In this site we intend to provide the necessary tools to be able to specify the measurement of the circumference of the earth.
ΏSTICK? Ώ Measuring the Circumference of the Earth?
Stick is a collaborative project of international scope that invites students and their secondary teachers to repeat the experience of measuring the circumference of the earth as Eratosthenes did 2200 years ago, using simply a stick, a lot of imagination and a little information.
This project will be carried out with secondary school students and the main objective is to measure the perimeter of the Earth, in a similar way to that used by Eratosthenes more than two thousand two hundred years ago.
For this, each group of students and their teachers will
measure the height and shadow of a stick during the solar
midday of the autumn or September equinox. In the event that
the sky is cloudy, it can be measured on the first clear day
afterwards. Each school will share the values of their
measurements by completing the spreadsheet created in
