| streak | color of a powdered mineral |
| hardness | tells how easy to scratch a mineral |
| luster | the way light reflects off a mineral's surface |
| mineral | a natural solid substance found in the earth's crust |
| rock | a solid that is made up of one or more minerals |
| mantle | the layer just beneath the crust |
| crust | the outer layer of the earth |
| core | beneath the center of the earth |
| 3 types of rocks | Ignaceous, sedimentary,metamorphic |
| properties of rocks | luster,shape,color,smoothness,hardness and acidity |
| hardest mineral | diamond |

| 4 minerals we found in granite | feldspar, mica, hornblende,quartz |
| how mica and hornblende are alike | black and shiney differ in hardness |
| 4 tests to find out what minerals are in a rock | acid test, scratch test, color, luster,shape, streak test |
| another hardness test | scratch 2 rocks together |
| 3 properties of calcite | smooth, sharp, luster |
