As part of a series of electronic professional development experiences, the NASA Explorer Schools project and the National Science Teachers Association are hosting a 90-minute Web seminar on Feb. 21, 2013 at 6:30 p.m. EST. Learn how to use authentic NASA mission data to investigate the composition and distribution of ices in the high-latitude regions of Mars through analysis of visible light, infrared light and gamma rays. The seminar includes information about a unique student extension activity, where students access a free computer simulation illustrating how gamma rays are used to determine the chemical composition of Mars.

This is the last time this Web seminar will be offered during the current school year.
