Chemical Changes All About Us (Special Version, 1960)

The film explores the concept of chemical changes by comparing everyday kitchen activities, like baking a cake, to laboratory experiments. It explains how elements such as sulfur and iron can undergo chemical transformations when heated or mixed with other substances, resulting in new compounds. The film highlights various examples, including the formation of iron sulfide, calcium hydroxide, and magnesium oxide, and discusses the role of energy in these changes. It emphasizes that chemical changes occur constantly in our lives, from cooking to biological processes and even in machines.
