539-551.2 EDUCATIONAL FILM CATALOG 539 Molecular physics Molecular theory of matter. (Univ. of Chicago physical science ser.) lOmin 16-sd-$50 35-sd-nf-$100 1932 Erpi 539 By Dr Hermann I. Schlesinger and Dr Harvey B. Lemon of the University of Chicago "E>vidence of molecular activity in gases, liquids, and solids is presented in support of the molecular theory of matter. Animated drawings explain such pheno- mena as the diffusion of gases, the evapora- tion of liquids, and the transformation of liquids into solids, in terms of the theory. Among the features of the film are the machine gun illustration of the force exerted by molecules in motion, and the microscopic view of the Brownian move- ment, direct evidence of molecular mo- tion.

Lemon of the University of Chicago "The simultaneous process of oxidation and reduction is presented first by burning phosphorus and rusting iron under experi- mental conditions. Mercury rust is then de- composed to discover the component of air responsible for oxidation. Other examples of oxidation and oxidizing agents follow. The process of reduction is strikingly pre- sented in the operation of the blast fur- nace, magnesium burning in dry ice, and thermite welding. Everyday examples of oxidation and reduction conclude the pic- ture."

Erpi 551 "Presents physiography in its dynamic aspects, and aims to show that the same forces which have shaped the earth as it is today are still at work further changing it. In the slower processes, this effect is obtained by the use of models and dia- grams, which show a thousand year process taking place in a few seconds. The part the Water Cycle plays in shaping the earth is emphasized. "The formation of igneous, sedimentary, and metamorphic rocks is clearly illustrated by models and animated diagrams. The ceaseless action of those forces which cause mountains to crumble and become soil are plainly shown." Harvard jh-sh-c Guide Our earth.
