化学是一门以实验为基础的学科。在平时的教学中,教师往往通过神奇的化学实验把学生引入课堂,同时,又通过变化莫测的化学反应把学生领出迷宫,探究问题的实质。化学实验的成与败,牵动着每一位学生的心弦。化学教育者要想引领学生探究化学世界,实验教学是关键。笔者从事化学教学工作十几年,在实验教学中做了多种尝试。有些实验受化学反应原理的限制,实
Chemistry is an experiment-based discipline. In normal teaching, teachers often use magical chemistry experiments to introduce students into the classroom. At the same time, they lead the students through the maze through unpredictable chemical reactions to explore the essence of the problem. Success and failure of chemical experiments affect the hearts and minds of every student. Chemistry educators want to lead students to explore the chemical world, experimental teaching is the key. I engaged in chemistry teaching more than 10 years, made a variety of experiments in experimental teaching. Some experiments are limited by the principles of chemical reactions
