While most chemical reactions take place almost immediately, there are some which can be made to occur after a timed delay. These are the so-called clock reactions. By varying the temperature or concentration of reactants, the delay can be shortened or lengthened in a striking manner.
The progress of sciences such as chemistry is due to the work of many great men. These men have made their mark in science by their curiosity and their efforts to understand natural laws. Some of these men and the fields in which they worked are: Sir Robert Boyle, properties of gases; Sir Isaac Newton, laws of motion; Antoine Lavoisier, analytical chemistry; Sir J. J. Thomson, discoverer of the electron; Jacobus von't Hoff, physical chemistry.
Changes in nature are classed as either physical or chemical changes. Examples of both types of changes are shown. Simple chemical reactions such as the burning of magnesium and phosphorous are demonstrated. Other, more complicated reactions include those of the decomposition and double displacement type.
The tale of the foolish little chicken who is hit on the head by an acorn and thinks the world is falling in is told by Poindexter and his friends. How "Chicken Little" nearly starts a panic among the animals until a sensible friend stops them is the story for today.
The Friendly Giant reads the book, Chicken Little, Count-to-ten, by Margaret Friskey, illustrated by Katherine Evans, and published by the Children's Press. After the story, Rusty shows how chickens drink. (WHA-TV) Kinescope.

Discusses how changing attitudes toward habit training are affecting the approach to learning in the schools. (University of Michigan Television) Kinescope.
Discusses the influence of the president in picking vice-presidential nominees and the difficulties in getting able men to accept this nomination. Points out that candidates are most often selected to "balance the ticket" from the standpoint of geography as well as points of view on pertinent issues. Considers the "whys" behind the nomination of seven vice presidents who eventually became president.
Huyghens (HY-gunz) discovery that Saturn is surrounded by rings which look different on earth at different times led to considerable speculation as to the nature of the rings. Some scientists believed they were solid, others maintained they were made up of particles of matter, as is actually the case. Among Huyghens’ other discoveries was the triangular expanse on Mars (“Syrtis Major”), which may be an expanse of vegetation. He also invented a very fine eyepiece, still used by physicists, which overcomes color spread. And “Huyghens Principle” regarding light spread is also constantly in use. Despite early illness and his resulting weak constitution, Huyghens was able to make discoveries that have been inestimable use to scientists who came after him.
Discusses Christianity not only as ideology, but also as a historical religion, focusing upon Jesus. Surveys the human aspects of Jesus, and contrasts standards of values in the world with the teachings of Christ.
Reviews the early years of the church when the gospel was spread by a group of ex-fishermen and tentsmen. Points out that "the good news" was not an example of the ethical teachings of Jesus, but was related to the actual experiences of the people. Discusses the concepts of the early disciples as being rooted deep in their experiences concerning incarnation, atonement, and the Trinity.
Explains the three basic symbols of Christianity--the church, the vine and branches, and the body. Diagrams the spread of the three largest Christian groups--Roman Catholic, Protestant, and Greek Orthodox--and emphasizes the main beliefs of each of these groups.
Discusses the special problems confronting the child with a chronic disorder such as hemophilia. Explains various types of chronic disorders and points out how social and emotional growth is complicated by a chronic illness. Tells how separation from parents and school, plus the medical treatment used, can bring on serious psychological problems. Stresses the importance of a wholesome relationship between the chronically ill child and his parents. Shows how educational training is provided for some children with chronic disorders. Features Dr. William Cruickshank of Syracuse University.
Ella's new stepmother discharges all the servants and forces Ella to wait on her and her two stepsisters and to sleep on the cinders. Ella's name is then changed to Cinder-Ella.

Discusses the two major aspects of the crime problem in the United States--police protection of citizens from crime and rehabilitation of juvenile offenders through training schools and reformatories. Aspects of these problems are examined by police experts, criminologists, and others. Methods of operation used by the Chicago Police Department are evaluated; training schools are visited; and their methods are contrasted with community programs designed to keep the juvenile from ever becoming a criminal.
Shows from the point-of-view of a bus driver on the job what happens during a day's run in a well-equipped city bus.
