THE WATER CYCLE By: Alison Arditi Precipitation Collection Evaporation Condensation Precipitation Collection By: Alison Arditi

Examine this glass of water…….. Can you guess how old it is?

The water in the 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. http://www.kidzone.ws/water/index.html

How is this possible????

The earth has a limited amount of water, and the water we do have is recycled again and again through what we call the………………………………………………………………………………………………………………………………………………………………………………………………………………………………………… WATER CYCLE!!

What is the water cycle?? The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above and below the surface of the Earth. Since the water cycle is truly a "cycle," there is no beginning or end. There water cycle is made up of 4 key components: Evaporation Condensation Precipitation Collection/Accumulation

EVAPORATION Evaporation is when the sun heats up water from the earth and turns it into vapor. The water vapor leaves the earth and goes into the air.

Water vapor in the air gets cold and changes back into liquid, forming clouds. CONDENSATION

PRECIPITATION Precipitation occurs when so much water has condensed that the air cannot hold it anymore.  The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.

COLLECTION/ACCUMULATION When water falls back to earth as precipitation, it then collects in the oceans, lakes or rivers or it may end up on land. The water is stored here and the cycle starts all over again! COLLECTION/ACCUMULATION

Let’s make our own model of the water cycle!?! Pick up…. 1 piece of white construction paper 1 plastic bag with materials 3 containers: 1 with dirt (D), 1 with blue rice (R), 1 with glue (G) Scissors Markers As a class lets do this together…..

THE WATER-CYCLE SONG

Little water drops that evaporated Joined up with their friends then start to fly Into a big group up in the sky And after some time goes by A cloud forms in the air Chorus Patter: Clouds (wh-wh-wh-wh-wh-wh-wh-wh-wh) Sprinkles (tap tap tap tap tap tap tap tap tap) Rain (rub rub rub rub rub rub rub rub rub) More rain (sh-sh-sh-sh-sh-sh-sh-sh-sh) Pouring (slap slap slap slap slap slap slap slap slap) Evaporation (slur-urp) Up into the sky! Chorus Chorus: First you need some precipitation which will lead to accumulation Evaporation, Condensation That's the water cycle! First the rain comes down, and the ground gets muddied But don't you frown, cause it'll be all gone soon Cause the sun and rain like you may have studied Are part of a cycle that's in play When water comes down then dries away The system is nature's way Of keeping things in tune Chorus When you see a cloud you don’t Need to hate it You can be proud you know why that cloud is there!  

Water Cycle Bracelets Everyone was given a plastic bag containing: 1 pipe cleaner 6 beads Take them out of the bag, and lets make our water cycle bracelets together.
