1. On slide 2, have students count lines on their paper before drawing the lines. Some may need to draw a line every 3 lines instead to make the 7 sections.

2. color streak luster cleavage & fracture density hardness
How can minerals be identified?
color
streak
Now cut along each line (top sheet only!)
luster
cleavage & fracture
density
hardness
special properties

3. How can minerals be identified?
They’re both quartz!
one mineral can come in different colors
and different minerals can be same color
impure quartz= orange/pink
pure quartz=clear
so color is not a good way to id minerals
streak
luster
cleavage & fracture

4. How can minerals be identified?

streak is the color of the mineral’s powder
mineral
it’s found by dragging the mineral against a streak plate
