This study employs the national intangible cultural heritage "Chu-style Lacquerware Decoration Techniques" as an authentic context, with "urushiol"—its core film-forming substance—as the knowledge and inquiry thread. Through completing five sub-tasks—"Initial Exploration of Lacquerware," "Unveiling the Secrets of Urushiol," "Scientific Improvement," "Innovative Application," and "Achievement Exhibition"—students deeply construct knowledge systems encompassing the structure, acidity, color reaction, oxidation properties of phenolic hydroxyl groups, and the characteristics of phenolic derivatives. The project integrates literature research, experimental inquiry, scheme design, and traditional cultural inheritance, fostering students' abilities in evidence-based reasoning, scientific inquiry, and innovation awareness. Students profoundly appreciate the value of chemistry in cultural heritage protection and innovation, achieving the unified development of "knowledge, emotion, will, and action" core competencies.
