An activity of using waste plastic caps and wooden sticks (or steel wires) to construct crystal structures is described. Caps with different colors represent different atoms/ions/interstices, and sticks are employed to carry the caps and describe the positions of atoms/ions/interstices. The cap-and-stick model clearly demonstrates crystal structure characteristics from multiple viewpoints. Students have participated in this activity, and their feedback suggests that the activity is helpful in deepening their comprehensions of lattice structures, unit cells, packing arrangements, distribution and filling of vacancies, and coordinates of atoms/ions/interstices and cultivating hands-on ability and a spirit of teamwork.

重复利用废塑料盖来构建廉价且易于更改的晶体结构模型

描述了一种利用废旧塑料盖和木棍（或钢丝）构建晶体结构的活动。不同颜色的帽子代表不同的原子/离子/间隙，并用棍子来承载帽子并描述原子/离子/间隙的位置。帽棒模型从多个角度清楚地展示了晶体结构特征。学生参与了本次活动，反馈认为本次活动有助于加深对晶格结构、晶胞、堆积排列、空位分布与填充、原子/离子/间隙坐标等的理解，培养动手能力和团队合作精神。
