Abstract The new curriculum standards emphasize improving students’ comprehensive abilities. Interdisciplinary project-based learning can break down disciplinary barriers and guide students to conduct experimental inquiry through driving questions and activity tasks. Based on the characteristic that both enzymes and chemical catalysts reduce reaction activation energy,this project explored the effects of different reaction conditions (such as temperature,concentration,and pH) on the activities of enzymes and ferric chloride (FeCl3) through a series of experiments. A cognitive model for regulating chemical reaction rates with catalysts was constructed and applied to innovative design. This approach helps students overcome the cognitive difficulty of “regulating catalyst activity to affect chemical reaction rates” and deeply understand the application value of catalysts.
