Welcome to the Eratosthenes Experiment platform!
In addition you can
This year the experiment will take place on the 22rd of September, on the autumnal 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.
Schools that register till Monday 12th of September 12:00 CET will receive on Wednesday 14th of September an e-mail with the coordinates of potential matching schools along with the information (email) of their contact persons, so that they can communicate and arrange their match-up during the day of the experiment. Schools that register after the referred date and time above, will receive the same email on Friday16th and Monday 19th of September.
Join today and let your school be part of an exciting international activity!
If you would like to perform the experiment by yourself ion a date other than the 22nd of September, you can use this simulator to find the exact angle from your school to the place where the sun rays are perpendicular to the ground.
