Proposal from 4th Grade Science Classes at
Ida Elementary School
Teacher: Mrs. Maynard
We are learning about Megadunes. We have done some research and
learned they can be up to 100 kilometers long and the Katabotic
winds help form the Megadunes form. They appear to look like sand
dunes and the satalite images are some of the most detailed of
these ice formations.
The Megadunes are located on the East Antarctic ice
plateau (81 lat., 130 long.) and cover about 500,000 square kilometers.
Interesting features about Megadunes:
We have been studying several ice formations on Antarctica but found
Megadunes most interesting because so little research has currently
been done and we have never heard of them or learned about them. They
are neat because they look like sand dunes but are made out of ice.
The formations are also so huge you can not see where one begins and
another ends. How they form is also interesting. We have learned about
force and motion and the speed of the winds blowing over the ice would
be a constant pushing force moving the ice in the same direction as
Our theory on what geologic processes are occurring to create Megadunes:
We talked about what effect there may be on the ground below the ice
from the constant Katabotic winds at the surface. We would like to
see if over time the ice wears down and then causing the rock underneath
to also wear down. Maybe this will one day become clay.
Support for additioinal funding:
This will require a lot of further
exploration as to how surface winds may affect the bedrock. We need
additional funding to conduct scientific experiments in the lab to
better understand these processes and discover how the formation of
the earth is being changed.
