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

mass
weigh
•using a balance
to determine the
objects mass
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?
