1962
Main contributors:
Ellis Katzman, Elbert C. Weaver, John A. Skarulis, William H. Pasfield, Ross Lowell, Herman J. Engel, Robert Braverman, Peter Robinson, Geraldine Lerner, Max J. Rosenberg, Fisher Scientific Company
Summary:
Demonstrates the differences between saturated, unsaturated, and supersaturated solutions; that solutions are dynamic, not static in character; and also shows suspensions and colloidal dispersions. Presents characteristics of solutions and explains insolubility, solutions without chemical reactions, mixtures, suspensions, and the Tyndall effect in colloidal dispersions.

142. Editing Synchronous Sound (10:46)

Date:
1960
Main contributors:
Indiana University, Bloomington. Audio-Visual Center
Summary:
Explains the process of editing motion picture footage in double system synchronous sound motion picture production. Follows, through use of flashbacks, the step-by-step sequences from the use of a clapstick to establish synchronization cues during shooting; the use of this visual-auditory signal to re-establish synchronization for each "take" during editing; means of permanently marking these head synchronization points; to the usefulness of the gang synchronizer and means of establishing internal synchronization points. Animation is employed to illustrate maintenance of synchronization in cutting from one take to another and means of elimination of unwanted sound in the sound track.

143. Egypt : a country in transition (10:34)

Date:

Summary:
Shows a family and its household slaves engaged in their early morning tasks. Depicts the work involved in maintaining the home and reveals lack of many conveniences. Dramatizes the relationships that existed among the master of the household, his family, and his slaves.

145. Electricity. Distribution (16:06)

Date:
1962
Main contributors:
Indiana University. Audio-Visual Center
Summary:
Develops basic concepts of electrical distribution, both cross-country and within the home. Complete distribution system is explained, with demonstrations of "line loss" and the use of fuses for overload protection. Reviews parallel and series circuitry. Summarizes, using questions.

146. Electricity: Measurement (12:14)

Date:
1963
Summary:
Develops concepts of electrical pressure, current, and resistance, and establishes the need for the measurement of electricity. Demonstrates the measurement of electrical pressure and current flow, shows the development and use of Ohm's law in calculating electrical relationships, and discusses the importance of fuses as a safety measure.

147. Essentials of good speech : colors 1 (11:00)

Date:
1974
Summary:
Discusses a well-known system for practicing pronunciation: articulation of consonants and enunciation of vowels. Emphasizes again more "parts" which are to be applied to "wholes." Shows how sounds are associated with a color code: blue for voiceless, red for voiced, and brown for nasal manner of articulation. Illustrates an early lesson at the "Presentation Stage" and introduces specific touch positions for color work.

148. Essentials of good speech : colors, 3 (11:10)

Date:
1974
Summary:
Discusses shaping the pronunciation of vowels and consonants. Depicts the teacher helping the pupil combine voiced and nasal consonants with long vowels. Also presents more difficult sound combinations, including short vowels.

149. Essentials of good speech : colors, 4 (13:16)

Date:
1974
Summary:
Demonstrates one pupil's accomplishment of the early goals of color work: pronunciation of vowel and consonant combinations. Depicts a pupil producing the majority of speech sounds on request, and imitating (shaping) some complex sounds: "SH", "R", "L", and "S". Discusses the application of "part" learning to the pronunciation of a new word, "talent," which the pupil sees in print.

150. Essentials of good speech : duration 1 (13:11)

Date:
1974
Summary:
Explains the contents of the Essentials of Good Speech. Discusses duration as an aspect of voice production and how it refers to the length of sound. Illustrates a lesson on duration at the "Presentation Stage" of Face A of the Speech Model. Shows the pupil learning a "part" (Duration) which will later be applied to a "whole" (word or words).
