What is Matter?
Matter is anything that takes up space and has
weight.
Matter has three forms.
Matter can be a solid, a liquid, or a gas.
Matter is made up of tiny particles called
molecules.
What do we know about solids?
Solids take up space
and have mass.
Solids have a shape of
their own.
Solids can be described
by their physical
properties.
Solids can be measured.
What do we know about liquids?
Liquids take up space
and have mass.
Liquids do not have a
shape of their own.
Liquids take the shape
of their container.
Liquids can be
measured (mass and
volume).
What do we know about gases?
A gas takes up space and has
mass.
A gas takes the shape of its
container.
A gas is the only kind of
matter that always fills all
the space inside a container.
The mass of a gas can be
measured.
Physical Changes in Matter
Cutting
Melting
Mixing
Freezing
Shaping
Changing from one state
of matter to another.
Evaporating
Other changes in matter
Some changes in
matter are reversible.
Some changes in
matter are
irreversible.
Rusting, burning, and
cooking are
irreversible changes.
Wonderful Water
Water can be a solid, a liquid, or a gas.
Water as a solid may be ice or snow.
Water as a liquid may be drinking water.
Water as a gas is water vapor.
Heat changes water from one form to another.
Water in all three states make up the water cycle.
