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

In this lesson, Observing Earth’s Seasonal Changes, students observe patterns of average snow and ice amounts as they change from one month to another, as well as connect the concepts of the tilt and orbit of the Earth (causing the changing of seasons) with monthly snow/ice data from January 2008

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.

The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.

GLOBE protocols and learning activities that complement exploration of the Flow of Energy and Matter are outlined.

This activity is one of a series in the collection, The Potential Consequences of Climate Variability and Change activities. 

 Air, Water, Land, & Life: A Global Perspective

Students will analyze surface temperature and solar radiation data to construct explanations about the relationship of seasons and temperature to the amount of solar energy received on Earth’s surface.
