QUESTIONS FOR STUDENTS
QUESTIONS YOUR STUDENTS ARE LIKELY TO IDENTIFY AS THEY GO THROUGH THE PROBLEM
- How do clouds form? How do Polar Mesospheric Clouds (PMCs) form?
- What/where is the Mesosphere?
- What are the distinct layers of the atmosphere?
- What are the thermal
characteristics (temperature changes), chemical composition,
movement, and density of atmosphere layers?
- What are "noctilucent" clouds
- What are "polar mesospheric clouds", or PMCs?
- How do Polar
Mesospheric Clouds (PMCs) form?
- What are the condensation particles found
in PMCs/ NLCs?
- What is "cosmic dust"?
- What are "gravity waves?"?
- Do gravity waves have a role in
the formation of Polar Mesospheric Clouds?
- Does man-made pollution
affect the formation of ice in the mesosphere?
- What will the AIM satellite
- What is climate change?
STUDENT AERSOLS AND POLLUTION PBL ACTIVITY OBJECTIVES
(some or all may
be appropriate depending on your state's standards
and the needs of your curriculum.)
- As a result of taking part in this activity,
students should be able to:
- Discuss why Polar Mesospheric Clouds
(PMCs) form and why they vary.
- Demonstrate understanding of PMCs and
the thermal, chemical and dynamical environment in which
to quantify the connection between these clouds and the meteorology
of the polar mesosphere.
- Recognize the variability in the mesospheric
climate and its relationship to global change.
- Identify PMC abundances,
spatial distribution, particle size distributions, gravity
wave activity, cosmic dust influx
to the atmosphere and precise,
vertical profile measurements of temperature,
H2O, OH, CH4, O3, CO2, NO,
- Take into account past PMC changes
and present trends as indicators of global change.
