Lab Test

 

The lab test will be on Friday, 16 November 2018.  Students with last names beginning with the letters A to K will show up for the lab test on Friday at 12:45 PM.  Students with last names beginning with the letters M to Z will show up for the lab test on Friday at 1:15 PM.

 

The lab test will have 14 stations.  You will have 1 minute at each station.  Some stations have 1 question (an identification question).  Some may have 2 or 3 questions (see examples below).  You may return to any station after the main part of the test.

 

All minerals & igneous rocks & sedimentary rocks & metamorphic rock present in the study set on reserve in the library (Warner Center, OSU-Newark campus) are fair game for lab test questions.

 

The complete study set consists of TWO trays of specimens (see list below).  Each specimen is labeled.  Please try not to mix up samples & labels.  I will check on the study sets periodically to ensure that samples and labels correspond correctly.

 

Photographs and descriptions for all 3 groups of rocks that are fair game for lab test questions are available at my geology website and my flickr website - Igneous, Sedimentary, Metamorphic.  Common minerals are here.  Labeled photos for the minerals are here.

 

 


 

Example Lab Test Questions:

Identify this mineral.

 

Identify this rock.

 

Identify this rock.  Is this rock felsic or mafic?

 

Identify this rock.  What is the texture of this rock? (options: crystalline, clastic, foliated, glassy, vesicular/frothy)

 

Identify this sedimentary rock.  Is it siliciclastic, biogenic, or chemical?

 

Identify this mineral.  How many different cleavage planes does it have? (options: 0, 1, 2, 3, 4, 6)

 

Identify the pink mineral in this rock.
