摘要： 生活中处处充满手性之美，为了让大众正确认识手性，本文基于L-和D-酒石酸对映异构体的差异，设计实验开展科普教育：(1)酒石酸的分子模型搭建；(2)酒石酸晶体的培养与观察；(3)酒石酸溶液的旋光性观察；(4)酒石酸分子的手性拆分。科普深入浅出，实验操作简单，现象明显，互动性强，早期科普工作反响良好。

关键词: 酒石酸, 对映体, 晶体, 手性拆分, 旋光性

Abstract: Chirality permeates every aspect of life’s beauty. To foster a proper understanding of chirality among the public, this paper employs the differences between L- and D-tartaric acid enantiomers to design experiments for popularization of science: (1) Construction of molecular models of tartaric acid enantiomers; (2) Cultivation and observation of tartaric acid crystals; (3) Observation of the optical activity of tartaric acid solutions; (4) Recognition of chirality in tartaric acid molecules. These experiments range from basic to advanced, featuring simple operation, obvious phenomena, interactive communication, and have received positive feedback in the early stages of implementation.
