Laboratory Activities – Lab
#2
By: Carlin Conk
Lab Activity #1
Investigating Rocks and Minerals
Lab Activity #1 Objectives
• Examine the rock and mineral specimens using
the internet links provided or the PowerPoint file
for Lab #2.
• Note differences in color, shape, and size of
minerals.
• With the rock samples notice the differences
between the three broad classes of rocks:
igneous, metamorphic, and sedimentary.
• Note the size and arrangement of individual
minerals.
• As you look at the rocks and minerals, complete
Tables 1 and 2.
Lab Activity #1 – Table 1
• Quartz is the first mineral that we need to
examine in Table 1.
• You can use the PowerPoint file listed for
Lab #2 and scroll through until you find
“Quartz” listed under the “Primary Mineral”
section.
• What is the color? White?
Lab Activity #1 – Table 1
• Now we need to determine the plant
nutrients associated with quartz minerals.
• We can easily complete this task by
looking at the chemical formula for quartz.
• The chemical formula for quartz is Si02.
• Since neither silica or oxygen is a plant
nutrient, we would say “none” under the
“Plant Nutrient” category.

Lab Activity #1 – Table 2
• Granite is the first important soil forming
rock that we need to examine.
• We need to first determine the class that
granite belongs to.
• We can go back to the PowerPoint for Lab
#2 and search for ‘granite’.
• We find that granite is the first rock listed
with the igneous rocks.
Lab Activity #1 – Table 2
• We then need to find the dominant
minerals associated with granite.
• In the PowerPoint file and also in the
laboratory hand-out, we see that granite is
composed of quartz and orthoclase
feldspar.

Lab Activity #2
Rock Cycle Model
Lab Activity #2
• We must investigate the rock cycle model
and note the processes (such as: heat,
pressure, erosion, etc.) that change one
rock class to another.
• Then, we will answer questions using the
rock cycle as a guide.
Lab Activity #2
• You should use the
hyperlink, “Rock Cycle
Model”, to answer the
questions.
• Click on the rock type that
you would like to
investigate for a
description.
Lab Activity #3
Geology of North Carolina
Lab Activity #3
• In this exercise, we will be investigating
the geology of North Carolina using a
geologic map.
• Finally, we will answer the 2 questions.
Lab Activity #3
• Use the hyperlink provided in the instructions to
familiarize with the rock types of North Carolina.
• Click on the area of the map that you would like to
investigate further.
• For example, if you wanted to investigate the Coastal
Plain, you would click on the yellow section.
