8th Grade (SCI) Earth Space Science Standards [ESS2] Earth’s Systems
SCI-MS.ESS2.05 Use data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.
Clarification Statement: Emphasis is on how air masses flow from regions of high pressure to low pressure, causing weather
(defined by temperature, pressure, humidity, precipitation, and wind) at a fixed location to change over
time, and how sudden changes in weather can result when different air masses collide. Emphasis is on how
weather can be predicted within probabilistic ranges. Examples of data can be provided to students (such
as weather maps, diagrams, and visualizations) or obtained through laboratory experiments (e.g.;
condensation). Disciplinary Core Ideas ESS2.C: The Roles of Water in Earth's Surface
The complex patterns of the changes and the
movement of water in the atmosphere,
determined by winds, landforms, and ocean
temperatures and currents, are major
determinants of local weather patterns.
ESS2.D: Weather and Climate
Because these patterns are so complex,
weather can only be predicted
Student Learning Targets:
I can identify the characteristics that define air masses.
I can describe the interactions between a warm air mass and a cold air mass along a warm/cold font (include precipitation).
I can describe the four factors necessary for cloud formation.
I can predict the weather conditions before and after a warm front and a cold front.
Skills (Performance) Targets
The Student can ...
