Title
Metamorphic Rocks
I.
Problem: (Copy the question)
How are metamorphic rocks classified?
II.
Materials: (Copy the materials list as it is written on the lab sheet)
Metamorphic rock samples including gneiss, schist, slate, marble, and quartzite
III.
Procedure: (Write “see lab sheet”. Be sure to attach Student Lab Activity sheet to your report)
See Lab Sheet
IV.
Observations: (Include: descriptions, data tables, chart, drawings, diagrams, graphs)
What did you SEE?
Today we were studying how metamorphic rocks are formed and classified. In
order to observe the rocks, we recorded their origin, parent rock, and color. To find
the origin, we copied it off the introduction. To find the parent rock, we also copied
it off the introduction. To find the color, we carefully observed the rock with a
magnifying glass. To get more info, see the attached table.

Conclusions: (Restating and answering all Discussion Questions and Lab Problem in
paragraph form)
What did you LEARN?
Metamorphic rocks are classified by name, origin, parent rock, and color.
The two types of these rocks are foliated rocks and non-foliated rocks. The main
differences these types of rocks are that foliated rocks have bands or layers and
non-foliated don’t. One type of non-foliated is Marble, which is the type of rock
that fizzes with weak hydrochloric acid. This is because its parent rock is Calcite.
Marble can also be used for countertops and floors. This goes the same for Slate.
The vocabulary discussed in this lesson is parent rock, foliated, and nonfoliated. Parent rock means the original form of a metamorphic rock. Foliated rock
means metamorphic rock with bands or layers. Non-foliated means metamorphic
rock without bands or layers.
