基于热致变色微胶囊的科普实验方案
Popular Science Experiment Scheme Based on Thermochromic Microcapsules
【摘要】 颜色是缤纷世界的重要组成部分,热致变色微胶囊的颜色随温度变化而变化,具有“可视、可玩、可教”的特点。本科普实验以热致变色微胶囊制备为切入点,从分子结构选择到微胶囊制备和表征,讲述热致变色现象中的化学原理,提高中学生对生活现象的观察力和探知力。本实验操作过程简单、实验现象贴近生活、实验原理易于推广,可以培养学生的基础操作能力,有利于提高学生从理论到实践的转换水平,提升科创探索的设计和动手能力。
【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.
