Eratosthenes Experiment, 19-20 March 2015
A new, enriched edition of theEratosthenes Experimentis coming very soon! This year the experience will be double: it will last two days and will take place on19-20 March 2015.
The experiment will take place on the19thof March in Europe and North Africa (due to the fact that on the20thof March we will have in that area a solar eclipse) and on the20thof March for the rest of the world, on the equinox day. Thus, for your matchup ' if no other schools can be found on the same longitude - you can consider the existence of a virtual school on the equator with experimental data 0 (shade of a one-meter stick measured at a certain time). This way you can also have an accurate outcome by conducting the experiment by yourself.
In 2014 a total of 350 schools in 37 countries participated in the Eratosthenes Experiment to measure the Earth's circumference. The Greek mathematician, Eratosthenes (276 BC-194 BC) used this same experiment to enable him to prove the sphericity of the Earth and to measure its circumference.
Join to let your school be part of an exciting international activity!
