Students observe how air quality changes over time, for a selected location, using data from the United States Environmental Protection Agency (EPA).

GLOBE protocols and learning activities that complement the Volcanic Eruptions phenomenon through hands-on investigations are detailed. 

The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. 

The Great Smoky Mountains have a unique climate and weather pattern. Students will review a Landsat image and read about the history of the area and why Native Americans called the area “Shaconage.” Then they will answer the questions about what caused the unusual “blue smoke.”

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

The world's surface air temperature is getting warmer. Whether the cause is human activity or natural changes in the Earth System—and the enormous body of evidence says it’s humans—thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution. 

In addition to the changes brought about by natural forces, it has recently become apparent that a relative newcomer to planet Earth — the human being — has become a powerful agent of environmental change.

Students analyze four data visualizations focused on the topic of sea level.  They use a jigsaw method to explore and communicate their findings to their peers.

GLOBE protocols and learning activities that complement the Soil Moisture phenomenon through hands-on investigations are detailed. 

A key practice of successful scientists and engineers is the ability to clearly communicate the ideas and methods they develop. Being able to review and critique the ideas of others are fundamental activities of professional STEM professionals.
