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 Standard: Today I am learning about weather instruments because they are
used to forecast the weather.
Opening: What would I wear in . . .
Work Session:• Return all graded work• Notes on Instruments• Create Isobar and Isotherm Maps
Closing: Luck of the Draw

Wind Sock
Anemometer

• Counted the number of times the cup spun in a specific amount of time.
Your eyeballs
Measures air temperature
Thermometer
Barometer• Measures air
pressure. • It tells you whether or not the pressure is
rising or falling. A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions.
Rain GaugeMeasures the amount of rain that has fallen over a specific time period
• Measures the relative humidity• Two thermometers are used in a sling
psychrometer. • Wet the cloth of one of the thermometers and swing the psychrometer around a few times. • Water evaporates from the cloth, causing the temperatures on that thermometer to be lower than the other.
