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.
