全国统编教材初中物理第一册，热现象一章中有一个学生实验“观察水的沸腾”。该实验由于是对１００℃的沸水进行观察具有一定的危险性，又是学生接触到的较复杂的实验，要想做好实验有一定的难度，如不精心策划，不仅达不到教学目的还会出现烧伤事故，对学生今后的实验学习造?
There is a student experiment “seeing the boiling of water.” This experiment is due to the danger of observing boiling water at 100°C. It is also a more complicated experiment that students are exposed to. If you want to do a good job, there is a certain degree of difficulty in doing the experiment. If you do not plan it well, it will not only fail to reach the goal of teaching. Will there be burns accidents that will result in students’ experimental learning?
