课程名称：化学与工业 课程概述： 化学通常被定义为研究物质的性质和用途的科学。物质是指任何具有质量并能占据空间的东西。然而，化学课程应以学生易于理解的方式呈现。通过多年的教学和研究经验，我发现许多学生对化学缺乏正确的认识。例如，在一次访问家庭经济实验室的过程中，我要求一名学生拿来食盐（氯化钠）加入食物，结果让大多数学生感到惊讶，甚至以为这是有毒物质。统计数据显示，95%的学生未能及格，这使我意识到，许多人第一次了解到平常的厨房盐就是他们在化学课堂上提到的氯化钠。 因此，我采用了“让化学变简单”的教学方法，让学生更加容易掌握这门科目。化学的知识在化学工业中至关重要，它帮助化学工业将其他化学物质转化为可用的化学品。 课程内容包括： 1. 化学工业的发展 2. 化学职业机会 3. 化学工业的分类 化学工业生产多种产品，因此我们可以根据其产品将其分类： 1. 基本化学品，如酸、碱、盐和有机化学物质 2. 用于制造人造纤维和塑料的化学产品 3. 作为其他工业的原材料的化学产品，例如制造油漆、肥料、炸药、药物、肥皂等的行业 化学工业的划分包括： 1. 重化学 2. 精细化学 3. 肥料 4. 塑料 5. 金属冶炼等 这门课程旨在帮助学生更好地理解化学及其在工业中的应用，同时开阔他们的职业视野。
DEFINITION OF CHEMISTRYIn general, Chemistry can be define as a science subject which deals with the study of properties and the uses of matter.WHAT IS MATTER? Matter is any thing that have mass and can occupy space.But then, chemistry class should be presented to students in such a way they will understand it better. This is what I discovered in my years of teaching and research experience.Years ago i encountered experience with some chemistry students in a full school. When I walked into a Home Economics laboratory where they were offering some classes on how to cook some foods. Then, I asked a students to bring sodium chlorine to add to the food. They where all surprised. Thinking I wanted to harm them. That sodium chloride is poisonous. Statistically, 95% of students failed. They all learnt for the very first time the cooking salt which is the normal salt is what they see or hear almost everyday in chemistry classroom.A good logical approach will make students to find chemistry easier. My methodology ‘'Make Chemistry Easy''.The knowledge in chemistry helps chemical industry to make chemicals from other chemical substances.This Lectures features:1. Development of chemical industries2. Career Opportunities In Chemistry3. Division Of Chemical IndustrySince the chemical industry produces a variety of products. It is useful to classify the industry on the basis of its products. We have chemical industries which produce;1. Basic chemicals such as acids, alkali, salts and organic chemical2. Chemical product that are use in the manufacture of artificial fibres and plastics3. Chemical product use as starting material in other industries that manufacture substances such as paints, fertilizers and explosive, drugs, soap e.t.cThe divisions of chemical industries are;1. Heavy chemicals2. Fine chemical3. Fertilizers4. Plastics5.Metallurgye.t.c
