2) Explain to students the reasons why the streak color of a mineral may be different from the color of the mineral itself. Have students research how streak can be used to distinguish gold from iron pyrite. 

Have students use the Mohs scale to give ranges for a mineral that can be scratched by your fingernail, a mineral that cannot scratch glass, and a mineral that can scratch glass.
