National Research Council (U.S.). Committee on Scientific Aids to Learning

These recordings were made in 1941 for an experiment in the use of audio/visual aids for science teaching in the Rochester, NY, schools under a grant-in-aid from the Committee on Scientific Aids to Learning of the National Research Council.

Philip Rulon narrates the soundtrack to slide shows on various elementary scientific topics, Air, Gases in the Air, The Weather, Water Supply, and Heating Our Homes. The "A Side" (Part 1) and "B Side" (Part 2) of each disc cover the same material slightly differently. Possibly they recorded 2 takes per subject or a variation on the script which was part of the study. The voice on fourth record, The Water Supply sounds very different from the other four. Perhaps someone filled in for Philip Rulon during that recording session.

Produced by Jerome J. Rulon, director, Sound Slide Film Study, Graduate School of Education, Harvard University
