MYP Unit Question: What should I wear today?

Area of Interaction: Environment

Learner Profile: Communicator

Standard: Understand how the distribution of land and oceans affect climate and weather.

Learning Target: Today I’m learning how the temperature of the atmosphere affects weather because it impacts my environment.

Opening: Beach Video – which way is the wind blowing?

Work Session: Review conclusions of heat lab Video: Global Winds Notes over land and sea breezes

Closing: What’s the weather like in

Let’s review the lab from yesterday.1.What type of heating was occurring over the “land” and “ocean?” (radiation, convection, or conduction)

2.Which one heated up the fastest?

3.Which one cooled the fastest?

Land

Water

In your notebook, page ____ draw this image.Title the page “Land and Sea Breezes.”

Under the Land and Sea Breeze image write the following information:

Weather is caused by unequal heating of earth’s surface. Air moves from areas of high to low

areas of concentration (high to low pressure)

Analyze this:During the day, the land warms up quicker than the water. What happens to the warm air above the land? What replaces the warm air? Where does the cool air come from?

This is called a SEA BREEZE

So what do I write down?

Sea BreezeOccurs in the day timeWarm air from land rises up (low pressure)

Cool air from the water replaces it

Why is it cooler on the beach at night than it is during the day? Where is the warmer air located? Where is the breeze coming from?

This is called a LAND BREEZE

Land BreezeOccurs at nightWarm air from ocean rises (low pressure)Cool air from the land replaces it

Inches to Mill bars (mb)• 1029 mb = 30.39 inches• 1002 mb = 29.6 inches• 1000 mb = 29.53 inches• 960 mb = 28.34 inches

To convert inches of mercury to millibars, multiply the inches value by 33.8637526
