Two light polarized filters used with an overhead projector can create the suggestion of movement in transparencies. The technique is described and sources of polarized materials are given. (MS)

Illustrated. (RD)

Presents some suggestions for getting maximum use and benefit from sixteen millimeter films. (AN)

Describes film cartridges and cassettes and commercial machines designed to project them; illustrated; based upon a report to the Board of Trustees, American Film Institute. (Editor/SW)

Suggestions are provided for using color television projector systems to demonstrate color mixing. With such a projector, manipulation of the three primary colors can be done by simply covering and uncovering the three separate beams. In addition, projector systems serve as good examples in studying geometrical optics. (Author/JN)
