Abstract

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and think critically to explore different ways for classifying and categorizing matter. This experience of analyzing traits and recognizing trends in properties provides an orientation to the periodic table’s development and organization of chemical elements. Extension options and instructional methods are provided, and are adaptable to fit teachers’ curriculum and classroom context.

摘要

元素周期表对于化学家和所有STEM专业人士而言都是宝贵的资源。但是，一开始它可能会使一些学生不知所措，并且令人生畏。本动手课程通过对简单玩具和家用物品的切实体验，向元素周期表中介绍了抽象概念。学生进行协作并进行批判性思考，以探索不同的方法来对事物进行分类和分类。这种分析特征和识别特性趋势的经验为元素周期表的发展和化学元素的组织提供了方向。提供了扩展选项和教学方法，并可以适应教师的课程和课堂环境。
