2SP1. Students will investigate the properties of matter and changes that
occur in objects.
a. Identify the three common states of matter as solid, liquid, or
gas.
b. Investigate changes in objects by tearing, dissolving, melting,
squeezing, etc.

What do carrots, people, the air in
balloons, and apple juice all have in
common?
They are all
types of
matter!
• Matter is everything
around you.
• All matter takes up
space.
• Matter has mass,
which is similar to
how much something
weighs.
Matter is everything that
takes up space and has mass.
Descriptions of Matter
• Matter is described as how it:
– Looks (shiny, dull)
– Feels
– Acts
- Smells
- Sounds
• Matter is also described by it’s:
– Size
– Texture

Three States of Matter
• Matter is
categorized into
three groups called
states of matter.
– Solid
– Liquid
– Gas
Solids
• Solids have their own shape.
• Solids will remain the same shape unless
they are changed by something.
• You can touch, feel, and see solids.
• Some examples of solids include:
-Person
-Pencil
-Book
-Towel
-Banana
-Television
What solids can you name?
Liquids
• Liquids do not have their own shape.
• Liquids take the shape of the container
they are in.
– Think about when you pour juice into a cup,
the juice takes the shape of the cup.
• Some examples of liquids include:
-Water
-Juice
-Sprite
What liquids can you name?
Gases
• A gas does not have it’s own shape.
• A gas takes the shape of the container
it is in.
– Think about a time you blew up a balloon. The air that filled
the balloon is a gas. The air took the shape of the balloon.
• You can sometimes smell or feel a gas.
• Some examples of gases are:
-Steam
-Helium
-Oxygen
What gases can you name?
Let’s Compare Solids, Liquids,
and Gases
Solids

Gases
Solids have their
own shape.
A solid’s shape will
not change by
itself.
Liquids take the
shape of the
container they are
in.
Gases take the
shape of the
container they are
in.
You can see and
feel solids.
You can taste and
smell some solids.
You can taste some You can sometimes
nonpoisonous
smell gases.

You can see some
liquids.
You can feel

Solid, Liquid, Gas
Solids
Liquids
A solid's a solid,
It doesn't change shape.
It can't move around,
It stays in one place.
A liquid moves smoothly.
We say that it flows.
From one place to another-How quickly it goes!
Your desk is a solid,
And so is your chair.
Just look in your classroom-Wow! They're everywhere!
We know that most liquids
Are easy to see.
With no shape of their own,
They're not like you and me.
Gases
Air is a gas.
We can't see it, that's true;
But often we feel it
In things that we do.
It keeps up a kite.
Air fills up a bubble.
Without it to breathe,
We would be in BIG trouble!

A piece of
paper will
not
change it’s
shape.
However,
if you cut
or tear
the paper,
the shape
will
change.
Dissolving
Melting
Squeezing Freezing
Sugar is a
solid that
will not
change by
itself.
However,
when you
stir sugar
in water,
the sugar
will
dissolve.
When
some
objects
melt, such
as
chocolate
or a
candle,
the shape
will
change.
Play dough
is a solid.
You can
squeeze
play dough
to change
the shape.
Freezing
some
liquids can
turn them
into
solids.
For
example,
when you
freeze
water, the
liquid
turns to
ice.
Did you know?
• Water is the most important resource in the
world.
• Water is the only substance that exists in all
three state of matter.
• At least 75% of the Earth’s surface is covered in
water.
Earth's Water
– 97% salt water
– 3% fresh water
• Lakes, rivers,
glaciers, ice caps

• Water is a liquid.
• When water freezes, it becomes a solid called
ice or snow.
• When water is heated, it becomes a gas called
steam or water vapor.

What’s the Matter?
By Martha Ann Cole
What's the matter?
Can you guess....
It's rocks and trees and all the rest!
It's water and sky and dirt and grass,
It's everything that's in my class!
It's my brand new coat
that keeps me warm,
And all the animals
on a farm!
Matter is every single thing you see
It's everywhere around us
It's YOU and ME!
Matter takes up space and has some weight
It fills our world.....
Now ain't that great?
