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

What is the surface temperature
of the ice cap during the winter?
Do you agree or disagree with either or
both of the students below? [Use chat]
• Student 1: I think the ice caps are made of
water ice. There is more water ice in the winter
when it is colder and less in the summer, just
like on Earth.
• Student 2: I don’t think we can figure out what
kind of ice the caps are made of because other
ices, like carbon dioxide and methane, are also
bright just like water ice.

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.
