Electromagnetic Spectrum:Remote Sensing Ices on Mars
Presented by: Rudo Kashiri
AGENDA
• Product overview:Buried Water Ice on Mars
• NASA Connection: Mars Odyssey Spacecraft Phoenix Mars Mission
• Featured lesson: Buried water ice on MarsRemote sensing ices on marsRemote 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 remotesensing data to draw conclusions about thephysical 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

LESSON IN DETAIL
MATERIALS• Student Guide (1 per student) • Computer with projector, or overhead with
transparency • Computers (extension) Optional:• 1 clear pitcher with liquid water and water ice • 1 thermometer
OBJECTIVES
Compare maps of Mars showing different types of data to characterize the types of ice at the polar regions of Mars during different seasons. Data:– Visible albedo– Surface temperature – Elemental composition
ICE PROPERTIES• Phase change• Molecular structure• Frost point temperature• Sublimation

Remote Sensing Ices on Mars
Objectives: Students explore an online simulator to learn more about how gamma rays that are produced at the surface of Mars are used to determine the composition of the surface.
