现行上海教育出版社《九年级化学第一学期(试用本)》第97页安排的“燃烧的条件”演示实验,是初中化学一个重要的探究性实验,是学生运用科学的思想方法探究以及建构燃烧需要哪些条件的一个经典实验。该实验现象明显、操作简便,体现了控制变量思想和对比思维,有利于学生认识燃烧的条件,同时红磷、白磷的出现也为后续学习同素异形体的埋下伏笔。但该实验也存在一些不足。课本上“燃烧的条件”实验装置如图。用
Current “Shanghai State Education Publishing House,” the first semester of ninth graders (trial version) “97 pages of the” burning conditions “demonstration experiment, junior high school chemistry is an important exploratory experiment, the students use the scientific method of thinking to explore As well as building a classic test of what conditions need to burn. The experimental phenomenon is obvious, easy to operate, reflects the control variables thinking and comparative thinking, is conducive to students to understand the combustion conditions, while the red phosphorus, white phosphorus for the follow-up study of alloptical form of the foreshadowed. However, there are some deficiencies in this experiment. Textbook ”combustion conditions " experimental device shown in Figure. use
