Unit 1:物质的结构与性质 · Pre-AP 化学
化学的第一课不讲定义:先给学生一台「粒子模型台」,拖间距、拖有序度、拖运动速度,让固液气三态自己长出来——宏观性质是粒子层面的推论,不是需要背的名词。 Chemistry starts without definitions: students get a particle bench — drag spacing, orderliness and speed, and the three states of matter assemble themselves. Macroscopic properties become inferences from the particle level, not vocabulary to memorize.
