人教版初中物理教材中有24个比较重要的实验,虽然各个实验的实验目的不同,但有些实验所用的器材却相同;有些同一个实验却可以依据不同的实验原理,选用不相同的实验器材;还有些实验虽然实验器材和实验目的都不相同,但实验的设计方法却相同.我们把这三类实验进行分析对比,以引导学生加深对实验的理解.一、实验器材相同,实验目的不同的实验有些物理实验,尽管用的实验器材相同,但由于
There are 24 more important experiments in the physics teaching materials of the PEP Junior High School. Although the purpose of each experiment is different, some of the instruments used in the experiments are the same. Some of the same experiments can be based on different experimental principles, using different experimental equipment ; Some experiments Although the experimental equipment and experimental purposes are not the same, but the experimental design method is the same .We compare these three types of experiments to guide students to deepen the understanding of the experiment. First, the same experimental equipment, the purpose of the experiment is different Experiment Some physical experiments, although the same experimental equipment used, but due to
