This investigation introduces students to the significant environmental changes occurring around the world. The investigation uses NASA satellite images of Brazil to illustrate deforestation as one type of environmental change.

This USGS activity leads students to an understanding of what remote sensing means and how researchers use it to study changes to the Earth’s surface, such as deforestation. 

In this 5Es lesson, students will uncover how changes in global air quality have impacted human health in cities between 2000 and 2019.

The purpose of this activity is to have students use an Earth Systems perspective to identify the various causes associated with changes to Earth's forests as they review Landsat imagery of site locations from around the world.

Watch NASA videos about aerosols and volcanic ash.

Examine the images to see the projected differences in land use between 1900 and 2100. 

Compare images from two volcanic eruptions in the Kuril Islands which occurred ten years apart and complete a graphic organizer for impacts on different Earth spheres. 

Use the AirNow.gov website to determine current air quality in US locations, as well as other information.

Students will synthesize information from maps that show population, concentrations of PM_2.5, and PM_2.5-attributable mortality across the globe in order to draw conclusions about the relationship between particulate pollution and human health. 

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