Total questions: 15
Worksheet time: 6mins
What property is described here: Breakage of a mineral, not along planes of weakness in the crystral structure.
Cleavage
Crystal Form
Fracture
Hardness
What property is described below: Chemical interaction of hydrochloric acid and calcium carbonate (CaCO3).
Cleavage
Magnetism
Streak
Effervescense (reaction to HCl)
What mineral property is described here: Resistance to scratching or abrasion.
Color
Hardness
Luster
Specific Gravity
What mineral property is described here: Character of the light reflected by a mineral (how shiny a mineral is).
Luster
Taste
Streak
Fracture
What mineral property is described here: Visible light spectrum radiation reflected from a mineral (cannot be trusted!)
Hardness
Magnetism
Streak
Color
What mineral property is described here: Color of the mineral when it is powdered.
Effervescense
Streak
Diaphaneity
Taste
What mineral property is described here: Breakage of a mineral along planes of weakness in the crystal structure.
Color
Diaphaneity
Cleavage
Hardness
What mineral property is described here: Ratio of the mass of a mineral to the mass of an equal volume of water.
Cleavage
Color
Luster
Specific Gravity
What mineral property is described here: Electromagnetic force generated by an object or electrical field (can stick to your fridge).
Magnetism
Fracture
Luster
Fluorescence
Testing Method: Examine the mineral for areas where the mineral is broken. Look for areas where the light reflects from planar surfaces. This can be easily confused with a crystal face and is the most difficult properties for students to master.
Fracture
Crystal Form
Cleavage
Hardness
Testing Method: Look at the sample to determine if the mineral is metallic in appearance (looks like a chunk of metal) or non-metallic (doesn't look like a chunk of metal).
Color
Magnetism
Specific Gravity
Luster
Testing Method: Grind a small amount of a mineral into a powder on a porcelain streak plate and determine the color of the powder.
Color
Streak
Luster
Fracture
Testing Method: Scratch the unknown mineral with a known hardness to determine which mineral is harder. Continue doing this with harder or softer minerals from the kit until the hardness is determined.
Hardness
Effervescence (reaction to HCl)
Taste
Cleavage
Testing Method: Examine the mineral for areas where the mineral is broken. Describe the breakage as either irregular or conchoidal (has the appearance of broken glass)
Hardness
Fracture
Luster
Magnetism
Testing Method: Lick the mineral. (not recommended in an introductory lab - you don't know who has handled or licked the sample before you).
Hardness
Fracture
Taste
Streak
