Lesson Question (s)
Grade Level: 9
Physical properties of mineral and lab
How do you use minerals in your everyday life?
State Standards
and Performance
Indicators
Standard 4 Key Idea 3 Performance Indicator 3.1a: Minerals have
physical properties determined by their chemical composition and crystal
structure. Minerals can be identified by well-defined physical and
chemical properties, such as cleavage, fracture, color, density,
hardness, streak, luster, crystal shape, and reaction with acid.
Lesson Objectives
1. Students will be able to identify and describe the meaning of the
geologic terms used to describe minerals.
2. Students will be able to recognize how particular tools are used to
identify minerals. Students will be able to name the basic items of Moh’s
hardness scale because that will be the tool used in lab experiments
3.Students will be able to analyze an unknown mineral specimen
and be able to identify it. (Lab)
1. Students will complete a worksheet in class. The students will have to
match the term with the correct definition on the worksheet. (Formative)
2. Given a Moh’s hardness diagram students will list and describe the
common items used in the identification process. (Formaitve)
3. Student will complete a performance task in which they must identify
10 unknown specimens of rocks based on their physical and chemical
properties. (Summative)(Lab)

_______________
Procedure
Prior Knowledge
Students understand that earth is a dynamic system and rocks and mineral
are created from different depositional environment. Students understand
that minerals are a naturally occurring substance and often form with the
association of rocks and their environment (sedimentary, metamorphic or
igneous)
Bell Ringer
Write down 1 way in which you think you or your family use minerals
In your daily lives? Or if you don’t know just be thinking about it.
Hint: think makeup, food, electronics, household items, jewelry ect.
______________________________________________________
1. The teacher will review the bell ringer and list several way that
humans use minerals in their daily lives. This information will be viewed
on a power point presentation.
2. Teacher will lead into the today’s lesson “mineral properties and
mineral identification” Its important to know how to identify minerals so
we can find them and use them.
3. Teach mineral definition and show pictures that demonstrate that that
mineral have predictable chemical and physical compositions that are
determined on an atomic level. The students will be taking notes.
(Auditory)
4. Teach the physical properties that are used to identify minerals. These
include cleavage, fracture, color, density, hardness, streak, luster, crystal
shape and reaction with acid. Walk around the room with examples that
exhibit these properties through out the power point presentation. The
students will be taking notes. (Visual/Kinesthetic)
5. During lesson introduce the tools they will be using to ID mineral,
Mohs hardness scale. Explain the scale to students and how they will use
it in lab. Handout a copy of Moh’s hardness scale to write notes on.
Guides practice
and modeling
RBIS – Homework
and Practice (#8)
6. Have the students review these properties through guided practice.
Through out the lesson have the students divided into small groups. Hand
out a box of minerals and all the materials needed to test the minerals
properties. The teacher will use modeling and will go through each
property commonly used to ID minerals. The mineral names are known.
(Kinesthetic/Visual).
7. Teacher will have students complete worksheet in class. Students must
match mineral properties terms with definition. The teacher will go over
the worksheet in class and provide clarification for students who got
matches wrong.
8. Teacher will assign homework on Moh’s hardness scale
RBIS – Setting
objectives and
providing feedback
(Lab)
Checks for
Understanding
Lab
1. Teacher will assign students to a group, no more then 4 at each
station.
2. Students will be asked to use identification properties to identify
10 unknown minerals. Teacher will be walking around helping
students correctly identify the minerals.
3. Student will complete the lab and answer the follow up question
in class.
4. Teacher will review the follow up questions with the whole class
and clarify any confusing points.
Paraphrase- Teacher will select three student at different times during the
introduction of each mineral property to explain giving an example that
will be passed around the classroom to explain how it exhibits the
specific property being discussed.
Procedure- Teacher will look around the room during guided practice to
ensure students are correctly using the tools to ID minerals
Gestures- Review matching worksheet for comprehension in class.
Review by a show of hands how many students got the answer right.
When answers are wrong stop and research for clarification.
Procedure- During lab the teacher will walk around the classroom to
ensure students are on the right track.
Assessment
Type and purpose
(sometimes called
evaluation)
1. Students will complete a worksheet in class. The students will have to
match the term with the correct definition on the worksheet. (Formative)
2. Given a Moh’s hardness diagram students will list and describe the
common items used in the identification process as homework.
(Formative)
3. Student will complete a performance task in which they must identify
10 unknown specimens of rocks based on their physical and chemical
properties. (Summative)
Closure
Review that matter is made up of particles whose properties determine
the observable characteristics of matter and its reactivity. We use these
observable characteristics to Identify minerals which furthers determines
their use by humans. The students will write down the properties that are
important for them to recognize. These properties include cleavage,
fracture, color, density, hardness, streak, luster, and reaction with acid.
Accommodations
Materials
Computer, power point presentation slide, projector, rock and mineral
identification kits
Duration
