1、二氧化碳的性质说课稿乐陵市第四中学聊秀双一、说教材（一）教材的地位和作用二氧化碳的性质是人教版九年级化学第六单元课题3二氧化碳和一氧化碳的第一课时。本节课主要介绍了二氧化碳的性质和用途。课程中安排了丰富的实验，通过实验探究推导出二氧化碳的性质以及二氧化碳在生产生活中的运用。学习本节课，可以进一步强化学生学习化学的科学方法，同时，它又是中考中常设计的内容，因此，在初中化学中占有一定的地位。（二）教学目标在新课程改革理念的指导下，结合对教材的分析，我制定如下三维教学目标：1、知识和技能目标了解二氧化碳的性质和用途。能设计和完成一些简单的化学实验，表达所观察到的实验现象，分析实验结论。?2、过程和方

2、法目标通过探究二氧化碳的性质，是学生经历科学探究的基本过程，进一步培养学生的观察、动手、分析实验的基本能力。3、情感态度和价值观目标通过学习，增强学生对生活和自然界中化学现象的好奇心和探究欲，提高学生学习化学的兴趣，拉进化学与生活的距离。（三）教学重难点教学重点：二氧化碳的性质及用途教学难点：二氧化碳与水、石灰水的化学反应原理二、说学情本课时内容比较贴近学生的生活，并且学生在现实生活中有了一些关于二氧化碳的知识的了解，所以学习起来不会很难。又由于学生思维活跃，求知欲强，尤其对化学实验充满浓厚的兴趣，但是学生对实验的动手和分析能力弱，还没具备自主的实验探究能力，所以我采用组成小组进行实验探究来形

3、成教学手段，逐步培养学生的实验操作能力，激发学生学习的主动性，培养严谨的科学态度。三、说教法（一）教学方法（1）情境引入法：通过创设情景，激发学生学习的兴趣，调动学生内在的学习动机，促使学生主动学习意识。文档编码:CS8T10U7E7T3 HM3H9F7J10B2 ZL4C10X10I1D3文档编码:CS8T10U7E7T3 HM3H9F7J10B2 ZL4C10X10I1D3文档编码:CS8T10U7E7T3 HM3H9F7J10B2 ZL4C10X10I1D3文档编码:CS8T10U7E7T3 HM3H9F7J10B2 ZL4C10X10I1D3文档编码:CS8T10U7E7T3 HM3H
