BURIED WATER ICE ON MARSBURIED 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.

LESSON IN DETAILLESSON 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

OBJECTIVESOBJECTIVES

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 PROPERTIESICE PROPERTIES• Phase change

• Molecular structure

• Frost point temperature

• Sublimation
