Standard 3b. When liquid water
evaporates, it turns into water vapor in the air and can reappear as a liquid
when cooled or as a solid if cooled below the freezing point of water.
Standard 3c. Water vapor in
the air moves from one place to another and can form fog or clouds, which are
tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or
1. Review of Wind
Last week you learned about wind
and convection currents.
When two currents
come together, it makes wind. If one current is very cold and
the other current is very hot what happens?
It creates a very gentle breeze.
It creates a mild wind.
It creates a very strong wind
of these is true?
Colder air rises up and warm air sinks down.
Warm air rises up and
colder air sinks down.
2. How old is your water?
Did you know that
the water that comes out of our water fountains is the same water that
dinosaurs splashed in as they waded through lakes and rivers. How
is that possible?

3. What is a cloud?
cloud is made of tiny water droplets (or
ice crystals) that are in the air. If the droplets become large
enough, they may be visible as a cloud or

Water Vapor from evaporation
This is similar to the way you separated salt from water.
Do you remember this?
This is a mini
water cycle that you can make.
Where is all the water?
you know how Earth's water goes in a circle from
liquid to gas back
to liquid again. Water is in the air, in rivers and lakes,
oceans and as a solid in glaciers. Click to
look at this. Where is most of the Earth's water?
rivers and lakes
This graph shows where all
of the Earth's water can be found. There's not much for us
1% of all Earth's water is drinkable.
2% is frozen in
The other 97% is found in
