Abstract Electronegativity is an important concept of the module “structures and properties of matter” which belongs to chemistry optional compulsory course in senior high school. This lesson uses the “project-based learning” approach. In the process of experiment, through analysing, discussing the harm and removal of formaldehyde, it can enhance students' understanding of electronegativity and mastering the method of using electronegativity to analyze and predict the chemical properties of substances. At the same time, it can help students experience the use value of the concept of electronegativity.
