This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.

Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.

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.

Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.

Students observe seasonal images of Monthly Leaf Area, looking for any changes that are occurring throughout the year.

Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

This mini-lesson features time-series graphs of mean salinity at the surface for the Arctic and Antarctic regions. A series of questions guides students in their analysis.

For over 20 years, satellite instruments have measured the sea surface height of our ever-changing oceans.  This video of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.

The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using two maps created using NASA satellite data for 2017, students review the seasonal differences of snow and ice extent and answer questions on their observations.

Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes.
