Abstract In order to solve the real problem of “why glass stopper is not used in reagent bottles to preserve NaOH solution”, three teaching sections are designed: using classification methods to recognize substances,classify substances and synthesize substances. From the perspective of material composition and material change, this paper classifies materials and constructs the classification view. In addition to completing the knowledge structuring, it focuses on the cognitive perspectives and ideas based on the classification and transformation of substances, finds and experiences the breakthrough point and thinking framework for the study of new substances in unfamiliar situations, and develops students' core literacy of chemistry discipline.
