化学是一门以实验为基础的学科,以实验为载体是化学教学最基本的特征。因此,化学实验在化学教学中的重要性不言而喻。一、初中化学实验的分类初中化学实验大概可归纳为以下三类:(1)有关实验室制取气体的实验。如氧气、二氧化碳的实验室制取。(2)有关基本理论和定律的探究实验。如质量守恒定律的探究。(3)有关研究物质的性质和各类物质之间的相互反应的实验。如验证二氧化碳性质的实验。但在初中化学教学中,实验教学一
Chemistry is an experiment-based discipline. Taking experiment as carrier is the most basic feature of chemistry teaching. Therefore, the importance of chemistry experiments in chemistry teaching goes without saying. First, the classification of junior high school chemistry experiments Junior high school chemistry experiments can be summarized into the following three categories: (1) the laboratory gas preparation experiment. Such as oxygen, carbon dioxide laboratory system. (2) Exploration experiments on basic theories and laws. Such as the law of conservation of mass. (3) Experiments on the nature of the material studied and on the mutual reactions between the various materials. Such as verification of the nature of carbon dioxide experiment. However, junior high school chemistry teaching, experimental teaching one
