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

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

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

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.

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.

friction impact wind traveling over a smooth portion of Maryland’s surface?

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!
