1. The Water Cycle Evaporation (A) Condensation (B) Precipitation (C)

2. 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.

3. 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.

4. Condensation • Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.

5. 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.
