In Earth System Science, underling factors affecting observable phenomena can be difficult to identify and describe. The Iceberg Diagram diagram uses the metaphor of an iceberg to demonstrate the idea of visible vs hidden as it relates to Earth science phenomena. This teaching strategy helps students to see beyond the obvious and to develop their awareness of the underlying causes, relationships, and/or conditions that can contribute to phenomenological events. It also provides a framework for digging deeper into phenomena-driven lessons in Earth Science.
This graphic organizer may be used to help students analyze the processes and components of Earth System phenomena.
Students review the NASA video showing biosphere data over the North Atlantic Ocean as a time series animation displaying a decade of phytoplankton blooms and answer questions that follow.
Review this mapped plot of the historic Ocean Chlorophyll Concentrations of key locations around the world for the period of 1998-2018. Also, consider using the Map Cube to help students with deeper dives into data analysis. Credit: NASA, NOAA
