Abstract Using“Tofu-Making”as the central activity,the teaching process comprises three tasks to deliver instruction on colloids.The Tyndall effect is observed and analyzed to identify colloidal properties through“Soy Milk Colloid-Discovering Colloids”.Diverse coagulation methods are then employed to demonstrate particle aggregation and electrophoresis,revealing colloidal structure and exploring different coagulation principles in“Coagulation Technique-Precipitating Colloids”.Finally,the applications of colloidal coagulation principles are expanded while drawing life analogies from tofu craftsmanship in“Savoring Tofu-Triple Reflections”.This process achieves dual objectives:internalizing colloidal knowledge and solving real-world problems.A competency cultivation mode integrating“Cultural Heritage-Scientific Inquiry-Value Guidance”is established,seamlessly combining task-driven learning,experimental exploration,and ideological education.It elevates students’ core chemical literacy and cultural confidence.The project-based context and task design significantly enhance learning engagement,facilitate knowledge transfer,and deepen appreciation for Chinese traditional culture.It offers a replicable pathway for project-based chemistry instruction,preserving excellent traditional culture and synergizing it with ideological and political education in the curriculum.
