Abstract This unit teaching is based on the concept of deep learning, focusing on the common core concept of “structure determines property, and property determines application” in chemistry and biology. Based on the lower level interdisciplinary concept of “the essence of life activities is the interaction between particles”, this paper explores the differences and connections between the understanding of properties in chemistry and biology courses, thereby developing a structured understanding of the core concept, that is, understanding that the core concept is the specific embodiment of core competencies in chemistry such as “macroscopic identification and microscopic analysis” and biology such as “structural functional view”, promoting the integration and development of core competencies in chemistry and biology among students. Taking “designing low glycemic index zero calorie sugar substitutes” as the driving task, a series of core learning tasks are developed for students’ interests in sugars and sugar substitutes. Key questions with internal logical connections, such as “understanding the properties and main functions of sugars from the perspective of chemical bond”, “why sugar substitutes are sweet”, “how to obtain zero calorie sugar substitutes”, and “dialectical understanding of sugars and sugar substitutes”, are developed and refined into learning activities that promote students cognitive development.
