开展化学实验有利于加深学生对化学反应的印象,加深学生对化学知识的理解。但开展化学实验存在一定风险,如果处理不好,就会带来安全事故。所以,提高高中化学实验操作安全具有十分重要的意义。在高中化学课程中,经常需要进行一些实验教学,通过化学实验,能够使学生对一些化学反应产生最直观的印象,加深学生对化学知识的了解。同时,化学实验还能提高化学课堂的趣味性,提高学生的学习兴趣。然而,化学实验中存在一定的风险,如一些化学物质具有腐蚀性或易 Conducting chemical experiments is conducive to deepen students ’impression of chemical reactions and deepen students’ understanding of chemical knowledge. However, chemical experiments carry a certain risk, if not handled properly, it will bring about safety accidents. Therefore, to improve the safety of high school chemistry experiment is of great significance. In high school chemistry courses, often require some experimental teaching, through chemical experiments, students can make the most intuitive impression of some chemical reactions, deepen students’ understanding of chemical knowledge. At the same time, chemical experiments can also enhance the interest of chemistry class and improve students’ interest in learning. However, there is a certain risk in chemical experiments, such as some chemicals are corrosive or easy
