Week 6 Geology Warm ups
Monday Oct 8
Objectives:
To understand the minerals
are the basic building blocks
of Earth
Today’s agenda:
• Chapter 2/3 pretest
• “Investigating crystal shape”
1. What are the four characteristics of minerals
( 2.1)
2. What is the most common group of minerals?
What percentage of Earth’s crust do they
make up?
Investigate Crystal Shape
1. Read CRYSTAL STRUCTURE and
Investigate Crystal Shape from page
46. Look at the procedure, materials
and the questions at the end. I will be
doing this lab as a demonstration.
2. Write a hypothesis for the experiment
(remember the 3 words!)
3. Identify the manipulated and
responding variables.

Tuesday Oct 9
Objectives:
To understand that minerals
are around us every day.
Today’s agenda
• Chapter 2 “diagnostic”
• Read / RSG 2.1
• Begin Chapter 2 vocab ( #s 7,
8, 9)
1. How are minerals different from rocks? Be
specific.
2. What does it MEAN to say a mineral has a
definite chemical makeup?
Chapter 2-Minerals Intro
Chapter 2
1. What do you think the most common mineral in Earth’s
crust? What are some characteristics of that mineral?

Week 6 Geology Warm ups
Wednesday Oct 10
Objectives:
To understand the properties
used to identify minerals
Today’s agenda:
• Mineral properties
notes/foldable
• Read/ RSG 2.2HMWK
• Vocab (#1,2,4,10,11,12)
HMWK
1. What is the second most common group of rock
forming minerals?
2. How are carbonates different from silicates?
• Color is the most obvious property
of a mineral; however it is also the
least reliable.
• Determine the color of a mineral by
observing the sample with the
unaided eye and noting its overall
color.
• The streak of a mineral is identified
by firmly rubbing a mineral sample
against an unglazed porcelain tile
and observing the color of its
streak.
• Determine the luster of a mineral
by observing how light reflects off
its surface.
• Looks like metal = Metallic
• Does not look like metal =
Nonmetallic
Metallic or Nonmetallic?
• Describes the way a mineral
breaks.
• If it cleaves, then it breaks along
smooth, flat surfaces.
• Describe the way a mineral breaks.
• If a mineral fractures, it breaks
along rough edges.
• Determine the hardness of a
mineral by using Moh’s hardness
scale.
• Fingernail = 2.5
• Penny (1982 or earlier) = 3.0
• Steel nail = 5.5
• Some minerals have unique
properties that enable us to
determine their identities.
• Taste
• Magnetism
• Birefringence

Week 6 Geology Warm ups
Thursday Oct 11
Objectives:
To understand how to use a
minerals properties to
identify it.
Today’s agenda:
• Finish notes/foldable
• Master Mines web activity
1. What is the difference between color and
streak?
2. EXPLAIN and GIVE AN EXAMPLE of density.
Week 6 Geology Warm ups
Friday Oct 12
Objectives:
To understand how to
identify minerals using their
properties
Today’s agenda:
Mineral identification lab
1. Why does a piece of gold weigh much more
than a piece of pyrite that is the same size?
2. What would happen if you rubbed a mineral
with a hardness value of 7 against a mineral
with a value of 5?
