3. Lesson 1 – Minerals and their Characteristics
– Different Properties of Minerals
4. 1. identify the examples of minerals;
2. explain the different characteristics of minerals;
3. differentiate minerals based on their properties;
and
4. develop awareness on the importance of
minerals around us.
5. Minerals make up the rocks beneath your feet, the
soil that supports plants, and the deep rock of
Earth’s mantle.
Minerals are the building blocks of rocks.
Mineralogists use the criteria to determine
whether a material is classified as a mineral or
not.
6.
7. Graphite
Halite
magnetite., hematite, chromium
Silver, Copper, Gold, silicon
Limestone, hematite, quarts
Identify the following objects below. Then using the Internet or other possible sources,
determine what type of minerals are present in each of the presented objects in the table.
8. Arrange the jumbled letters to find
the appropriate criteria to determine
whether a material is classified as a
mineral or not.
9. - It is a product of Earth’s natural processes.
Answer:
NATURALLY OCCURING
10. - It must be product of Earth’s physical
processes.
Answer:
INORGANIC
14. 1. naturally occurring- a product of Earth’s natural
processes
2. inorganic- it must be product of Earth’s physical
processes.
3. homogeneous solid- minerals should have definite volume
and rigid shape
4. definite chemical composition—represented by a
chemical formula
5. orderly crystalline structure- atoms of minerals are
arranged in an orderly and repeating pattern
15. To identify minerals, mineralogists observe the
following properties:
a. Color .
b. Streak.
c. Hardness
d. Cleavage
e. Crystalline structure or habit
f. Diaphaneity/amount of transparency
g. Luster
h. Tenacity
16. A. Color - mineral’s
color may change
depending on the
surface.
Ex. Quartz
17. color of mineral in
powdered form.
Pyrite (FeS2)
- Exhibits the color of gold
but has a black or dark gray
streak.
20. - the external
shape of a crystal
or group of crystals
is displayed /
observed as this
crystals grow in
open space
21. - the external
shape of a crystal
or group of crystals
is displayed /
observed as this
crystals grow in
open space
22. Ability to allow light
to pass through it.
This is affected by
chemical makeup of
the mineral sample.
23. a. Metallic- generally opaque and
exhibit a resplendent shine similar
to a polished metal
b. Non-metallic- vitreous (glassy),
adamantine (brilliant/diamond
like), resinous, silky, pearly, dull
(earthy), greasy, among others
24. Brittleness- a mineral turns into powder Malleability a
mineral can be flattened by pounding with a hammer.
Ductility- A mineral can be stretched into wire.
Flexible but inelastic-Minerals are bent but they remain
in the new position.
Flexible and elastic- Minerals are bent, and they bring
back to their original position.
Sectility- ability of minerals to be sliced by a knife.
34. Controlled
variables
•These are kept
the same
throughout your
experiments
Independent
variable
•The one variable
you purposely
change and test
Dependent
variable
•The measure of
change observed
because of
independent
variable
•Decide how you
will measure the
change

Editor's Notes
This is the question that your experiment answers
Summarize your research in three to five points.
Establish hypothesis before you begin the experiment. This should be your best educated guess based on your research.
List all of the steps used in completing your experiment.
Remember to number your steps.
