Abstract:

以核心素养为导向开展实验教学,以“人类血液中首次发现微塑料”为情境主线,创新性地用淀粉为来源合成可降解生物塑料,并引导学生通过分组实验探究得出影响淀粉基可降解生物塑料性能的因素。实验用品廉价易得,实验创新性强、趣味性强、可操作性强、可推广性强,为高中化学可降解高分子的实验教学提供参考。
Carrying out experimental teaching oriented by core competencies, with the situational theme of “microplastics first discovered in human blood”, this innovative approach synthesizes biodegradable bioplastics from starch and guides students through group experiments to explore and identify factors influencing the performance of starch-based biodegradable bioplastics. The experimental materials are inexpensive and easily obtainable, while the experiment itself is highly innovative, engaging, operable, and scalable, providing a reference for high school chemistry experimental teaching on biodegradable polymers.
