Students in Charlie Yates’ pre-calculus classes participated in a national effort to measure the circumference of the world from the Coal Ridge High School parking lot. The experiment replicated the efforts of Eratosthenes, a Greek living in Egypt under the Ptolemy Pharoahs in about 200 BC.
Eratosthenes measured the angle of a shadow of a stake in a dry well in Alexandria, Egypt, on the same day that a similar stake in Syene, Egypt, about 500 miles to the south showed no shadow. From this very rudimentary experiment, he calculated the circumference of the world within 15 percent ” quite a feat for the day.
The students did a modern-day version. The experiment was supposed to take place on the autumnal equinox; however, the students were not in school that day. On Monday, Sept. 25, they performed the experiment.
Because of their knowledge of latitude, they needed only one stake.

The 2005-06 school year provided the first opportunity for private schools in Colorado to participate in CSAP testing. Alpine Christian Academy achieved scores on par with Aspen schools, and higher than other schools in the Roaring Fork Valley.
ACA serves the educational needs of children from preschool through high school. Enrollment this fall jumped from 107 to 130, due to increased academic offerings, restructuring of the preschool, and participation with home-schooled students.
