2 water cycle
Transcript of 2 water cycle
Standard 4~4.1: Summarize the processes of the water cycle (including evaporation, condensation, precipitation, and runoff)
Today, we are going to summarize the processes of the water cycle.
Evaporation,Raise arms into the air.
Condensation,Brings hands together above head, forming large cloud shape with arms.
Precipitation,Lower arms moving fingers for rain, sleet, snow or hail
Runoff too.Move hands in a downward motion as if running off of a hill
Parts of the water cycle;Students join hands
They continue, yes the do.Students move in a clockwise large circle to model cycle.
Water Cycle Song(to the tune of “Oh My Darling Clementine”)
Students stand around the room to form a big circle.
EvaporationIn the water cycle, water
changes state between liquid, gas, and solid. The Sun is the
energy source for this cycle. The Sun causes water to evaporate from lakes, oceans, and other
bodies of water. We cannot see the water rising because it is in
its gaseous state.
TranspirationDo plants sweat?
Well, sort of.... people perspire (sweat) and plants transpire. Transpiration is the process by which plants lose water out of
their leaves. Transpiration gives evaporation a bit of a hand in
getting the water vapor back up into the air.
(a type of evaporation)
water vapor
water vapor
CondensationAs the water vapor rises, it cools and condenses. Condensation occurs when the water vapor
turns from a gaseous state back to a liquid. This is when clouds
form.
Precipitation Precipitation can fall as rain,
snow, sleet, or hail.
snow~ falls when the water reaches a temperature below 0 degrees C (32 degrees F).
sleet ~ rain falls from clouds as a liquid but freezes along the way. The rain falls as small chunks of ice called sleet.
hail ~ is made of ice, too. The ice chunks are much larger than sleet. Hail forms inside the tall clouds of a thunderstorm. Most hailstones are the size of peas. However, some are bigger than baseballs.
Runoff After precipitation, water flows
over the Earth's surface as runoff. Runoff gathers in lakes,
oceans, rivers, and streams. Over time, water collects in
glaciers an ice caps.

Now let's act out the water cycle!
Reader's Theater scripts are under attachments.
Your Task In groups of 9, find a safe place in the classroom to practice your parts.
Make any props necessary to make your group original.
You will perform for the class.
1
A It heats the water and causes some to evaporate.
B It forces precipitation out of the clouds.
C It causes a warm front to move in.
D It creates water condensation that creates ice crystals.
2
A evaporation
B condensation
C precipitation
D runoff
3 Which of these does not happen to runoff after it falls from the sky as precipitation?
A It gathers in a lake.
B It soaks in the soil.
C It evaporates.
D It forms a low-lying cloud.
4 As water vapor rises in the atmosphere, it cools and becomes liquid water. This process is known as:
A evaporation
B condensation
C transpiration
D precipitation
5 When temperatures drop below 0 degrees C (32 degrees F), the water droplets that make up clouds can freeze. What can happen when this occurs?
A The droplets break the clouds apart.
B It begins to sleet.
C The droplets fall to the ground as snow.
D The snow melts into rain.
