Abstract

In this Activity, students use their deductive reasoning skills as they identify formulas of unknown elements and compounds modeled by paperclips. Each color of paperclip represents a different element, with linkages between different paperclips in appropriate ratios representing 20 unknowns. The Activity supports formation of a basic understanding of elements and compounds, including allotropes, oxidation states, and diatomic elements.
