Goals for today
• The water cycle needs energy, where does it get it from?
• What order does it go in?• What are evaporation, condensation, and
precipitation?• What are runoff, infiltration, and
transpiration/evapotranspiration
Notes on pg 115
• The water cycle needs energy, where does it get it from?
• What order does it go in?• What are evaporation, condensation, and
precipitation?• What are runoff, infiltration, and transpiration
Sun warms water causing it to EVAPORATE. Water vapor CONDENSES to form clouds. Clouds become heavy and PRECIPITATE
•Now you will be creating a story, rhyming poem or song on pgs 116-117
•Include five of six main parts of the water cycle, underline each part
•20-50 seconds
• There once lived a little water molecule named Henry Harold Olson. His friends called him H2O for short. Today he is celebrating his 4.5 billionth birthday. Just when he was about to turn 4.5 billion years old…
• H2O was all shook up, but glad he finally stopped moving. These thoughts came too soon. Before he knew it, has being sucked back down into the ground. He was going through infiltration. He was getting sucked into roots and now was resting inside a beautiful flower. Finally a place he could call home.
• Before he knew it he was transpiring off the flower was rising again. He could see his short lived home getting smaller and smaller below him. He asked his friends what was going on. They said, “We’re going up into the sky! We just evaporated!”
“The next stop in his journey was way up in the sky. He found a friend named Debbie Dust and clung to her. Many of his friends did the same and made a cloud. Now all his friends had condensed and were together again, but then they heard a rumble and began precipitating. Will this ride ever end…

- Heat Transfer
How Heat Is Transferred• Heat is transferred in three ways: radiation,
conduction, and convection.
• When you lay at the beach, how do you experience all three
• Why is it colder on top of a mountain, even though you are closer to the sun?
• Using wavy lines or arrows show the three ways in which the sun heats the earth
Radiation
Conduction
Convection
2 ways to think of it
• Warm air rises so cold air takes it’s place
• Cold air is heavier and so it pushes down more so it moves. – Balloon pushing down

Land Breezes
• This causes wind to move from the land to the sea creating a
• land breeze• Happens • at night
• Top half – Answer in around 3 sentences. What causes wind
• Bottom half- • Draw a land or sea breeze and label with
arrows, and label hot air and cold air
• Create a Pie chart• Inside each piece instead of coloring, write
that letter over and over to fill the space
Fronts• = places where air
masses meet• 4 Types: Warm,
Cold, Occluded, Stationary
• Usually brings precipitation

Air Pressure
• Measure with tool called Barometer

Computer Weather Forecasting
– Stormy weather, clouds, and precipitation accompany low air pressure.
• Predicting:
– What weather would you forecast for Monday and Tuesday? Explain.
