Building and using molecular models puts into action chemical language and concepts, as well as concepts from other disciplines, such as mathematics. It is an important didactic activity for understanding and exchanging meanings about fundamental concepts in basic and advanced chemistry topics. The models described here help students understand molecular representation, which is abstract and difficult to imagine and draw, and then integrate it with chemical situations and knowledge. On the basis of our experience with students, particularly in a class of 44 students, inviting them to build their own molecular models is an activity that promotes their participation in class and the laboratory. We provide details regarding how to use inexpensive plastic drinking straws for assembly; they cost very little and enable analogue models that express connectivity in molecular structures to be built, a strategy that enhances understanding of the spatial organization and characteristics of molecules, as well as that of molecular thought for solving chemical problems.

建立模型！使用塑料吸管的化学语言和分子模型的建立

建立和使用分子模型会将化学语言和概念以及其他学科（例如数学）的概念付诸实践。这是一项重要的教学活动，用于理解和交换基本和高级化学主题中基本概念的含义。这里描述的模型可以帮助学生理解分子表示法，它是抽象的并且难以想象和绘制，然后将其与化学状态和知识相结合。根据我们在学生中的经验，特别是在44名学生的课堂中，邀请他们建立自己的分子模型是一项旨在促进他们参与课堂和实验室活动的活动。我们提供有关如何使用便宜的塑料吸管进行组装的详细信息；
