    Congratulations to the Purple Lab winners of the Erotosthenes Award for most accurately calculating the circumference of Earth. Students used GPS coordinates and paced the distance between 2 points and, with some simple geometry, estimated the polar circumference of our planet. The Purple Lab had a percentage of error of 1.4 The class earned a "Half Moon" party for their efforts.
