1. Knight’s Charge Get into groups of four, do NOT move chairs
This is the last chance for student selected groups, if today fails, I have a seating chart ready
In your group discuss:
“All of my kindness is taken for weakness.”
“We forget that the water cycle and the life cycle are one.” - Jacques Cousteau
Why you are here today

2. Water Cycle

3. H2Awesome Universal solvent- aka it dissolves a lot of stuff
Sticky- sticks to itself and others (cohesion and adhesion)
Water has a high heat capacity
It takes a lot of heat added to raise the temperature of water and a loss of a lot of heat to lower the temperature of water
**fun Friday water olympics?

4. Sun makes it run
The water cycle is just the movement of water and the changing of water from one state (solid, liquid, gas) to another
The heat from the sun drives the water cycle
The water cycle has no beginning and no end, not quite a “cycle”

5. -Ation Station Evapor-ation Condens-ation Precipit-ation
Transpir-ation
Accumul-ation
Infiltr-ation
And…… Runoff…. And so we begin

6. Evaporation
Heat from the sun causes water to change from liquid to gas (water vapor)
Contributes about 90% of water vapor to the air

7. Transpiration Like special plant evaporation
Plants have small pore on their leaves
These pores “sweat” water in a process called transpiration
Contributes 10% of water vapor to atmosphere
Quick quiz- what word means to sweat for people?

8. Condensation
When water vapor is high in the atmosphere, it is cooled down it changes from gas back to liquid, forming clouds or fog
*clouds can evaporate again- that’s why we can see clouds shrink
What would cause a cloud to grow?
Quick quiz- examples of water vapor in your life?
Fog, fogging glasses, water on iced tea, windows on cold day in the car

9. Precipitation
Condensed liquid water grows “heavy” and falls to the ground
There are tons of kinds of precipitation:
Rain, snow, sleet, ice, drizzle, mist, etc

10. Runoff
When water hits a saturated (all ready soaked with water) or impervious (water can’t move through it) surface, it flows over the ground
Of precipitation that falls on the ground, 1/3 runoffs the land into bodies of water

11. Accumulation/Surface Water
When the runoff ends up in rivers, streams, lakes, ocean, etc, all of which are examples of “surface water”

12. Infiltration
Infiltration is the process of water soaking and seeping into soil and becoming groundwater
Different soil=different amounts of infiltration

13. Groundwater
Once water infiltrates through the ground it becomes stored there as groundwater
Water that saturates (soaks) the rocks below ground is called an aquifer
Do you have well water? Then your water comes from an aquifer!
