The students of our class participated on Monday, March 20, 2023, the day of the Spring Equinox, in the International Student Action "The Experiment of Eratosthenes to measure the length of the circumference and the radius of the Earth". In the context of this action and with simple materials, we took measurements and performed the relevant calculations resulting in calculating the radius and circumference of the Earth with extreme precision.At the vernal equinox, which marks the beginning of spring, the Sun is directly above the equator. On the same day, thousands of male and female students throughout Greece, with the guidance of their teachers, repeated the Eratosthenes Experiment in their school yards. This experiment is among the 10 most beautiful scientific experiments in the history of Physics.With this action it was possible to calculate the circumference and radius of the Earth, in a way similar to that used by Eratosthenes over 2000 years ago. In the 3rd century e.g. the great mathematician used as his only tools a rod, "steppers" of the time for measuring distances, basic principles of trigonometry and clear thinking
