化学是一门以实验为基础、以思维为主导,研究物质的组成、结构、性质及其变化规律,从而达到以应用为目的的基础自然科学课程。其基本特点是利用具体直观的实验操作活动进行形象、简单的说明,揭示化学学科的基本原理和规律,以及各种化学反应现象背后的原因和关系。我国著名化学家戴安邦教授曾说过“ Chemistry is an experiment-based, thinking-driven study of the composition, structure, nature and variation of matter, so as to achieve the purpose of the application of the basic science course. Its basic feature is the use of specific and intuitive experimental operation of the image, a simple description, reveal the basic principles and laws of chemistry, as well as the reasons behind the various chemical reactions and the relationship between.
