Teaching Tips | Science | Pedagogy |
- Younger students (middle grades, lower high school) may need clarification and vocabulary support from educator.
About the Science
- A time-series view of September Arctic sea ice concentration from 1979 to 2014.
- Visualization animates changes in Arctic sea ice at its minimal extent (September) from 1979-2014. Part of the National Snow and Ice Data Center (NSIDC) State of the Cryosphere web resources.
- Passed initial science review - expert science review pending.
About the Pedagogy
- Attractive graphic is easy to interpret even though no quantitative data is given.
- Dramatic image centered on the North Pole using satellite data overlaid onto NASA's Blue Marble. Additional Arctic animation (March/maximum extent) and Antarctic extents (September/maximum and March/minimum), as well as other excellent resources on the cryosphere, are in the sidebar.
