Warm Up 3/6Explain the science behind hang gliding.
Pass you article summaries to the aisle.
Objective:◦SWBAT
Use air pressure to explain 3 lab demos.
Agenda:◦Gradesheet◦Weather◦Air Pressure Demos◦Notes: Air Pressure◦Closing
Homework: ◦Textbook Reading Packet due Monday
GradesheetMs. McGowan is handing back
the following assignments. Please enter them into your Q3 gradesheet◦Atmosphere Unit Test (50 points)
Weather
Who would like to present yesterday’s weather?
Air Pressure Demos:Crushing Cola
What will happen to a hot soda can placed in a cold bath of water?
Air Pressure Demos: Erlenmeyer Egg
Can an egg fit into an Erlenmeyer flask?
Air Pressure Demos:Wet Head
What will happen if we place an index card on a cup of water and flip it over?
Warm Up 3/7Use the idea of air pressure to
explain why the cola can imploded when placed in a cold bath of water
Pass your air pressure demos WS to the aisle
Objective:◦SWBAT
Explain how the different heat capacities of sand, soil, and water create sea breezes and other winds.

Notes: Air Pressure
Air Pressure—the force per unit area of air’s weight (due to gravity) on Earth’s surface
Air moves from areas of high pressure (hot areas like Earth’s surface) to areas of low pressure (colder areas like the atmosphere), creating wind◦Air pressure decreases with
increased altitude
Sand, Soil, Water LabIn partners, measure the
difference in temperature change between beakers of sand, soil, and water
ClosingWhy do we have sea breezes?
Warm Up 3/10•Think back to our lab on Friday…
•Which substance heated up the fastest? •Which substance cooled down the fastest?
Objective:◦SWBAT
Explain how differences in temperature and air pressure create 1 of the 4 local wind patterns
Agenda:◦Weather◦Review Homework Packet◦Review Sand, Soil, Water Lab◦Notes Foldable: Local Winds◦Closing
Homework: ◦None!
Weather
Who would like to present yesterday’s weather?
Air Pressure PacketTake out your air pressure
homework packetIt will be checked for completionThen, move around the room,
checking your answers with those posted on the wall
Sand, Soil, Water LabThinking back to the lab….
◦Why did the sand heat up the quickest?
◦Why did the water take the longest to cool?
WindWhat do you think causes wind?
◦Differences in temperature!Two types of wind patterns
◦Local◦Global
Local Winds100km or less in distanceFour types of local winds
◦Sea-Breeze◦Land-Breeze◦Mountain Breeze◦Valley Breeze
Sea Breeze Land-Breeze
Sea Breeze
Land Breeze
Mountain and Valley BreezesUse what you know to draw air
movement arrows for mountain and valley breezes on your foldable◦DO THIS IN PENCIL!
ClosingChoose a local wind that we
learned about today.Explain how temperature and air
pressure create this local wind.
Warm Up 3/11Choose a local wind that we
learned about yesterday.Explain how temperature and air
pressure create this local wind.
Objective:◦SWBAT
Explain how differences in temperature and air pressure create 1 of the global wind patterns
Agenda:◦Weather◦Notes: Global Winds◦Global Winds Diagram◦Closing
Homework: ◦Finish your Global Winds Questions

Sea Breeze
Land Breeze
What factors affect wind?Coriolis effectFriction
Notes: Coriolis EffectCoriolis effect—tendency of an
object moving over Earth’s surface (airplane, rocket, wind) to curve away from its path of travel◦Caused by Earth rotating◦Therefore, objects curve to the right
in the Northern hemisphere and to the left in the Southern hemisphere
Notes: FrictionFriction—force resisting surface
winds◦Rough land=more friction=move
slower=more deflection from Coriolis effect (and vice versa)
◦Higher altitude=less friction=move faster=less deflection from Coriolis effect (and vice versa)
Notes: Global WindsGlobal winds—uneven heating of
Earth’s surface creates pressure differentials and therefore predictable winds on a worldwide scale
Global Winds DiagramUse pages 422-425 in your
textbook to label your global winds diagram
When you finish, we will review your diagrams as a class
If you finish early, please begin working on your global winds questions on the back of your diagram worksheet
ClosingExplain how differences in
temperature and air pressure create 1 of the 3 global wind patterns you learned about today.
Warm Up 3/12How does the Coriolis effect and
friction impact wind traveling over a smooth portion of Maryland’s surface?
Objective:◦SWBAT

Review: Global Winds DiagramFollow along as we review our
global winds diagram as a classWhen we finish, you will turn in
your worksheet for a grade
Notes: Global Winds and WeatherLow Pressure
◦When hot air rising◦Rhymes with snow or Lowsy/Lousy
weather◦At latitudes: 60N, 0, 60S
High pressure◦When cold air is sinking◦Rhymes with dry weather◦At latitudes: 90N, 30N, 30S, 90S
Global Winds StationsMs. Goldsmith and Ms. McGowan
will place you in groups of 3You will have 5 minutes at each
station to analyze the artifact in front of you and answer the appropriate questions
ClosingExplain how differences in
temperature and air pressure create 1 of the 3 global wind patterns you learned about today.
Compass PartnerMs. Goldsmith and Ms. McGowan
will play 8 song clipsAt the stop of each clip, you are
expected to find one partner and put their name in one of your compass partner boxes◦If you are writing your partner’s
name in the north box, they must write your name in their north box!
