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.

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.

In this NASA-JPL lesson, students create a model of a volcano, produce and record lava flows, and interpret geologic history through volcano formation and excavation. 

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. 

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.

Compare pictures of different volcanoes. Then visit NASA's Space Place to learn about volcanoes and answer questions about volcanic eruptions.

Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Watch NASA videos about aerosols and volcanic ash.

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