WHAT IS WATER?

WHAT IS WATER?. 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?.

  1. WHAT IS WATER?

  2. To BIOLOGISTS, water is the sanctuary in which life was born

  3. To GEOLOGISTS, water is a liquid earth material that makes up or comes from the earth

  4. To CHEMISTS, water is a molecule composed of 2 atoms of Hydrogen and 1 atom of Oxygen H2 + O = H2O

  5. What is WATER to YOU?

  6. Water has… No color No odor No Taste Isn’t heavy or light

  7. Where is WATER found???

  8. Water is found on ¾ of the Earth in forms such as…

  9. Ponds & Puddles

  10. RIVERS & WATERFALLS

  11. LAKES, GLACIERS, & SNOW

  12. OCEANS

  13. Oceans contain 97% of the Earth’s supply of WATER!

  14. Oceans are made of SALT WATER, the one and only environment for 1,000s of life-forms on Earth BUT…

  15. …SALT WATER will NOT support us humans! Less than 3% of the Earth’s water is fresh!

  16. WATER is unique…

  17. …It’s the ONLY material that occurs naturally on the Earth’s surface in ALL 3 states of matter:

  18. WATER can be a SOLID

  19. WATER can be LIQUID

  20. And WATER can be GAS

  21. So by now you’ve probably figured out that WATER can FREEZE, MELT, and EVAPORATE! Pretty cool, huh?

  22. Where was WATER first discovered?

  23. Modern theories consider volcanoes to be the first source of most of the Earth’s water.

  24. And guess what, WATER has to work just like you and I do!

  25. Back in the day, WATER’s job was as a waterwheel in a flowing or falling stream. This job allowed it to create rotational motion.

  26. This helped humans grind more grain, saw more lumber, and lift heavier loads better than they could by hand or with animals!

  27. Today, WATER works with gravity to turn mammoth turbines in hydroelectric power plants.

  28. So, if you are thinking WATER is really AWESOME you could grow up to be…

  29. …A HYDROLOGIST! They are scientists who study the Earth’s 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!

  30. Now, I hope all this talk about WATER didn’t just make you thirsty but also got you EXCITED to start our science unit on…

  31. …WATER!!
