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.

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
