Identifying Minerals Lab
Objective:
To identify different minerals based on their physical properties.
Materials needed during the lab:
•
Mineral Identification Chart
•
Mohs Hardness Scale
Procedure:
1. Read through the entire procedure before beginning the lab.
2. Complete the
Purpose
and
Hypothesis
(always an if/then statement)
sections.
3. Complete
Part I
of this lab working through the lab that is in the lesson.
Make sure to have your worksheet open
so that you can record your results of each rock test.
4. Once you have identified all of the properties, click on the button to “Identify the Mineral”. Using the properties
you have identified, compare with the information provided on the Mineral Identification Chart and Mohs Hardness
scale to find the
best
match and fill in the Mineral Name column of the
Data
table.
5. For
Part II
you will also be given information about the mineral in the picture and using
only
your Mineral
Identification Chart and Mohs Hardness Scale identify the mineral in question.
6. Complete the
Observation/Analysis, Conclusion,
and
Application
sections before submitting the completed lab
exercise.
Purpose:
Refer to the objective of this lab to write a 1-2 sentence purpose statement for this lab. What do you want the
outcome to be? What question(s) are you trying to answer?
(5 pts)
Hypothesis:
If you are able to correctly identify the physical properties of the minerals, what will be the result?
Remember to always write it as an if/then statement.
(5 pts)
Part I:
C
omplete the data chart
on the next page
based on the physical properties you are able to identify from the mineral
identification chart, Mohs Hardness scale, and the interactive website.
(0.5 pts per blank / Mineral Name 1 pt each))
(Hint: Any luster other than “metallic” will fall under the “nonmetallic” sections of the Mineral Identification Chart”)

Part II: Who Am I?
Directions:
For this section of the lab, you will be given an image of a mineral and a few of its properties. Using the
information provided along with the mineral identification chart and Mohs hardness scale, you will need to determine
the name of the mineral.

•
I have a white streak.

I can
't
be scratched by
a
knife, but I’m harder
than a penny.
•
I fracture when broken
along four planes.

I have a vitreous

My streak is
colorless.
•
I’m
as hard as
gypsum
.
•
My mineral name
sounds similar to my
mineral color

•
My streak is so dark it
sometimes looks black
•
I have a greasy,
metallic luster
•
I’m as hard as a pocket
knife and a steel nail
•
I’m often used in
writing utensils

•
Talc is one mineral that
is softer than me (and
there aren’t many!).
•
When broken, I don’t
break along any flat
surfaces.
•
My streak is the same
as my typical mineral
color

Observation and Analysis:
In this lab, you looked at a number of different physical properties for each mineral in order
to identify the sample on display. Why was it necessary to consider more than just one or two physical properties in
order to identify each mineral? What properties were most beneficial to you in identifying the minerals whose names
were not provided? Why?
Write 3-5 sentences answering these questions
.
(10 pts)
Conclusions: Write 3-5 sentences
with your conclusions to this lab exercise. In your response, consider the following
questions: What did you learn from this lab exercise? Was your hypothesis correct? What are some ways this
experiment could be improved? What other properties of these minerals would have been helpful information for you
to have in naming some of these minerals?
(10 pts)
Application:
Take a moment to praise the Lord for creating all of the beautiful and unique minerals you looked at today
(and many more!). Thank Him for giving humans the ability to use these resources to create things we use every day like
jewelry, salt, artwork, home furnishings, etc
.
Write 1-2 sentences
about why you are thankful for one of the minerals
you looked at today.
