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

Examine the images to see the projected differences in land use between 1900 and 2100. 

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!

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.
