一、培养学生的安全防范意识培养安全防范意识是顺利地完成实验的关键。一些实验安全事故的发生或多或少地影响着化学实验的正常进行。甚至一些学校为了避免学生受到这种负面影响所带来的伤害,采取了减少学生进行试验操作的措施。这种因噎废食的手段间接性地阻碍了化学实验的发展,局限了学生的思维空间和动手能力。其实只要我们能够正确地掌握实验操作过 First, training students to raise awareness of safety precaution is the key to successful completion of the experiment. Some experimental safety accidents more or less affect the normal chemical experiments. Even some schools have taken measures to reduce the number of students conducting experimental operations in order to avoid harming students from such negative impacts. This impotent means indirectly hindered the development of chemical experiments, limited the students’ thinking space and ability. In fact, as long as we can correctly grasp the experimental operation
