在化学教学中如何实现创智课堂,如何挖掘教材发展学生的智慧是化学教师一直思考的问题。石灰石是沪教版化学九年级上册第五章第四节。在前几章节的学习中,学生不仅对物质的组成及表示方法、质量守恒定律、化学方程式等基础知识有了一定了解,对化学实验等探究性学习活动有了一定的实践体验,而且学生对石灰石与稀盐酸的反应、澄清石灰水与二氧化碳的反应、生石灰与水反应、一氧化碳还原氧化铜等知识已经有了一定的认识。石灰石这节内容的新知识为碳酸根的检验和碳酸钙
How to Develop Intellectual Wisdom Class in Chemistry Teaching and How to Develop Materials to Develop Students’ Wisdom is a question that chemistry teachers always think. Limestone is a Shanghai Jiao Tongjiujiu ninth grade on the fourth chapter of the fifth chapter. In previous chapters, students not only understood some basic knowledge of material composition and representation, conservation of mass, and chemical equations, but also had some practical experience in exploratory learning activities such as chemical experiments. Limestone and dilute hydrochloric acid reaction, to clarify the reaction of lime water and carbon dioxide, lime and water reaction, carbon monoxide reduction of copper oxide and other knowledge has been a certain understanding. The new knowledge in this section of limestone is Carbonate Inspection and Calcium Carbonate
