States of Matter
(Phases of Water)
• I can describe the movement and draw
the molecular structure of liquid water,
solid water (ice), and water vapor (gas).
• I can describe why water changes from
one state of matter to another.
State of Matter:
Brain pop Video
During the video, fill in the chart.
• H20 phase (example: what is water called
when it is a solid?)
• Structure: Volume/Shape
• Draw a picture of H20 molecules in a
liquid, gas, and solid (in that order)
– Act it out!

Water Molecules
Water is made up of
molecules . Water
changes state (gas,
liquid, solid) when it’s
molecules are heated or
cooled.
Molecules
Water molecules become less
dense when heat is added. This
happens when water changes from
ice to liquid or from liquid to gas.
Add Heat
Add Cold
Water molecules become dense
when in cold temperatures. This
is seen when water turns to ice
or changes from a gas to liquid.
For each arrow, write if heating or cooling is
occurring, and what the process is called.
Heating: Boiling/
Vaporization
Heating: Melting

Cooling: Condensation

Cooling: Freezing
What is happening to the molecules?

• What you think the
molecules look like
at each stage of the
water cycle.
• How does the sun
affect the water on
Earth?
