化学是一门以实验为基础的自然科学。化学中的结论、规律都是科学家通过一次又一次的实验在实践中不断探索、归纳、总结出来的。学习化学就要密切联系生活实际,同时进行必要的化学实验。化学实验是进行直观教学的有效方法。通过实验可以观察到鲜明的现象,得到丰富的感性知识。在化学教学中要重视化学实验的教学,注意培养学生的观察、思维、实验的能力, Chemistry is a natural science based on experimentation. The conclusions and laws in chemistry are all continuously explored, summarized, and summed up in practice by scientists through experiments one after another. Learning chemistry should be closely linked with the reality of life while conducting the necessary chemical experiments. Chemical experiment is an effective method for intuitive teaching. Through the experiment, clear phenomena can be observed and abundant perceptual knowledge can be obtained. In chemistry teaching, we must pay attention to the teaching of chemistry experiments, and pay attention to the ability of students to observe, think, and experiment.
