摘要：

以食品调料咖喱的主要成分姜黄素为原料，通过系统优化其酸碱变色、光解、离子识别及溶剂化变色性质等，由浅入深面向社会公众及幼小群体、中学生、本科生设计了一系列科普实验。本项目从身边常见的分子入手，向公众阐述表面现象背后的化学原理，生动阐释化学源于生活、造福生活的理念，提升民众科学素养，激发探索热情。

Abstract:

In this project, curcumin, the main component of daily curry seasoning powder, was used as a raw material to design multilevel popular science experiments, by systematically optimizing its properties of acid-base discoloration, photolysis, ion recognition and solvatochromism for the general public and young kids, the middle school students, and the undergraduates. The chemical principles behind superficial phenomena were explained and uncovered to the public by the common molecules around us. Hence, the idea of chemistry originating from life and benefiting life is expounded vividly, enhancing the public's scientific literacy and stimulating their enthusiasm for exploration.

Key words: Curry, Curcumin, Color change, Performed at home, Multilevel popular science
