模拟实验是指客观条件不能对某些自然现象进行直接实验,只能借助间接的手段,先设计一个与需要研究的自然现象(原型)相似的“模型”,然后通过对模型的研究间接认识原型的规律的实验。模拟实验在高年级82个实验中占16个,约占20％,不难看出模拟实验是自然教学中一项重要内容,第九册20课《雾和云》一课,对“白气”成因的模拟实验是高段第一个模拟实验。这个模拟实验,同时又是对比实验,既要体现模拟实验的教法,又要体现对比实验的教法,这个模拟实验
The simulation experiment means that the objective conditions can not directly test certain natural phenomena. Only through indirect means can we design a “model” which is similar to the natural phenomenon (prototype) to be studied, and indirectly recognize the prototype through the study of the model The regular experiment. It is not difficult to see that the simulation experiment is an important part of natural teaching. The ninth volume of 20 lessons “fog and cloud” class, the “white gas” Genesis of the simulation experiment is the first high-level simulation experiment. This simulation experiment, at the same time is a comparative experiment, it is necessary to reflect the teaching of simulation experiments, but also reflect the teaching of comparative experiments, this simulation experiment
