Why are some reactions in the world around us irreversible? How is the flow of electrical energy in a complete circuit like water flowing over a waterwheel? In Chemical Reactions & Electricity, viewers observe chemical reactions in nature and in the laboratory to uncover the difference between physical and chemical changes They use models and travel to huge electric plants to explore the various parts of an electrical circuit, and see how current flows to provide the power we need to keep our world in motion!
