Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

In this mini-lesson activity, students use art to demonstrate their knowledge of an aurora. 

In this activity learners examine the difference between aurora and airglow, while learning about NASA’s ICON Mission.

Use art to demonstrate your knowledge of aurora!

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.

Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless.
