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. 

Students move through a series of short activities to explore and evaluate global solar radiation data from NASA satellites.  In this process, students make qualitative and quantitative observations about seasonal variations in net energy input to the Earth System.

Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.

Students collect and analyze temperature data to explore what governs how much energy is reflected. 

To investigate the different rates of heating and cooling of certain materials on earth in order to understand the heating dynamics that take place in the Earth’s atmosphere.

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.

Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.

In this activity, students explore the Urban Heat Island Effect phenomenon by collecting temperatures of different materials with respect to their locations.  

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