Classifying Matter—A “Nuts and Bolts” Demonstration Kit

Product Details

The perfect introductory activity to teach elements, compounds and mixtures! What does an element look like? How is an element different from a compound? Bulk samples of an element, a compound and a mixture may look similar. When we ask students to classify matter using these concepts, we want them to see what they look like “on the inside”—to imagine atoms and molecules. Use this “nuts-and-bolts” demonstration to help students visualize abstract concepts relating to the classification of matter. Your students will be more successful in learning chemistry as they build visual connections between the real world and that of atoms and molecules. Teacher Demonstration Notes provided.

Concepts: Elements, compounds, mixtures, classification of matter.
Time Required: 20 minutes
