LIVE INTERACTIVE YOUR DESKTOP December 19, 2011 Electromagnetic Spectrum: Remote Sensing Ices on Mars Presented by: Rudo Kashiri

AGENDA AGENDA Product overview: Buried Water Ice on Mars NASA Connection: Mars Odyssey Spacecraft Phoenix Mars Mission Featured lesson: Buried water ice on Mars Remote sensing ices on mars Remote sensing with gamma rays NASA Explorer Schools

BURIED WATER ICE ON MARS Middle and high school Physical and Earth science National Science Standards –Structure and properties of matter –Interaction of energy and matter Guided and open inquiry Use real data from Mars Lessons include: Teacher guide, Student guide, Multimedia presentations

Students learn how scientists use remote sensing data to draw conclusions about the physical and chemical nature of planets. LESSONS: Why Follow the Water Remote Sensing Ices on Mars Dirty Ice or Icy Dirt Mars Exploration Debate Dirty Ice Snowcones OBJECTIVE
