Measure The Earth

The "measure the earth like the ancients" Noon Day Project is done twice a year. (Fall registrations close around 9/14. They do it again in March.) You may enjoy reading the "Measuring With the Mind chapter of Joy Hakim's The Story of Science first.

Fall Time Frame: September 7th – October 11th
Target Measurement week(s): September 17-28

Purpose: To recreate the remarkable measurement of the circumference of the earth that was done over 2000 years ago. Using only simple tools such as rulers, protractors, and meter sticks, students will measure shadows cast by a meter stick at different locations on the earth.
