4. WaterCycle

5. Watch how water moves through the atmosphere and ground.

6. H2O H2O H2O H2O H2O H2O

7. H2O H2O H2O H2O H2O H2O Yep, let’s condense! Its cold up here!

8. H2O H2O H2O H2O H2O H2O Yep, let’s precipitate! We’re a lot heavier when we’re all stuck together!

9. H2O H2O I’m gonna run off now. Me too! Wow, I could go all the way to the ocean like this!

10. H2O H2O H2O H2O H2O H2O H2O H2O H2O H2O H2O Yes, we can join our bretheren in the aquifer. Lets percolate into the porous earth!

11. H2O H2O H2O H2O H2O H2O Well DUH! It’s a like a cycle…so it like happens over and over! Didn’t we already do this part?

33. ...or is it neither because cycles don't have a begining or end? ...or is it the beginning? The End...

34. Words to Watch: condensation – p485 runoff – p485 watershed aquifer photosynthesis percolation - p485 respiration – animals using food as they breathe decay – organisms breaking down after they die

35. Wise Choices:Choose one. Write it and then draw a picture of a solution to one problem. • Conserving Water – There is a limited supply of fresh water. Some areas have a water shortage. • Reducing CO2– Burning gasoline in cars & burning coal for electricity puts carbon dioxide (CO2) into the air and can cause global warming. • Helping Ozone Layer – Some chemicals (chlorine) can break down ozone (O3) which helps block radiation from the sun. • Reducing Nitrogen Runoff – Fertilizer and cattle waste can runoff from farms and put too much nitrogen into rivers and streams. This harms aquatic life, and increases weed and algae growth.
