一、教材1.教材简析《大气的压强》是初中二年物理第十一章第一节课,本节课是压强和液体压强知识的延伸扩展,使学生对压强知识进一步深化和巩固,它既符合学生认知规律由易到难,由简到繁,同时又保持知识的结构性、系统性.本节课内容包括:证明大气压强的存在的事例、大气压强的产生原因、大气压强的测量和大气压强的应用四部分内容,其中证明大气压强的存在和测量大气压强的值是本节课的主要内容;教材把实验与结论紧密地结合起来,加深学生对知识的理解,为学生利
First, the teaching materials 1. Brief analysis of teaching materials “The pressure of the atmosphere” is the first class of the physics of the second year of the junior high school. This lesson is an extension of pressure and liquid pressure knowledge, so that students further deepen and consolidate pressure knowledge. It not only meets the student’s cognitive rule from easy to difficult, from simple to complex, but also maintains the structural and systematic knowledge. This section includes: proof of the existence of atmospheric pressure, the cause of atmospheric pressure, atmospheric pressure There are four parts of the measurement and application of atmospheric pressure, in which the existence of atmospheric pressure and the measurement of atmospheric pressure are the main contents of this lesson; the teaching materials combine the experiment and conclusion closely to deepen students’ understanding of knowledge for students.
