Abstract

Abstract: 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.
