化学是一门以实验为基础的科学,通过化学实验教学可以大大激发学生学习化学的兴趣,尤其是那些火花四射、烟雾升腾的魔术般的趣味化学实验,对中学生更有巨大的诱惑力。本文简要介绍设计趣味化学实验的一般原则和方法,仅供参考。 1 根据化学反应物质颜色的变化设计 很多趣味化学实验都是根据发生化学反应 Chemistry is an experiment-based science. Through chemical experiment teaching, students’ interest in learning chemistry can be greatly stimulated. In particular, those magical and interesting chemistry experiments with sparks and smoke rising are more attractive to middle school students. This article briefly introduces the general principles and methods for designing fun chemistry experiments for reference only. 1 According to the changes in the color of chemical reactants, many interesting chemical experiments are based on the occurrence of chemical reactions.
