True or False: Changing
the state of matter is a
physical change.
True
When a solid
changes into a
liquid what
process is
occurring?
Melting
When a liquid
changes state
into a gas, what
process is
occurring?
Evaporation
Taylor made a lego
tower made with three
colors of legos. It weighed
5 pounds. The yellow
piece and the blue piece
both weighed 1.5 lbs. How
much did the red one weigh?
2 pounds
Ryan weighed a glue
stick and it weighed 3
lbs. The cap weighed
.5 pounds. How much
did the base weigh?
2.5 pounds
Name two
examples of
changes of state.
Melting,
freezing,
boiling,
condensing,
evaporating
What is a
physical
change?
A physical change
is a change that
does not result in a
new substance.
Give two examples of
physical changes.
Physical changes:
Ice melting, glass
breaking, wood being
chopped, paper
being cut, etc.
What are three
physical
properties
of a globe?
Physical
properties are
anything that
have to do with
the globe itself.
What is a mixture?
Give me two
examples following
the definition.
A mixture is two or more
substances being
combined without being
changed. Ex: trail mix,
salad, salt water, sand,
etc.
What is a
chemical property?
A chemical property is a
property that involves
how a substance
interacts with other
substances.
Name one
chemical property
of the element
Iron.
Iron reacts with
oxygen and water
to form rust.
What is a
chemical change?
A chemical
change is a
change that
results in one
or more new
substances.
Which state of matter
is most dense?
Solid, liquid, or gas.
The particles in a solid
are more tightly
packed than both a
liquid and a solid.
Give me three
examples of chemical
changes.
Chemical changes ex:
an egg cooking, cake
baking, fireworks,
tarnish, rust, etc.
What is density?
Density is how closely
packed the particles
are in a substance.
What are
two clues to help
you know whether
a chemical
reaction has
occurred?
Clues include a
change in color,
smell, a new physical
property is created,
there is a substance
given off, or heat.
What type of
change is
demonstrated by
each picture
shown?
What are two
experiments that we
did that demonstrated
chemical changes?
Examples will vary.
What is the
difference between
the particles that
make up a solid, a
liquid, and a gas?
The particles in a solid
are locked in place, in a
liquid they are flowing
freely, and in a gas they
are far apart and moving
quickly.
What are
the three
states of
matter?
Solid, liquid, and gas
What is the
difference
between weight and
mass?
Weight changes with
the pull of the gravity.
Mass is the amount of
matter in a substance
and never changes.
Which of the following is
a physical change?
-shredding paper
-striking a match
-iron rusting
-egg cooking
Shredding
paper is a
physical
change.
Which of the following is a
chemical change?
-breaking glass
-water evaporating
-bread baking
-wood being chopped
Bread baking is
a chemical change.
What is the definition of
matter?
Matter is anything that
has mass or takes up
space.
