MS-ESS2-5 Earth’s Systems
|
Students who demonstrate understanding can: Collect 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 (such as with condensation).
|
Assessment Boundary: Assessment does not include recalling the names of cloud types or weather symbols used on weather maps or the reported diagrams from weather stations.

Disciplinary Core Ideas
|
Cause and Effect:
- Cause and effect relationships may be used to predict phenomena in natural or designed systems.
|
Planning and Carrying Out Investigations:
- Planning and carrying out investigations in 6-8 builds on K-5 experiences and progresses to include investigations that use multiple variables and provide evidence to support explanations or solutions.
- Collect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions.
|
Weather and Climate:
- Because these patterns are so complex, weather can only be predicted probabilistically.
