The “Chemical Curriculum Standards” states that scientific inquiry in the chemistry curriculum at the compulsory education stage is an important practical activity for students to actively acquire chemical knowledge and recognize and solve chemical problems. It involves raising questions, conjectures and assumptions, making plans, and conducting Experiments, collecting evidence, explanations and conclusions, reflections and evaluations, expressions and exchanges, etc. Students experience personal interest in chemistry learning through personal experience and experience of scientific inquiry activities, enhance their feelings about science, understand the nature of science, and learn about scientific inquiry. Methods, initial formation of scientific inquiry capabilities. First, through the intensification of classroom demonstration experiments, creating problem situations, and developing the ability to explore
