It's time for the Noon day Project! GMT

The Goal of the Noon Day Project  is to have students measure the circumference of the earth using a method that was first used by Eratosthenes over 2000 years ago.  Students at various sites around the world will measure shadows cast by a meter stick and compare their results. From this data students will be able to calculate the circumference of the earth.
