化学是一门以实验为基础的自然科学。通过实验, 同学们可以获得大量的化学事实,加深对化学基本原理和基础知识的理解和掌握。同学们自己动手进行化学实验,一般是由提出问题、查阅资料、设计方案、动手实验、观察现象、测定数据、分析结果到得出结论。在实验中练习解决化学问题,是培养同学们提出问题、分析问题、解 Chemistry is a natural science based on experimentation. Through experiments, students can obtain a large number of chemical facts and deepen their understanding and mastery of the basic principles and basic knowledge of chemistry. The students themselves started chemical experiments, usually by asking questions, consulting data, designing programs, hands-on experiments, observing phenomena, measuring data, and analyzing the results. To practice solving chemical problems in an experiment is to train students to ask questions, analyze problems, and solve problems.
