化学是一门以实验为基础的自然学科,大部分的化学理论知识和结论都是通过反复实验得出来的。在不断的实验中,学生根据自己实验经历和经验总结,得出属于自己的化学认知。对于化学的教学,实验也是不可缺少的一个环节,大部分化学教学活动的开展需要实验来实现,学生通过直观的实验现象来感受化学蕴藏的奥妙与神奇,从而加深对化学知识的理解和记忆,掌握有效的研究方法。 Chemistry is a natural science based on experiments. Most of the chemistry theory and conclusion are obtained through repeated experiments. In constant experiments, students come to their own chemical cognition based on their own experimental experience and experience. For chemistry teaching, experiments are also an indispensable link. Most chemistry teaching activities need to be carried out experimentally. Students experience the mystery and mystery of chemical deposits through intuitive experimental phenomena so as to deepen the understanding and memory of chemical knowledge. Master effective research methods.
