Rock Cycle - Class K #5

Crystals and Minerals

1.Crystals
      In crystal gorowth lab, we made a solution by mixing the minerals with water at frist. Then we waited because we needed to let the minerals to grow. The minerals became the crystal. Crystal is a solid object that has three or more sides. The color of the crystal was white. You could see through it. The luster of the crystal was non-metallic because it didn't looks like metal. The rocks are make up of mineral.

2.Mineral Properties
        Luster:
                       Metallic - Looks like metal.

                     

                       Non-metallic- Does not look like metal

  

         Streak:
                       Color- It was a color other than white or clear

                       Colorless/ White- It was white or clear

    

                    

             Hardness:
                               Soft- Does not scratch a glass plate(5.5)
The graphite rock's hardness is 1-2.
                               Hard- Scratches the glass plate(5.5)
        Quartz rock's hardness is 7.    

              Cleavage/Fracture:

        

                                               Cleavage- After it break, it's still smooth

           

                                                Fracture- After it break, it's rough
