The basic chemical experimental courses in majors such as chemistry, chemical engineering, and materials during undergraduate education are essential for students" practical teaching and cultivating their innovative abilities. However, in the current experimental teaching process, there are still some phenomena that are incompatible with the current advocacy of energy conservation and environmental protection. This article analyzes the causes and background of some non energy-saving and non environmental phenomena in experimental teaching, combined with more than ten years of experimental teaching experience, and proposes some methods and suggestions to solve these problems based on specific situations and practical cases. During the experimental teaching process, let students understand energy-saving and green concepts through subtle means. While enabling students to acquire theoretical knowledge and develop practical ability, they should also have a deep understanding of energy conservation and environmental protection, green chemistry and green chemical industry.
