy radiated can be detected from the ground. The process requires a powerful transmitter, large antenna, and a sensitive receiver.
