“蜡烛燃烧”是初中化学课程中一个核心的探究活动,承载了许多物理、化学知识。在细致研究课标、比较四个版本教材的基础上,抓住“物质燃烧的条件”所蕴涵核心知识的逻辑关系、科学方法和化学思想,围绕知识的价值和学生的思维有逻辑地以“蜡烛的燃烧”设计学生实验活动,着重培养学生的设计实验能力、观察能力和化学思想和观念。 “Burning candle ” is a core inquiry activity in junior high school chemistry course, carrying many physical and chemical knowledge. On the basis of careful study of the standard of the lesson and the comparison of the four versions of the teaching materials, we should grasp the logical relations, scientific methods and chemical thoughts of the core knowledge contained in “the conditions of material burning”, and focus on the value of knowledge and the thinking of the students logically The “candle burning” design student experimental activities, focusing on developing students’ ability to design and experiment, observe the ability and chemical ideas and concepts.
