Classwork: ** NO SCHOOL
February 20, 2018:
Classroom: ** We reviewed the different ways that sedimentary rocks are formed: Clastic and Chemical and observed additional samples of sedimentary rocks not studied in class.
We read and discussed pp. 276-277 and identifyied uses for the igneous and sedimentary rocks.
We also observed and discussed sedimentary rock formations from around the United States on http://studyjams.scholastic.com
February 21, 2018:
Classroom: **We reviewed igneous and sedimentary rocks and how they are formed. We know that each of these rock types are formed in two different ways so when we started to talk about metamorphic rock today we assumed that it was also formed in to ways, IT IS!
Metamorphic rock is formed through REGIONAL (in large areas, mountain building) and Contact (the touching of magma or lava to existing rock)
Homework: **Reread pp. 278-279 and take notes.

Classroom: **Continued our discussion about the two ways that Metamorphic Rocks are formed, REGIONAL (in large areas, mountain building) and Contact (the touching of magma or lava to existing rock) and observed a Discovery Education video about Rock Formations and observe photos of everyday items that are created from rock: buildings, sculptures, Mount Rushmore/Crazy Horse, shingles on a roof.
We introduced that there are two basic types of metamorphic rocks: 1) foliated metamorphic rocks such as gneiss, phyllite, schist and slate which have a layered or banded appearance that is produced by exposure to heat and directed pressure; and, 2) non-foliated metamorphic rocks such as marble and quartzite which do not have a layered appearence.
Homework: **Reread pp. 278-279 and study rock types.
February 23, 2018:
Classwork: **We reviewed the two basic types of metamorphic rocks: foliated and nonfoliated (see above) and viewed a video that demonstratesd how the molecules of the pre-existig rock go through a change to make metamorphic rock when heat and pressure are present.
We started our Metamorphic Rock investigation lab which we will continue on Monday.
Homework: **No Homework
