Warm Up On your notebook paper, write down as many vocabulary, phrases, or pictures that relate to the Water Cycle.
Riddle ** Can weigh 8,340 pounds? Is directly delivered to your home? When in short supply is more valuable than gold or diamonds? You have to consume it to live, but if you consume too much you can die. Is our most precious natural resource? Makes all life possible? Can be found in a gas, solid or liquid form? Is so pure you drink some of it?
Water Created by: Ms. Loe
Did you know??? The earth is called the water planet because 70% of Earth’s surface is covered by water Of all the water found on Earth, only 3% is fresh water; the rest (roughly 97%) is salt water Less than 1% is useable by humans
Fresh Water is Everywhere! Rivers and Lakes (0.3% of fresh water) Ice – icebergs (76% of fresh water) Below Earth’s surface – ground water, or water that fills all the cracks and spaces underground (3% of fresh water) Water Vapor (0.03% of fresh water)
Do you want to see something amazing?! The water I have in this beaker is ancient water. This water quenched the thirst of a glossopteris fern millions of years ago. Later it became brontosaurus pee, until it evaporated into the atmosphere. It then floated around for a while as a cloud high in the sky. Later, it fell down as rain over Paris, France. It eventually made its way to America where it floated down the Colorado River passing great sights such as the Grand Canyon. Then, it made its way to Mr. G’s house – to his toilet. He strained & grunted & groaned . . . until finally, he dropped the big one - #2 and flushed it away. Finally, the water made it’s way to DMS – the lime hall water fountain where you drank it . . . and I put it into this beaker.
Water Goes Through a Cycle All water is recycled. Water is recycled through the water cycle The water cycle is the continuous process by which water moves through the living and non-living parts of the environment. In the water cycle, water moves from bodies of water, land, and living things on Earth’s surface to the atmosphere and back to the Earth’s surface
The Driving Force The most important factor that drives the water cycle is the sun!
Water is always moving! Because water is continuously moving through the water cycle is has no beginning and no end!
Step 1: Evaporation – when liquid absorbs enough energy it becomes a gas called water vapor. Even salt water becomes fresh through evaporation. HOW! – As water evaporates the salt is to heavy to evaporate so the salt stays. Water evaporates from: Oceans Rivers/lakes Soil Puddles Your skin When plants sweat they give off a water vapor. This process is called transpiration

Step 2 Condensation The water vapor rises upward. The higher up you go in the atmosphere the cooler the air gets, and the molecules begin to cool down and condense/form back into tiny liquid water droplets.
Condensation Tiny condensed water droplets clump around dust particles in the air and a cloud is formed. Dust Water droplet Clouds
Step 3 Precipitation- As more water vapors condense into liquid water droplets, the water droplets eventually become too heavy and they fall back to Earth as precipitation.
Back to Step 1… The precipitation falls to land and then begins to evaporate, thus starting the water cycle over again. Try This
