Abstract Based on the current situation of high school students' difficulty in understanding the experiment curve, in order to tap the teaching value of the experimental curve, this paper took precipitation dissolution equilibrium as an example, designed an experimental inquiry course of “macro- micro-symbol-curve” multi-representation model through classroom demonstration experiments and teaching software. Based on the experimental evidence of precipitation dissolution equilibrium, the experimental curves were drawn, microscopic models and images were constructed, so as to cultivate students' awareness of evidence collection and application, improve students' ability to analyze and understand curves, and understand the source of various curves. Combining the curves to understand and establish a “dissolution-balance-transformation” thinking model, so as to provide reference cases for the problem-oriented experimental teaching of “curve integration”.
