Abstract The purpose of this study is to help students understand the practical value of the methods and procedures for studying the properties of substances. With the theme of the project “exploring leavening agents”, the students are guided to break down the project into four sub-tasks, including “experiencing the application of leavening agents” “investigating the components of leavening agents” “exploring the working principle of leavening agents” and “self-made leavening agents”, through sharing and questioning, designing research tables data access, personnel interviews, steaming Mantou and other activities emphasize that students experience the problem solving process based on real and unfamiliar situations, and cultivate students' key ability to study the methods and procedures of material properties. Based on the integrated goal of “teaching, learning and evaluation”, a quantitative evaluation table of student performance is designed, and student self-evaluation, group mutual evaluation, teacher evaluation and other evaluations of student learning performance are carried out according to the scoring criteria.
