Warm-Up February 20Why does warm airRise and cold air sink?Difference in temperature and density.Earth Science Rocks!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 am learning how to read a weather map because it will tell me what to wear each day.
Opening: What should I wear today in ______________? Work Session: Weather Symbols on a Weather Map
Predict the Weather
Closing: Exit Ticket Map SymbolsWhat should I wear today in Unalakleet, Alaska?Temp: 9 Fair & BreezyWind Chill: -12 (feels like)
Humidity: 51%
Wind Speed: 25 mph E
Visibility: 10 miDew point: -6

Longest sled race in the world!
Meteorologists use weather maps and symbols to describe the weather.Just like how you use :) in a text message to indicate a smile.
8Where do Meteorologists get their information?870 land-based air stations 150+ countries An instrument (called a radiosonde) attached to the balloon measuresthe atmospheric pressure, air temperature and relative humidity. Wind speed and direction are calculated by tracking the instrument with a high-gain antenna (similar to a satellite-TV dish).Balloon rises an average of 1000 feet per minute. Bursts around 100,000 ft above ground
Two types of Satellites
Geostationary satellites - constantly monitor the Western Hemisphere - 22,240 miles above the EarthPolar-orbiting satellites - circles the Earth around the poles - 540 mi. above the Earth
Placed in space by a rocket.

Tell me how you have been a thinker while analyzing todays data.CycloneAn area of low pressure is called a cyclone. Its winds spiral toward its center.The winds spin counterclockwise.
AnticycloneAreas that have high air pressure are called anticyclonesCooler, denser air sinks and moves out of the center towards areas of lower air pressure.The winds rotate clockwise
