01 Water

  1. 1. Foundation Science Today’s Lesson: Water
  2. 2. Importance of WaterIf there was no water, there would be no lifeWhy is water important?1) The first life on earth came from water2) All organisms depend on water to surviveA human can live only 3 or 4 days without water!!!
  3. 3. How Much Water is There?Water covers 71% of the earth’s surfaceWhere is water found?1) Oceans 96.5%2) Groundwater 1.7%3) Glaciers 1.7%4) Lakes about 0.09%5) Vapor, clouds, precipitation 0.001%
  4. 4. How Much FRESHWATER is There?Freshwater is water without salt; the Chao Praya river isfreshwaterOnly 2.5% of the earth’s water is freshwater, the rest issaltwater from the oceans99% of the earth’s freshwater is groundwater or ice(snow), 0.3% is in lakes and rivers, and the rest is inanimals
  5. 5. THE WATER CYCLE• Water in oceans, lakes rivers or on land evaporates into the air.• It then turns into rain and falls back to the earth and the process begins again…….
  6. 6. WATER VAPOR• Water vapor is water molecules in the air• Steam and clouds are both forms of water vapor
  7. 7. EvaporationEvaporation iswhen liquidwater turns intowater vapor
  8. 8. Condensation• Water vapor turning into liquid water is called condensation• Water vapor condenses when it hits a colder object
  9. 9. Precipitation• PRECIPITATION is when water vapor turns into rain
  10. 10. THE WATER CYCLE
  11. 11. QUESTIONS (2 Points Each)1. Draw a picture showing water evaporation, condensation and precipitation.2. Is there water vapor all around you right now?3. When you have a cold drink, is it precipitation that forms on the cup, or condensation?4. Explain in your own words why water forms on the outside of a cold cup.5. Raindrops need to form on something in the air to make precipitation. What does the water vapor condense onto??
