Abstract This teaching case is an example of project teaching and learning activity based on the reducibility of vitamin C for the grade 1 students in high school who has learned the basic knowledge of redox reaction. Firstly, the project issue is raised by the teacher and students design the plan of solving it which is devided into several sub research tasks through the guide of teacher. Then, students carry out their sub research tasks to assaying the vitamin C in the lemoade. The project is aimed at strengthening the thought anagle of material's oxidability and reducibility, building the experiment thought of assaying the target molecule or other chemical materials, enhancing the know of the functions and values of redox reaction.
