实验是化学学习的基础和灵魂,课堂演示实验是化学教学的重要内容,也是高考实验题的“题源库”从演示实验中挖掘命题点,是体现“实验源于教材、高于教材”思想的重要措施,也是近几年高考实验的一大亮点。因此,高三复习必须认真剖析研究课本中的典型实验,研究高考实验题,采用类比、拓展、归纳迁移的方法,引导学生找出实验的 Experiments are the basis and soul of chemistry learning. The classroom demonstration experiment is an important part of chemistry teaching. It is also the key point of the college entrance examination experiment questions. It is the embodiment of the experiment that the experiments are derived from the textbooks, Teaching material "an important measure of thought, but also a major highlight of college entrance examination experiment in recent years. Therefore, the senior high school review must carefully analyze the typical experiments in textbooks, research college entrance examination questions, the use of analogy, expand, summarize the method of migration to guide students to find out the experiment
