化学是一门以实验为基础的自然科学。通过实验,我们可以观察到大量生动、有趣的化学反应现象,从而了解大量物质变化的事实。学会实验基本操作是进一步运用实验方法去验证和探索物质的性质和变化规律的基础。化学实验基本操作的知识并不难理解,但由于这部分知识多而零散,对于刚学习化学缺乏实际操作经验的初三学生来说,在学习和实验时存在一定的困难。在教学过程中将枯燥苛刻的基本 Chemistry is a natural science based on experimentation. Through experiments, we can observe a large number of vivid and interesting chemical reaction phenomena, so as to understand the fact of a large number of material changes. Learning the basic operation of experiments is the basis for further using experimental methods to verify and explore the nature and laws of change. The knowledge of the basic operation of chemical experiments is not difficult to understand, but because this part of the knowledge is scattered and scattered, it is difficult for students who are just learning chemistry to lack practical experience to study and experiment. In the teaching process will be boring harsh basic
