一、教材分析本节内容为人教版选修4《化学反应原理》第四章第1节原电池。首先回顾必修与本章前两节相关知识,认识哪些反应可以设计成原电池,初步理解原电池和电解池在结构上的区别,通过分析具体的氧化还原反应,初步了解选择简单原电池电极材料的依据。通过实验探究,使学生认识化学能不仅可以转化为热能,而且通过原电池装置可以把化学能转化为电能。通过这节课,学生可 First, the textbook analysis This section is the PEP 4 elective 4 “Principles of Chemical Reactions,” Chapter IV of the original battery. First of all, we must review the relevant knowledge of the first two chapters of this chapter, and understand which reactions can be designed as the primary battery, to understand the difference between the primary battery and the electrolytic cell. By analyzing the specific redox reaction, in accordance with. Through experimental exploration, students can recognize not only chemical energy can be converted into heat, but also through the original battery device can be converted into electrical energy into electricity. Through this class, students can
