Abstract Guided by whether Fe undergoes displacement reaction with CuO, experimental exploration was conducted on iron powder and CuO, proving that Fe could undergo displacement reaction with CuO, and product identification was carried out. Furthermore, the control variable method was utilized to optimize the experimental conditions and solve the problem of unclear experimental phenomena. The exploration activity was guided by questions, allowing students to make bold conjectures and hypotheses, and use experiments to verify and falsify them. The experimental information was processed to obtain conclusions, which was expected to cultivate the scientific spirit of independent thinking, daring to question, and daring to innovate in high school students during the experimental exploration process.
