Abstract Color is an important component of a colorful world. The color of thermochromic microcapsules changes with temperature, which is visual, playable and teachable. This popular science experiment focuses on the thermochromic microcapsules. Starting from the selection of molecular structure to the preparation and characterization of microcapsules, the popular science experiment explains the chemical principle behind the thermochromic phenomenon and enhances middle school students' observation and exploration of life. The experimental operation process is simple, the experimental phenomenon is close to life, and the experimental principle is easy to popularize. It can improve students' basic operation ability, transformation from theory to practice, and enhance their design and practical ability of scientific innovation exploration.
