The Water Cycle
Evaporation (A)
Condensation (B)
Precipitation (C)
How old is your water?
• The water in your glass may have fallen from the sky as
•
rain just last week, but the water itself has been around
pretty much as long as the earth has!
When the first fish crawled out of the ocean onto the
land, your glass of water was part of that ocean. When
the Brontosaurus walked through lakes feeding
on plants, your glass of water was part of those
lakes. When kings and princesses, knights and squires
took a drink from their wells, your glass of water was
part of those wells.
Evaporation

Evaporation is when the sun heats up water in rivers or lakes or
the ocean and turns it into vapor or steam. The water vapor or
steam leaves the river, lake or ocean and goes into the air.
Condensation
• Water vapor in the air gets cold and
changes back into liquid, forming
clouds. This is called condensation.
Condensation
Experiment

You can see the same sort of thing at home... pour a
glass of cold water on a hot day and watch what
happens. Water forms on the outside of the
glass. That water didn't somehow leak through the
glass! It actually came from the air. Water vapor in the
warm air, turns back into liquid when it touches the
cold glass.
