1. Materials per student- sheet of copy paper, colored pencils, scissors, ruler

2. color streak luster cleavage & fracture density hardness
How can minerals be identified?
Draw lines every 3 ½ cm
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 i.d. minerals.
