A mineral is something that consists of Rocks, Jewels, and Gems. A mineral can only be a mineral if when you found it it was a solid. There are three different types of rocks Sedimentary, Igneous, and Metamorphic. Igneous rock forms when lava cools and hardens. Then when it gets exposed to weather weathering and erosion take charge and when they work together the break down the rocks then move the rock away from each other. 

Then in a few years of this process happening these pieces of rock turn to sediment. Then this sediment mixed with pebbles, shells, sand, and dirt becomes sedimentary rocks. The fact that these are made up of lots of different stuff makes them the rocks that you will most likely find fossils in it. Metamorphic rock is when sedimentary rocks start melting into magma but then never melt all the way.

To identify a rock or mineral there are quiet a few tests to use like color, cleavage, hardness, luster, crystal structure, density, and streak. Color defines a mineral or rocks color. Cleavage determines if the mineral or rock crumbles to little shards ( no clean cut) or into big pieces ( clean Cut). Hardness determines how hard the mineral is. Luster determines if the rock looks metallic, not metallic, dull, peril, Etc. Crystal Structure is the structure of the minerals or crystals. Density is how dens is it. Streak is what color streak does it have.

I collected data on what mineral was which when I preformed test and then put my data in a machine and identified my minerals. I did this so that I could understand the test what they were and how they would help me with figuring out my mineral, I also did this to identify the minerals that I had found on the interactive.
