Description: Explaining Matter - Chemical Change Produced by Encyclopedia Britannica Films Year published 1960 Grade Level: I J Distributed on media: 1 film reel (11 min.), optical sound, 16 mm. Color?Color Length: 11 MIN Description: Illustrates that a chemical change takes place when atoms from the molecules of two or more materials join with each other to form molecules of entirely different materials. Gives burning, digestion of food and plant photosynthesis as common examples.SC: Z999999, Visualizes chemical change as a continuous process by which matter is rearranged to form new substances. Uses animated sequences and a demonstration of electrostatic attraction and repulsion to reveal the inner structure of the atom and to show how chemical change can be predicted through an understanding of atomic behaviour., Uses animation and live photography to explain chemical change in terms of molecular recombinations; exhibits several common chemical changes; and emphasizes the dependence of living things upon chemical change. In detail describes chemical changes in burning and those occurring within our bodies. Analyzes, through animation, the reaction between mercuric chloride and potassium iodide. Concludes with a review and points out that all chemical changes give off and consume energy.
