Crystals

Crystals lab
In september we did lab about crystals. We grow crystal by using hot water, minerals, some science cups. We mixed and mixed water with minerals (adding 2 spoon minerals) till it cant take any more minerals in it. also we add food paint in it. Then after that we put our water mineral on window with open window to cool it down. After many days it grow a lot and turned to crystal.... JUst like this..

Rock types

Rock cycle is cycle of rocks... so in 2 easy words its mean rock cycle. There is three different kind of rocks (IGNEUS, METAMORPHIC, SEDIMENTARY). So first of all there is thing called magma that is melted rock. Then magma comes out from volcano and its called lava( NOT MAGMA). Then that melted rock cools down and turns to IGNEOUS ROCK, but there is two type of them "INTRUSIVE( came from inside of volcano) and EXTRUSIVE (came from outside of volcano)" IGNEOUS rock turns to Sediments by weathering and erosion ( EX: rain wind). There is 3Sediments are sand in other words. Sediments turn to Sedimentary rock by compaction and cementation( it means that god takes a paper glue and stick sand). There is 3 types of Sedimentary rocks Clastic( rock with some class in it ), Crystalline( Rock like crystal looks like sugar), Bioclastic( rock with lots of dead staff). somehow Sedimentary rock heats and pressures so turns to Metamorphic Rock. Metamorphic rocks are two different types Foliated(with layers) and Non-Foliated( with no layers). Then metamorphic rock moves far under ground and melt so turns to Magma again............................................. So that is an rock cycle-cycle of rocks

Igneous rock 

Extrusive

Intrusive

SEdimentary rock

Clastic

Crystalline

Bioclastic

Metamorphic rock

Foliated

Non-foliated

Congratulations Fellas now u know something about Rocks
