Abstract The interdisciplinary project course is designed with colloidal gold as the material. Students understand the structure, properties and applications of colloidal gold by completing three sub tasks: “exploring the principle of COVID-19 test strip”, “research on the synthesis and stability of colloidal gold”, and “designing an ampicillin detection method based on colloidal gold”. Through continuous reflection activities, students can promote their understanding of key knowledge, develop their thinking and methods in the field of chemistry, and enhance their innovation awareness. This project course is related to interdisciplinary concepts such as “scale, proportion, and quantity” and “structure and properties”, as well as the core knowledge of chemistry and biology. It guides students to understand matter and its changing laws in a broader disciplinary context, cultivates their ability to analyze and solve practical problems, and comprehensively develops the core literacy of chemistry.
