Properties of Matter
The student knows that matter has
physical properties and can identify
matter as liquid, solids, and gases
Matter

Made of particles and exists in one of
three main states:
solid, liquid, or gas
Matter

Can be changed from one state to
another and back by heating or cooling
So what is a solid?

Solids are usually hard because their
particles have been packed together.
Solids also can hold their own shape.

A rock will always look like a rock unless
something happens to it. The same goes
for a diamond. Even when you grind up a
solid into a powder, you will see little tiny
pieces of that solid under a microscope.
What is a liquid?

Water is a liquid.
Your blood is a
liquid. Liquids are
an in-between
state of matter.
They can be found
in between the
solid and gas
states.
Liquids will move and fill up any container.
LOOKING FOR A GAS?
Gas is everywhere.
 Gases can fill a container of any size or
shape.
 Think about a balloon. No matter what
shape you make the balloon it will be
evenly filled with the gas particles.

Gas
 The
particles in
a gas move
around the most
and are least
tightly packed.
Test your thinking!
A form of matter
that has its own
shape and
volume.
What is a
solid?
A form of matter
that has its own
volume but does not
have a shape of its
own.
What is a
liquid?
A form of matter
that has no shape
or volume of its
own.
What is a
gas?
An ice cube is water in the form of a solid. Heat makes
the ice melt.

Matter Mystery
Water was scarce in the desert, and he
trusted no one. He was horrified to
realize that he’d left his drink where it
could be stolen. But when he found his
glass, it had more water than before.
How did it get there?
