Performance expectationEvaluate data and communicate information to explain how the movement and interactions of air masses result in changes in weather conditions.
Examples of evidence sources could include station models, surface weather maps, satellite images, radar, and accepted forecast models. Emphasis should focus on communicating how the uneven heating of Earth’s surface and prevailing global winds drive the movement of air masses and their corresponding circulation patterns, the interaction of different air masses at frontal boundaries, and resulting weather phenomena.
Analysis is limited to surface weather maps and general weather patterns associated with high and low pressure systems.
Every item written to HS-ESS2-8 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
Obtaining, Evaluating, and Communicating Information
Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
