| Abstract |
|
This article provides a description of concrete models that represent different classifications of matter and directions for their use in the classroom. By using colored paper clips, students can represent pure substances, mixtures, elements, and compounds and then discuss their similarities and differences. This model is advantageous for the beginning student who would not know enough about the detailed composition of simple materials like milk, brass, sand, and air to classify them properly. Examples of isomers and allotropes are also created to introduce those concepts at an early stage and in an easy-to-understand format. This classroom activity would be especially suitable for a collaborative- or cooperative-learning environment, but could be adapted for individual learners.
