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,...

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...

Snow Cover By Latitude
Young scholars 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.
