On the 22nd of March, 2021 from 11.45 AM to 13.45 PM Europe/Athens time (10.45 AM – 12.45 PM CET) students from Greece and South Africa joined forces to revive the Eratosthenes experiment, a 2250 year old inquiry based activity that bridges the wisdom of the past with the school of tomorrow. In this live event, students guided us step by step to Eratosthenes’s measurement using both simple materials and ICT tools and  collaborated to determine the circumference of the Earth using simple geometrical arguments. The event was flanked with observation of the Sun by means of solar telescopes from both hemispheres.

The event was organized by Ellinogermaniki Agogi and The University of the Free State in the framework of the international educational activity: “Eratosthenes Experiment”, under the auspices of the Greek Ministry of Education and Religious Affairs with reference number 167302/Δ2.

The event was broadcasted live in the YouTube channel of Ellinogermaniki Agogi.
