You have a magnifying glass, a paint brush, a hammer, and scissors. Tell how you'd use two of these tools to find out more about a rock you find outside.
What is...
I'd use the magnifying glass to observe traits of the rock (crystal size and shape)
I'd use the paint brush to clean the rock to see hidden features
I'd use the hammer to break the rock apart to see the inside features and look at how it breaks
I'd use the pointed end of the scissors to pry small crystals or stones from the rock
I have 4 minerals:
Mineral A has a hardness of 4
Mineral B has a hardness of 5
Mineral C has a hardness of 6
Mineral D's hardness is unknown.
You scratch mineral D with mineral B and they do not scratch each other. This is what the you discover when you scratch mineral D with mineral C...
