This lesson introduces the Earth system science spheres through model making and discussion.

Students will watch and examine a NASA animation of Earth’s rising surface temperatures over an almost 150 year period.

The activities in this guide will help students understand variations in environmental parameters by examining connections among different phenomena measured on local, regional and global scales.

The Earth System Satellite Images help students observe and analyze global Earth and environmental data, understand the relationship among different environmental variables, and explore how the data change seasonally and over longer timescales.
