In this mini lesson, students use in-water profiles of historical ocean data to analyze how sea surface salinity varies with depth.

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 examine satellite images of a recently formed island to identify areas of erosion and deposition.
Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations.
Phytoplankton distribution background information.
An urban heat island is a phenomenon that is best described when a city experiences much warmer temperatures than in nearby rural areas. The sun’s heat and light reach the city and the country in the same way. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.
Students observe the surface temperatures of a variety of surface types found in a suburban environment.
Background information on soil moisture.
Watch NASA videos about aerosols and volcanic ash.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
