history and
structure
geologist
•a person who
studies the Earth
and the materials
of which it is made
property
•is something you
can observe, such
as size, color,
shape, and texture.
diameter
•is the distance
across a
circular object
circumference

around a
circular object

mass
weigh
•using a balance
to determine the
objects mass

•a body of matter
stuck together to
form an indefinite
shape often of
considerable size
Content/Inquiry
• 1.) What properties can help us tell one
rock from another?
• 2.)How can you tell your mock rock
from another mock rock or a real rock?
• 3.) Why do geologists try to look
carefully at the different properties?
• 4.) How can we make comparisons of
the different sizes of rocks?
rock
•is an earth material
made up of different
ingredients called
minerals
•
Investigation 1 part2
mineral
•is an ingredient of
rocks that cannot
be broken down
any further
dissolved
• when some substances
mix with water, they
break down into such
small pieces that they
seem to disappear into
the water
Content/Inquiry
• 1.) What is the difference
between rocks and
minerals?
• 2.) How can the minerals
in a rock be separated?
crystal
•is the solid form of a
material that can be
identified by its
shape or pattern
•
Investigation 1 Part 3
evaporate
•when water is left
open to the air it
changes in gas
form
Content/Inquiry
• 1.) How were you able to
separate the salt from
the water?
• 2.) How did you know
that the square crystals
were salt?
Content/Inquiry
• 1. What is a mineral?
• 2. What is the difference between a rock
and a mineral?
• 3. If someone sent you a letter and said
they needed your help to identify a mineral
that they had found, and they told you it
was about the size of your fist, would you
be able to identify it? Why or Why not?
•
Investigation 2 Part 1
Content/Inquiry
• 1.) What do we mean when we
say a mineral has a certain
hardness?
• 2.) If you didn’t have any tools,
how could you learn if one
mineral was harder than another?
•
Investigation 2 Part 2
Rocks worked with
•Basalt
•Limestone
•Marble
•Sandstone
•
Investigation 3 Part 1
Content/Inquiry
•1.) Why are we
testing for calcite in
several rocks?
•2.) Why use vinegar
to test calcite?
Evidence
•Signs or facts on
which a
conclusion can
be based
.
Investigation 3 part 2
Content/Inquiry
• 1.) Why did we have to do
two tests before we could
decide which rocks
contained calcite?
• 2.) Why did we evaporate
the liquid in the second
test?
Content/Inquiry
•1.) What minerals
make up granite?
