A Presentation By Dr. Tatyana Simmers For NSTA
Baltimore, MD


Instructional R
ationale
:

Instructional objectives:

During this assignment students will work
in

class to identify their group of minerals and their

chemical
composition
. They will assess and report how the
y

developed.
In addition to the general

science
content

of
this
assignment, students
will utilize and fac
ilitate their

computer skills. The students will be
presenting the assignment in front of the class and defend th
eir position.

State Standards:

S8.D.1 Earth Features and Processes that Change Earth and Its Resources

S8.D.1.1 Describe constructive and destructive natural processes that form different geological
structures and resources.

Reference:
3.5.7.A, 4.4.7.B

S8
.D.1.1.1 Explain the rock cycle as changes in the solid earth and rock
types (
igneous
-
granite, basalt
,
obsidian, pumice; sedimentary
-
limestone,

sandstone,

shale,

coal; and metamorphic
-
slate,

quartzite,

marble
, gneis
s)

Content statement
:

This is a project for the mid
-
unit
assessment for

the minerals and rock cycle unit lesson
plan. The

students will have a chance to pick different group of minerals and explain its
origins, chemical

composition and

formation
of the min
eral. This assignment
will

reinforce knowledge about rock
cycle,

knowledge of different types of minerals as well as research skills’

Challenges:

In case of the library will not be available students can start their research by using books and reference
materials available in

the classroom and library with follow up visit in the computer room to complete
the project. In case of power outage students can start on a project by discussing the types of
mineral
they

will be using till the power will go back on line.

Description:


For this project you will need to pick a group of minerals from the following list and research
them.

You will need to know that is the chemical structure of this
element,

how it was formed and some
interesting fact you found out about this mineral. You will need to convince your friends in class that you
mineral is very unique and have a video about it attached to your poster .You will be presenting in front
of you class t
o convince you friends that this mineral is unique and tell something very special about it.
Please pick from the followed
list:

Mineral Classification


Minerals are naturally occurring, inorganic substances with a quantifiable
chemical composition and a
crystalline structure
. For a substance to be
classified as a mineral, it must be a solid (non
-
liquid). In addition to having a
crystal structure. The term "mineral" refers to both a material's chemical

composition, and its structure. The term "rock" should not be confused with

the term "mineral." A rock is an aggregate amalgamation of one or more
minerals, and can also contain organic substances. A rock can be composed
of only one mineral or it can contain many minerals.

Substances that are "mineral
-
like" but don't meet this de
finition are classified
as "mineraloids." Minerals range in composition from pure elements (carbon
and metals) and simple salts to highly complex silicates (emeralds,
tourmaline, etc.). According to the International Mineralogical Association,
there are cu
rrently over 4,000 known minerals, which are categorized
according to chemical composition or "mineral class." There are eight mineral
classes which are categorized by anion (negative ion) group.

This minerals shown on this
mineral classification

chart are

listed in the
approximate order of their abundance within the Earth's crust, starting with
the most abundant "silicate class."

Mineraloids Group


A "mineraloid" is a mineral
-
like substance that does not demonstrate
crystallinity

and who's chemical composition is beyond the accepted ranges
for specific minerals. Pearls contain the mineral "calcium carbonate" but the
structure is bonded together by organic materials. Obsidian is not a "crystal"
but is instead amorphous
-
glass. Amber

is a heterogeneous composite with a
"gem
-
like" appearance, but consists of resinous bodies that are soluble in
alcohol.

Non
-
Crystalline Minerals


Amber



Obsidian

Step by step :

1.

Research your mineral to find out there this mineral come from,

how it was formed, that is chemical composition and interesting
facts about your mineral.

Make sure you are convincing.
