Quantifying Land Changes Over Time Using Landsat
"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Remote Sensing - What Can We See When We Can't Touch?
Students discover how remote sensing is used to identify the signatures of life even when the particular life form is not directly observable. They investigate how a satellite "sees" objects on the surface of Earth.

Geography: Snow Cover on the Continents
Students create maps of snow cover for each continent by conducting Internet research. After estimating the percentage of continental snow cover, they present their findings in letters, brochures or Powerpoint presentations.

Volcanoes in Space
Young scholars research volcanoes on the Internet to compare/contrast the volcanoes on Earth to the ones found on Io, a moon of Jupiter. Students list the similarities and differences in science journals, and illustrate pictures of the...

Comparison of Snow Cover on Different Continents
Students use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date and analyze the data for each map, corresponding text file to determine an estimate of snow cover for...

Snow Cover by Latitude
Students create graphs showing the amount of snow coverage at various points of latitude and compare graphs.
Curated OER
Snow Cover By Latitude
Learners create graphs comparing the amount of snow cover along selected latitudes using data sets from a NASA website. They create a spreadsheet and a bar graph on the computer, and analyze the data.
