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.
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
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
How can minerals be identified? color streak is the color of the mineral’s powder mineral it’s found by dragging the mineral against a streak plate streak plate streak luster cleavage & fracture
