1g. properties of solid, liquid, and gaseous substances, such as sugar
(C6H12O6), water (H2O) helium (He), oxygen (O2), nitrogen (N2),and carbon
What is Matter?
Look around the classroom. Everything, from the
clothes you are wearing to the air you breath is matter.
Matter is very important. Matter makes up everything including living
things like plants and people. It also makes non-living things such as
tables and chairs. Things as big as
an elephant or as tiny as a grain of sand on a beach are matter.
Everything is matter and matter comes in three different
liquid and gas.
That means that everything is either a solid, a liquid, or a gas. Each state has

has properties, but what does that mean?
A property describes how an object
looks, feels, or acts. So that means that
liquids look, act, or feel differently than
solids or gases.
of all matter,
whether it's a solid, liquid, or
gas, is that it takes up space and has mass.
To help you
decide if something is a solid, a
liquid or a gas, you need to know the
properties, (how it looks, acts or feels) of these three states.
3. What are the properties of
1. Solidsdon't change
Think of a
piece of paper, you can change its shape by crumpling it, but it
doesn't change its shape by itself. You have to use your energy to
make the shape change.
If you put a solid in a container it won't change its shape...
No matter how much you move or slide it around.
Think of an ice cube inside a cup. The cube is solid and it stays
the same shape.
are in an aligned array.Look at the pictures. Notice the
circles (particles) are lined up in tight rows. They are
so tight they can't move, they just wiggle.
4. What are the properties of liquids?
take the shape of their container. If
you pour milk into a glass it will take the shape of the glass. If
you pour the milk into a bowl, it takes the shape of the bowl.
2. Liquids have
The particles hold on to each other, like holding hands with a friend. The skin or surface of a
glass filled with water holds together because the particles hold one to
each other. That is called
The particles in liquids are farther apart than those of solids, so they
can move around more.
That's why liquids take the shape of their container.
is invisible. That means you can't see it. The
particles are so far apart they are invisible, but they are still there! Think
about oxygen. You can't see it, but you know it's there because
you breath it.
particles move around freely. They are spread out
move fast, like when you are running on the playground at
