摘要: 构建了一个自制的简易糖-光实验平台,通过对检偏偏振片进行特殊设计,可以获得剪纸艺术作品以及变色七巧虹板。此外,将中间的糖溶液改为糖积木,还可以得到霓色积木。这一方法装置简便、操作简易、原理明了,充分满足了科普活动对操作安全性、灵活性以及展示趣味性和生动性的要求。在颜色的变幻之中,让学生亲自动手探究光与旋光性分子相互作用的奥秘,从而理解物理化学之美。

Abstract: We have developed a homemade sugar-based light experimental platform by specially designing an optical analyzer, allowing us to observe paper-cut art and dynamic rainbow boards. Moreover, by substituting the central sugar solution with sugar building blocks, we can create neon-colored building blocks. This apparatus is easy to set up and operate, with a clear and concise principle, meeting the requirements of popular science activities for safety, flexibility, and engaging demonstrations. Through observing the shifting colors, students can personally delve into the mysteries of the interaction between light and optically active molecules, thereby enhancing their appreciation of the beauty of physical chemistry.

Key words: Optical properties of sugar, Optical rotatory dispersion, Polaroids, Science popularization of chemistry
