Crosscutting Concepts
Crosscutting Concepts Addressed
1) Patterns, Grades 9-12:
Patterns in rates of change and other numerical relationships can provide information about natural systems.

  • NASA: What to See in CME Images
  • NASA: The Difference Between Solar Flares and CME



2) Scale, Proportion, and Quantity, Grades 9-12: The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs.
Activities correlating to this Crosscutting Concept:
  • NASA ScienceCasts: Carrington Class CME Narrowly Misses Earth
  • NASA Goddard: Many Views of a Massive CME
  • NASA Goddard: Comparing CMEs
  • NASA: Earth-Directed CME Lights the Sky



3) Stability and Change, Grades 9-12: Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.
