二氧化碳的性质探究课程的学习主要来自实验、观察、思考、总结。充分运用化学实验,通过学生实验,自主探究,形成二氧化碳的知识建构是二氧化碳的性质探究课程设计的重点。通过证明CO2密度大小实验、二氧化碳的溶解性实验、二氧化碳与水的反应这3组化学探究性实验设计,比较、探究并反思“二氧化碳的性质”实验生活化教学。
The nature of carbon dioxide to explore the course of learning mainly from the experiment, observation, thinking, summary. Make full use of chemical experiments, through student experiments, self-exploration, the formation of carbon dioxide knowledge construction is the focus of the nature of CO 2 curriculum design. Through the demonstration of the experiment of CO2 density, the experiment of carbon dioxide solubility and the reaction of carbon dioxide and water, the three groups of chemical exploration experiments were designed to compare, explore and reflect on the experimental teaching of “the nature of carbon dioxide”.
