Based on the integration of chemistry history, this paper puts forward the five-line teaching mode. The five lines in the “five-line” teaching mode are “historical line”, “problem line”, “activity line”, “knowledge line” and “literacy line”. In teaching, the author should follow the principle of systematization principle, authenticity principle, moderation principle and educational principle. Chemistry teachers can create a situation with chemical history events, use situations to ask questions, rely on chemical experiments and classroom discussion and other activities to help students acquire knowledge, and then cultivate students’ core literacy of chemistry. Taking the section of “primary battery” as an example, along the chemical history of discovering animal current, which photovoltaic invented photovoltaic reactor and Daniel invented the double liquid primary battery, we help students to realize the construction of single liquid primary battery and double liquid primary battery model.展开更多
