Requires: two regular balloons, shape balloons and a balloon pump (optional), a liquid measuring cup, a clear cup, water, a tall and thin, and a short and wide container, a freezer (home assignment), marker or crayon Defines matter and explores the characteristics of the states of matter: solid, liquid, gas and plasma
You will also need
a clean flat area to do the projects:
The air you breathe,
the water you drink,
are all made of SOMETHING.
That something is called- -
Matter rhymes with
Matter can be a SOLID--
hard or soft, cold or hot,
rough or smooth, heavy or light.
A solid is unchanging in shape and volume.
Pick out each item below that is a SOLID.
Can you name SOLID objects near you?
Can you think of other LIQUIDS?
Matter can be a LIQUID,
wet and flowing,
with no fixed shape of its own.
Let’s play with a liquid -- WATER.
Squeeze it into
a balloon with water.
A liquid has no shape of its own.
Like the water in the balloon,
a liquid takes the shape of its container.
Look at the shape of the liquid in . . .
A liquid takes the shape of its container.
or a hole in the ground

Let’s measure the volume of a liquid --
the space it occupies.
Measure another cup
Pour it into a short,
EVEN though one is tall and thin
and the other is short and wide,
THEY BOTH HAVE THE SAME AMOUNT: 1 CUP.
A cup is a cup is a cup.
has more water
Pour it into a
TALL glass or jar.
Measure one cup
a liquid takes up
the same space or volume,
NO matter where you pour it.
Tall or short,
contained or flowing...
Matter can be a gas.
AIR! AIR! AIR!
Air is made of gases.
You breathe air.
You use air to make
other gases all the time.
You must take in
oxygen (O2) gas.
methane - CH4.
You breathe out
carbon dioxide (CO2).
WATCH as an adult SLOWLY blows up
NO! The air (gases) spreads throughout
Click for answer.
Does air go to the bottom
of the ballon, as the water did
How does air fill a container?
Can you twist
into many shapes? WHY
A GAS has no definite shape or volume.
Leave room at the end.
What SHAPE does a gas have?
Let’s find out.
Use a pump to fill the long thin balloon with air.

STATES of matter . . .
Now you know about THREE
Can water or other matter
be in MORE than ONE of these
Click for answer.
Wait overnight or
at least a few hours.
Let’s change water from a liquid to a solid.
Find these items.
Pour water or juice into a cup. Mark the height
with a permanent marker or crayon.
You used the freezer to change
liquid (mostly water) into solid ice!
It is bigger.
What do you think will happen if you fill a glass jar
or plastic container with water, seal it with a lid or cap and put it in the freezer
The glass may break as the water expands as it freezes!
The plastic tends to stretch.
Is the height
of the ice different from the marked height of water
You changed the STATE of water.
Matter can be in all three states.
be solid ice.
Water can be a liquid.
be a gas, a vapor.
States of Matter
Lightning, neon signs and plasma balls generate plasma.
Plasma is a fourth state of matter.
In fact, perhaps 99.999%
of the matter in the observable universe is
The matter inside
our own SUN
is neither a solid,
a liquid or a gas.
It is PLASMA!
Plasma particles are
and extremely energetic.
Recently, OTHER states of matter,
none of which are observed
under normal conditions here on Earth,
have been found.
Let's save these for another day!
