一、教材和学情分析1.教材分析“镁的提取及应用”是普通高中课程标准实验教科书化学1(苏教版)专题2“从海水中获得的化学物质”的第二单元,此专题以海水资源为背景,以“工业生产—性质探究—社会应用”为线索,从工业生产实际出发,通过实验探究,引出典型的金属元素——钠、镁单质及其化合物知识。让学生在认识物质性质的同时学会认识物质的方法,从中体会化学为人类社会发展做出的巨大贡
First, the textbook and learning analysis 1. Textbook analysis “Magnesium extraction and application ” is the ordinary high school curriculum standard experimental textbook chemistry 1 (Sujiao Edition) topic 2 “obtained from seawater chemical ” second Based on the background of seawater resources, taking “industrial production - nature exploration - social application” as a clue, starting from industrial production practice, this project leads to the discovery of typical metallic elements - sodium and magnesium and their compounds know how. To enable students to understand the material nature of the same time, learn to understand the material method, from which to understand the great contribution made by chemistry for the development of human society
