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.

Students review a video showing how the ocean is warmed by solar energy. This is the first video of a four-part series on the water cycle, which follows the journey of water from the ocean to the atmosphere, to the land, and back again to the ocean.

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!

This investigation is part of the NASA: Mission Geography Module "What are the causes and consequences of climate change?" that guides students through explorations in climatic variability and evidence for global climate change.
