Watercycle

  1. 1. Contents Introduction The Water Cycle Movie Assignment Core Curriculum Work Cited Links
  2. 2. Sun Click the words on the picture to learn more CondensationPrecipitation Evaporation Bodies of Water
  3. 3. The Sun-The sun warms the Earth’ssurface and heats it.-When the water is heated itturns to a vapor and rises.-The sun is the source ofenergy that drives the watercycle.
  4. 4. Evaporation- Evaporation is the process in which water is turned from a liquid to a vapor.- Heat is the energy that breaks the bond of water molecules so they can rise.- Evaporation from the ocean makes up 80% of precipitation.
  5. 5. Water Vapor- Water vapor is water in the form of gas.- Forms of vapor: clouds, steam, and fog.
  6. 6. Condensation- Condensation is the opposite of evaporation.- Condensation is the process in which vapor is turned back into a liquid.- The water particles rise and form clouds.
  7. 7. Precipitation- Precipitation is caused once water particles in clouds get so heavy the fall.- Precipitation is the produce of condensation.- Forms of precipitation: rain, snow, hail, sleet, graupel , and drizzle.
  8. 8. Forms of Precipitation-Rain-Snow-Hail-Sleet-Graupel-Drizzle
  9. 9. Infiltration- Infiltration is the process in which water on the ground enters the soil.- The water moves underground between rock and soil.
  10. 10. Bodies of Water- The amount of water on Earth is always the same.- 97% of water is in oceans.- 2.4% of water is frozen in glaciers.- .5% of water is groundwater.- .01% of water is in lakes and rivers.- Only 3% of water on Earth is fresh water.
  11. 11. Groundwater- Groundwater is water under the ground in the soil and rock fractures.- Groundwater is also called an aquifer.- Groundwater can flow to meet other bodies of water like rivers or lakes.

Assignment Materials TasksPartner Trace a puddle with chalk, repeat every 20Clock minutes and record the temperature.Thermometer Measure the space betweenChalk the chalk lines with the ruler and record in journal.Ruler Create a graph display your findings and upload it to aJournal Wikispace and tell what you learned.
  14. 14. Core Curriculum4th grade ScienceStandard #1- Students will understand thatwater changes state as it moves through thewater cycle.Objective #2- Describe the water cycle B. Describe the process of evaporation, condensation, and precipitation as it relates to the water cycle.
