一、改进实验　实现创新中国科学院院士朱兆良说过 :“如果人云亦云 ,就永远不会超越 ,只有形成自己的思路、思想 ,多方面看问题 ,才能超出前人”。如高一化学 (新教材 ,下同 )第二章《钠》教材中有这样一个学生实验 ,切一小块钠 (绿豆大 ) ,用铝箔(事先用针刺一些小孔 )包好 , First, to improve experiments to achieve innovation Chinese Academy of Sciences Zhu Zhaoliang said: “If people are in a cloud, they will never exceed them. Only by forming their own ideas and ideas and looking at problems in many ways can they exceed their predecessors.” For example, there is such a student experiment in the “Sodium” textbook in the second chapter “Sodium Chemistry” (New Teaching Material, the same below). Cut a small piece of sodium (mung bean) and wrap it with aluminum foil (previously pierce some small holes).
