Metamorphic Rock Identification

In this activity students develop skill in the visual identification of metamorphic rock species and conceptualize the relationships between non-metamorphosed species and their metamorphic counterparts. Students will use a hand lens to examine metamorphic rocks and make observations about grain size, foliation, and other characteristics. Then, using this data, they identify the rocks with the classification sheet included with the student worksheet. They will then match the metamorphic rock with its parent rock.
