LSD Units

Explain patterns of changing weather and how they are measured.
Key concepts: Weather patterns - cold front, warm front, stationary front, air mass, humidity.
Tools: Thermometer, rain gauge, wind direction indicator, anemometer, weather maps, satellite weather images.
Real-world contexts: Sudden temperature and cloud formation changes; records, charts, and graphs of weather changes over periods of days; lake effect snow.


LSD Units

Explain the behavior of water in the atmosphere.
Key concepts: Water cycle - evaporation, water vapor, warm air rises, cooling, condensation, clouds. Precipitation - rain, snow, hail, sleet, freezing rain. Relative humidity, dew point, fog. See PCM-IV.2 m.1 (changes of state), EH-V.2 m.2 (water on the earth's surface).
Real-world contexts: Aspects of the water cycle in weather, including clouds, fog, precipitation, evaporating puddles, flooding, droughts.


LSD Units

Describe health effects of polluted air.
Key concepts: Effects - breathing difficulties, irritated eyes. Sources - car exhaust, industrial emissions. Acid rain.
Real-world contexts: Locations and times where air quality is poor; local sources of potential air pollution; ozone warnings.
