Abstract This paper starts the reviewing by using the application in the chemistry experiment with gas pressure changes as a cut-in point, takes the game of ROOM ESCAPE as the situation, and summarizes the causes of gas pressure change and resulting phenomena by checking the air tightness of experimental apparatus, constructs a general model to deal with the change of gas pressure during chemical experiments, strengthens the gas pressure model by improving the instrument, which increase the functions of instrument to control the occurrence and stop of chemical reaction, analyzes and improves a classical experiment “test oxygen content in atmosphere” by using this model, proves the occurrence of reaction between carbon dioxide and sodium hydroxide solution by using this model. The design of these learning tasks highlights the experimental exploration, promotes the model construction, cultivates students’ innovative consciousness, and realizes the purpose of deep teaching and development of core literacy.
