摘　　要：介绍了作为2023年中国科学技术大学科技周化学与材料学院科普点的志愿者,在准备“树叶电镀”科普实验时,如何经历重重失败,克服种种困难,最终顺利完成“树叶电镀”项目的经历,以及在此经历中的感悟与收获。“树叶电镀”实验是受艺术性的树叶书签之启发,主要利用化学镀与电镀原理,目的在树叶表面均匀镀上一层铜的科普实验。通过该实验,观众可初步了解氧化还原反应及电化学的初步知识,激发小朋友们对于化学的兴趣。This article introduces how the authors,as volunteers at the Experimental Chemistry Education Center of the University of Science and Technology of China,overcame various failures and successfully completed the“Leaf Electroplating”project for the 2023 Science and Technology Week,as well as the insights and gains gained from this experience.The“Leaf Electroplating”experiment is inspired by the artistic art of leaf bookmarks,mainly using principles of chemical plating and electroplating,with the aim of uniformly plating a layer of copper on the surface of leaves as a popular science experiment.Through this experiment,the audience can gain a preliminary understanding of redox reactions and electrochemistry,stimulating children’s interest in chemistry.
