If you are partaking in our teacher training program your homework is
to read about an area of personal interest that you find on this CD-ROM
about Geomagnetism. As you research the disk please click on the
links that are associated with the readings. These links will include
glossary definitions, and figures that support defined terms within the
readings (the “back” button will always return you to your topic).
While reading your topic of interest please make notes about points that
are fascinating and perplexing. Our first discussions will center
on your topics of study, questions that arose, and some of the information
contained within this CD-ROM. Again, the intent is for you to find
a topic for discussion and a starting point related to your own interests.
Here are two images that can be used help students develop a 3-dimansional
image of the Earth's magnetosphere. IMAGE
1 is black and white. IMAGE
2 is in color. I found that having the students identify, label
and color in the black and white image helped tham to learn the different
sections.
Here are some topics or questions which you could research;
Inclination / Declination Angle
Top of the world, North Pole?
The Magnetosphere Shape
Magnetopause, Magnetotail, Bow Shock
Main divisions
Day / night sides
Van Allen Belts
Plasmasphere / Plasma Sheet
Cusps and Auroral Ovals
Charge Drift and Ring CurrentsWhat causes the Earth's magnetic fields?
How is it created?
Proof that it existsHow far does our magnetopause extend into the atmosphere?
What evidence is there for magnetic reversals?
Where is our current magnetic north pole?
