A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
describe and record observable characteristics of weather, including hot or cold, clear or cloudy, calm or windy, and rainy or icy, and explain the impact of weather on daily choices.
measure, record, and graph weather information, including temperature and precipitation; and
compare and describe day-to-day weather in different locations at the same time, including air temperature, wind direction, and precipitation;
differentiate between weather and climate.
Patterns are regular sequences that can be found throughout nature.
Global winds, global pressure, and jet streams are the main patterns of atmospheric movement.
Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.
Variations in global winds, global pressure, and jet streams (causes) bring changes in local weather (effect). For example, jet streams (relatively narrow bands of strong wind) blow from west to east across the globe. As a weather system enters a jet stream, it is carried more swiftly across the globe (cause), impacting the weather in the locations along the jet stream (effect). Without jet streams, day-to-day weather would not change significantly.
Matter and energy are conserved, changing forms but maintaining quantities. Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes.
Atmospheric movement is driven by the flow of energy from the Sun through the hydrosphere and atmosphere, and, in turn, global winds, global pressure, and jet streams continue the flow of energy around the world.
