直观、具体、鲜明、形象的课堂演示实验,不仅可以生动地说明要花费许多口舌方可讲明白的理论问题,激发学生的学习兴趣和积极性,而且对高师学生以后在工作中进行演示实验教学具有抛砖引玉的作用。近年来,在有机化学教学过程中,我紧扣教材设计了一些与有机化学实验课不重复,简便易行,费时少,现象明显,可以说明一些问题的演示实验。 相似文献

The invention of air conditioner (AC) has undoubtedly saved the world from the heat of summer. The development of AC is an important embodiment of continuous development and perfection of science and technology. This article explains the mechanism of freon pollution from the perspective of chemistry, and enumerates the important role of fluoride in daily life, to eliminates people's misunderstanding of fluorine element. The hardships of extracting fluorine reflect the chemists' research experience of collecting experience from failure and the scientific spirit of pursuing the truth. 相似文献

Starting from an example of how to extinguish a fire, this article illustrates how chemical dynamics plays a role in our life. It also introduces what is chemical dynamics and the contribution of Dutch chemist Jacobus H. van't Hoff to chemical dynamics. The horse racing analogy is used to illustrate how the amount of reactants, energy, catalysts and other factors affect the chemical reaction rate. 相似文献
