Abstract:

The traditional BZ oscillating reaction experiment focuses on the imparting of dissipative structure knowledge and the measurement of the activation energy during the induction period. Based on the rich and colorful phenomena and the underlying philosophy of life presented by the concentric circle growth process, this case study innovatively designs the experimental content supported by the dissipative structure theory, introducing the concentric circle experiment content and the flipped learning model. It aims to enhance students' scientific literacy and research abilities, guide students to analyze the safety hazards and potential environmental impacts in the experiment, integrate reflection on life into the experimental process, and utilize the principles of dissipative structures to understand and transform the world after class. The improved experiment will help establish students' correct outlook on life and the world.

Key words: Physical chemistry experiment, BZ oscillatory reaction, Concentric circle, Ideological and political education, Design of experiment
