Which question would help you classify minerals by luster?

• what color is it?

• Does the mineral shine when you put light on it?

• can it be scratched?

• what does it feel like?

You have two minerals in your hand. One has a hardness of 4 and one has a hardness of 5. They are the same color texture and luster, and you need to figure out which is which. What could you do?

• Scratch the minerals against one another to figure out which is harder

• Feel which is rougher because that tells us the hardness.

• Determine which is shinier because that will tell us which is harder.
