Abstract This paper takes exploring the industrial capture scheme of carbon dioxide as the project theme, and carries out the teaching of the nature and transformation of chemical carbon dioxide in junior high school. Students understand the relationship between “composition, properties, and change ”of matter through three projects subtasks of the “valence of material classification two-dimensional model and design the ideal of carbon dioxide conversion path” “experiments to explore the practical transformation of carbon dioxide” “to solve the industrial transformation of carbon dioxide”. The absorption efficiency of carbon dioxide in different alkali solutions is investigated by digital experiment with handheld technology, develop the ability of experimental inquiry, construct the cognitive model of material transformation in the field of chemical production, and improve the ability of thinking transfer. The advanced problem-solving mode from “carbon capture” to “carbon utilization” is conducive to the internalization of students' core literacy.
