Chemical Make-up

Physical properties – Observable Characteristic that describes an object
Streak – Color of the powder left by a mineral
Luster – How a mineral’s Surface reflects light
Hardness – Property of mineral that relates to how much the mineral resists being scratched.

5. Other Ways to Identify Minerals
Density – Amount of Matter in a given Volume
Magnetism – Force of attraction or repulsion associated with magnets
Acid test – test that helps identify minerals containing Calcium Carbonate

6. Crystals, Cleavage, Fracture
Crystal – Solid Substance with its atoms arranged in a regular three-dimensional pattern
Cleavage – Tendency of some minerals to split along smooth, flat surfaces called planes
Fracture – Tendency of some minerals to break into pieces with uneven surfaces

7. Fracture vs. Cleavage
