摘　　要：以铁是否与氧化铜发生置换反应为引导,对铁粉与氧化铜进行实验探究,证明铁与氧化铜可以发生置换反应,并对产物进行鉴定。进而再利用控制变量法对实验条件进行优化,解决实验现象不明显的问题。探究活动以问题为引导,让学生进行大胆猜想与假设,并用实验进行证实与证伪,对实验信息进行加工而获得结论,有望在实验探究过程中培养高中生独立思考、敢于质疑、勇于创新的科学精神。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.

关 键 词：铁与氧化铜置换反应 实验探究 控制变量法 化学学科核心素养
