Abstract Under the concept of “structure determines nature”, this course is based on the “exploring the structure of flammable ice” to teach “using multiple theoretical models to analyze, explain and predict the spatial structure of molecules”,taking “combustible ice” as the object of study. Through three core activities including “recognition of methane molecule, using ‘balloon’ to recognize water molecule and recognition of ‘ice cage’ consisted of water molecule”, this course constructs a thinking path, which utilizes hybrid orbital theory model and hydrogen bond model jointly to interpret molecule structure and utilizes valence shell electron pair theory model to predict molecule structure. The final goal is to reveal the diversity and complexity of the covalent molecule through the process of solving actual problems.
