Scientific Research Thinking Cultivation of Junior Students Based on Copper Plated on the Iron Nail Surface

Xingzhi College, Zhejiang Normal University, Jinhua 321004, Zhejiang Province, P. R. China

Taking copper plated on the surface of iron nail as an example, the problems of uneven copper coating and easy falling off from the iron surface were discovered based on the direct redox reaction of Cu²⁺ and Fe. On the basis of these problems, the students reviewed literatures, analyzed the problems, designed related experimental schemes, and performed experimental operations under the guidance of tutors, the problems were resolved and a uniform copper coating surface was obtained. Via the considerations of the problem discovery, problem analysis, literature review, experimental design, and problem resolving, junior students' scientific research thinking were cultivated.
