To BIOLOGISTS, water is the sanctuary in which life was born To GEOLOGISTS, water is a liquid earth material that makes up or comes from the earth To CHEMISTS, water is a molecule composed of 2 atoms of Hydrogen and 1 atom of Oxygen H 2 + O = H 2 O What is WATER to YOU? Water has No color No odor No Taste Isnt heavy or light Where is WATER found??? Water is found on of the Earth in forms such as Ponds & Puddles RIVERS & WATERFALLS LAKES, GLACIERS, & SNOW OCEANS Oceans contain 97% of the Earths supply of WATER! Oceans are made of SALT WATER, the one and only environment for 1,000s of life-forms on Earth BUT SALT WATER will NOT support us humans! Less than 3% of the Earths water is fresh! WATER is unique Its the ONLY material that occurs naturally on the Earths surface in ALL 3 states of matter: WATER can be a SOLID WATER can be LIQUID And WATER can be GAS So by now youve probably figured out that WATER can FREEZE, MELT, and EVAPORATE! Pretty cool, huh? Where was WATER first discovered? Modern theories consider volcanoes to be the first source of most of the Earths water. And guess what, WATER has to work just like you and I do! Back in the day, WATERs job was as a waterwheel in a flowing or falling stream. This job allowed it to create rotational motion. This helped humans grind more grain, saw more lumber, and lift heavier loads better than they could by hand or with animals! Today, WATER works with gravity to turn mammoth turbines in hydroelectric power plants. So, if you are thinking WATER is really AWESOME you could grow up to be A HYDROLOGIST! They are scientists who study the Earths water supply. Their job is to inform management about strategies that will help provide an adequate supply of water for the future. Sounds like a pretty cool career to me! Now, I hope all this talk about WATER didnt just make you thirsty but also got you EXCITED to start our science unit on WATER!!
