Summary

We grew Crystals in our Earth Science class and learned about different Minerals. First we get a beaker and we put hot water until the water get to 100 ml. Then we started to pour the Minerals in order to grow Crystals. We Stir the minerals until the mineral Saturated. After this we put the mineral near the window so it will get sunshine and wind because it need Cool Evaporation for Solidification. Then we wait for few days to get our crystals. We grew three types of crystals which are: Halite, Sucrose, and Epsomite.

Mineral Properties

LUSTER:  Metallic and Non-Metallic

       
            METALLIC                                 NON-METALLIC

 COLOR: color of minerals

 
     Different color rocks

Streak: Powder of the minerals


     

Hardness: How much hard is the mineral:

 

Cleavage: When the mineral breaks evenly.



Fracture: When the mineral breaks unevenly.




Composition: Chemical of the minerals.



Other Properties: Any other thing define the mineral.
