Abstract In the teaching of the concept of “saturated solution” in middle school chemistry, it is easy to ignore the pre-concept of students, the process of construction and the mining of the essential principle behind the concept, and often rely on experiments to construct the concept, so that students can't fully understand the essential principle of the concept. This paper attempts to create a model, combine the model with the experiment, and explain or predict the experiment with the model to help students better construct and understand the concept and essence of “saturated solution”.
