摘要： 茶多酚是茶叶中多酚类物质的总称，是形成茶叶色香味及构筑茶叶保健功能的主要成分。本实验以生活中常见的茶品为引，依据茶多酚的抗氧化性及金属离子络合作用，创新设计出基于茶多酚变色反应的“茶颜悦色”与“诗情‘化’意”系列实验。其中“茶颜悦色”实验主要面向小学生，通过颜色变化展示茶多酚的抗氧化性，互动讲解中国茶的品类和相关茶文化；“诗情‘化’意”实验主要面向有一定化学基础的中学生和大学生，展示茶多酚与金属离子反应的现象，互动讲解茶多酚的提取方法和工业应用，鼓励青少年积极参与科技创新。本设计实验过程简易，可实现居家操作，实验趣味性强、安全性高；同时将传统文化融于科普实验，有助于提升广大青少年的科学素养与文化修养。

Abstract: Tea polyphenols, the primary polyphenolic compounds in tea, are responsible for its color, aroma, and health benefits. Using common tea products, we developed two innovative experiments based on tea polyphenols’ antioxidant properties and metal ion complexation: (1) “Colorful Tea Chemistry” for elementary students demonstrates antioxidant effects through color changes while introducing Chinese tea varieties and culture; (2) “Poetic Chemistry” for secondary/college students with chemistry background showcases metal ion reactions, extraction methods, and industrial applications to encourage scientific innovation. These home-friendly experiments combine safety and engagement while integrating traditional culture to enhance both scientific and cultural literacy.
