Caribou
(or Bald Eagle) Tracking Sheet
Jim
Minerich teaches 4th Grade at Pequot Lakes School in Pequot Lakes,
MN. He has a good strategy for tracking the satellite-collared caribou
with his class during the spring migration. They use a hand-held GPS
(Global Positioning System) to assist them in determining the distance
and direction each caribou moves between data updates.
"Our
classroom uses a hand-help GPS to help us determine the distance
and direction that each of the satellite-collared caribou move from
update to update. Our GPS has as one of its functions a distance
between waypoints function. Even though we know the data is days
apart the direction is given to us in degrees. Our GPS does not use
decimals so we have learned how to convert decimals to min/sec by
multiplying. (For how to do conversions from decimals to min/sec
see Conversions for Lat/Long.)
We use a worksheet to keep track of all the steps used for finding the distance
and direction. Print a copy of this:
