Test Review
1. Describe how you find the
density of an unknown substance
and include the equipment used.

Use a Triple Beam Balance to find the
mass of an object, use a ruler to find
the volume of a rectangular or square
solid, and a graduated cylinder to find
the volume of an irregular solid.
Density equals the mass divided by
the volume
2. What is the term for the mass
per unit of volume of a
substance?
 Density
3. Describe the location of the
metals, non-metals and
metalloids on the periodic table.
 METALS
are located to the
left of the zigzag line,
METALLOIDS are touching
the zigzag line, and
NONMETALS to the right
of the zigzag line.
4. List the physical properties
used to identify metals, nonmetals and metalloids.
 density,
luster,
conductivity, malleability,
ductility, magnetic
5. Which term describes a
property of having a shiny
appearance or reflecting light?
 Luster
 Which
term describes a
property of heat or electrical
charges passing through a
material easily?
 Conductivity
 Place
the 3 main groups of
elements in order based on
greatest conductivity to least
conductivity.
 Greatest
conductivity
Metals
 Lesser conductivity
Metalloids
 Least Conductivity
Nonmetals
 You
are examining an object
in science class. It is solid, a
semi-conductor, brittle, and
is a shiny silver color.
 The
sample is MOST likely a
Metalloid
 You
are examining an object
in science class. It is a pale
yellow, brittle solid, with no
shine, and no conductivity.
 The
sample is MOST likely a
NONMETAL
 You
are examining an object
in science class. It is shiny,
malleable, and a good
conductor.
 The
sample is MOST likely a
METAL
 An
Electronic Corporation is
designing a new cell phone.
They need a solid material
that conducts electricity, and
can be made into a thin wire.
Which material would BEST
fit their needs?
 METAL
 You
need to find the density of a
cube. Each side of the cube
measures 4cm and the mass of
the cube is 12g. What is the
approximate density of the cube?
(Density=Mass/Volume)
 Round to the nearest
hundredth
 Mass=
12g
Volume= 4x4x4=64cm3
.19 g/cm3

Describe the correct way to
test a mineral’s streak
 Scratch
a mineral on the
back of an unglazed side
of a tile
 You
are testing several minerals in
science class. First, you scratched
the minerals across a tile, and then
you scratched the minerals with a
copper penny and a steel tool. What
physical properties are you testing
for?
 streak
and hardness
Reinforce Activity:
1.
Can fluorite scratch
topaz? Because…
Reinforce Activity:
2. If a mineral cannot scratch
calcite or gypsum then what
is its approximate hardness?
Reinforce Activity:
3. If a mineral cannot scratch
calcite or gypsum then what
is its approximate hardness?
 Compare
the density of a
sponge to a rock
A
rock is much more
dense than a sponge.

1. What would be the BEST title for the list?
2. What property BEST replaces the X in the
table?
 Physical
Properties
 Malleability
 Three
aluminum density cubes
compared to one aluminum
density cube will have a different
mass but the same?
 density
 What
does not change when you
cut an object into pieces?

density
 True
 Air
or False:
is not considered matter
because it does not have
mass, and is invisible.
 false
 There
are two jars that are
the same size. One is filled
with peanut butter, and the
other is filled with jelly. They
have the same volume, but
they may not have the
same……
 mass
or density
A
student has an element with a
volume of 6.7cm3 and the mass
of 75.7g. What is the density?

Mass=
75.7g
Volume= 6.7cm3
11.3 g/cm3
 During
an experiment on
density, students measure the
mass of an iron cube to be 64.5
g. They also determined that it
displaces 7.5 mL of water. What
is the density (in g/cm3) of the
iron cube.

Mass=
75.7g
Volume= 6.7cm3
8.6 g/cm3
 The
mass of a 125 cm3 piece of
material is 82.75 g. Determine
the density of this material.
 Mass=
82.75 g
Volume= 125 cm3
0.66 g/cm
 The
mass of a block is 23.9 grams
and the block displaces 8.8 mL of
water when dropped in water. What
is the density of the block?
 Mass=
23.9 g
Volume= 8.8 ml
