初中物理涉及到大量的实验,本人结合自己的教学经验,把山东科学技术出版社出版的义务教育课程标准实验教科书(五四制)《物理》中出现的一些典型实验进行分析,以供同仁参考。一、控制变量法这是初中物理出现最多的实验方法,要求学生掌握、理解、应用的实验有:1.探究影响滑动摩擦力大小的因素的实验:2.影响压力的作用效果的因素的实验;3.影响液体内部
Junior high school physics involves a large number of experiments. I combined my own teaching experience with the analysis of some typical experiments that appeared in the physical education textbooks (four-fourth system) “Standard Physics” published by Shandong Science and Technology Press for reference. . First, the control variable method This is the most experimental method of junior high school physics, the students are required to master, understand, apply the experiment are: 1. To explore the factors that affect the size of the sliding friction experiment: 2. The experiment of factors that affect the effect of the pressure effect ;3. Influencing the internal liquid
