Electromagnetic Spectrum: Remote Sensing Ices on Mars

In this web seminar, educators learned how to use authentic mission data to investigate the composition and distribution of ices at the high latitude regions of Mars. They analyzed data collected by Mars spacecraft using three different portions of the electromagnetic spectrum–visible light, infrared light, and gamma rays. The seminar also included information about incorporating a unique student extension activity into the classroom, where students access a free computer simulation illustrating how gamma rays are used to determine the chemical composition of the Mars depending upon the type of gamma ray photons and neutrons released from the planet.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NASA Explorer Schools invests in science, technology, engineering, and mathematics educators to inspire and engage a whole generation of future scientists, engineers and technicians that NASA needs to continue our journey. NES gives educators of grades 4-12 free access to NASA’s people, missions, research, and facilities. We take the work out of searching through thousands of materials on the NASA website and provide a comprehensive set of teaching materials for dozens of STEM concepts.
