Abstract With the theme of “I am a zero carbon methanol engineer” and the driving task of “designing a zero carbon methanol production plan”, teaching is carried out under the guidance of the concept of “material change and transformation”. Through the study of this project, while learning core knowledge such as the law of conservation of mass and chemical equations, students will be guided to establish a mindset of understanding chemical reactions through the use of mass relationship and proportional relationship. The purpose is to achieve functional learning of chemical equations by integrating the learning of chemical equation knowledge with the establishment of a quantitative understanding of chemical changes, and finally students can gain a deeper understanding of the importance of rational use of substances and regulation of chemical reactions through computational deduction.
