Abstract According to the history of Boyle’s research on combustion, the combustion conditions were innovatively designed for the experimental study, and a new idea of “superposable” combustion conditions was put forward. By taking “combustion-extinguishment-control” as a main line, that conditions were a basic perspective for understanding chemical reactions was consistently articulated, and the chemical concept of substance transformation under certain conditions was implemented. Based on the idea of chemical reaction control, the field of view of reaction control of “combustion, complete combustion,slight combustion and extinguishment” was innovatively designed, and the learning activities of scenario, activity and task were integrated together. The chemistry knowledge was integrated with the fields of aesthetic education and Chinese language and culture by resetting the teaching value orientation of the experiments in the textbook and combining the aesthetics of combustion with Chinese characters.
