Mineral Structure - Cleavage and Fracture Experiment

kit #402

This engaging activity is used to help students identify minerals by their physical properties of cleavage and fracture. Mineral samples (included) are used to show cleavage in one, two, three, four, and six directions. Other minerals in the kit are used to demonstrate the conchoidal and uneven properties of fracture. This is an excellent activity to follow up crystal structure or earth chemistry units.
