氧化还原简案（Redox scenario） [teaching purposes] 1.. Consolidate the knowledge of four basic reaction types in junior high school. 2.. Consolidate the knowledge of oxidation reaction and reduction reaction in junior high school. 3., develop students discussion style learning methods and cultivate students reading ability. 4., through classroom exercises to understand the junior high school students grasp the situation. [teaching emphasis] strengthen the knowledge of the classification of chemical reaction in junior high school and the knowledge of the main reaction types, and deepen their understanding. [teaching difficulty] the training of students discussion learning methods. [Methods] review and guide method [teaching means] projection [teaching process] Section A [story] in junior high school history class, we learned that human progress and development are closely related to fire, and the exploration of combustion is an old and young subject, which has been studied in the past, present and future. The study of reactions in combustion, energy change, combustion efficiency, and the effects of products on the environment are closely related to the knowledge in this chapter. [projection blackboard writing] Chapter 1 chemical reactions and their energy changes [story] the burning of junior high school refers to the oxidation of the alkene and the oxygen in the air, and the oxidation of the heat. Now we will study further. Abstract: junior high school learning projection blackboard is the reaction of CO2 is the chemical reaction of C+O2 oxidation reaction, visible on the chemical reaction can be classified from different angles, the purpose is to understand the various types of reaction essence. [projection blackboard writing] first, the type of chemical reaction [story] junior high school mainly studied two different chemical reaction classification methods: basic type reaction and oxidation reaction, reduction reaction. [projection writing on the blackboard] 1. basic typ
