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

EXTENSION ACTIVITY
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.
