Abstract Exploring activities and learning experiences mainly based on chemical experiments are important ways to learn chemistry. Taking “laboratory production of carbon dioxide” as an example, four teaching stages were designed, including “reaction principle” “generation device” “collection method”, and “verification method”, to model the general ideas and methods of laboratory gas production. In class, three student activities were created to allow them to fully engage in manual and mental experiences; Three experimental explorations were also created to address three cognitive conflicts. In such a classroom, students developed multidimensional and authentic inner experiences such as perception, thinking, emotion, will and values, gradually formed chemical ideas, scientific thinking, questioning spirit, and innovative consciousness, thereby transformed their learning methods.
