Following last March’s great success with more than 1100 schools from around the world involved in the activity, the Eratosthenes Experiment will be held again on the 21st of March, 2017 (a day after the spring equinox day)!
The experiment consist in measure with a high 1 meter stick the shadow provided by the Sun. Some simple mathematics can be applied to get the Earth's radius. The technology behind this experiment is to find the local noon (provided by online websites or by using Stellarium) and to measure the distance between schools in the same longitude or one school to the Equator (by using Google Earth).
Once again, do not miss the opportunity to participate in this fascinating international event! Take part through your school by registering at the website with your school’s longitude and latitude. Once you are registered, you will be put in touch with a school from the same longitude with you by the organizing team. Together with your partner school, you will record data, collaborate, calculate the circumference of the Earth and submit the data.
In order to stand a chance to win a scholarship to attend the 2017 European Science Education Academy (ESEA) Summer School in Greece, take a photo of your experiment and submit it until the 14th of April along with your data. More info at: http://eratosthenes.ea.gr/content/photo-contest-march-2017
Please note that the Eratosthenes Experiment official website has been upgraded. From now on, you can create your account and make use of it in order to register your school, submit & store your experiment data to compare them with future data, and upload to the gallery of Eratosthenes website photos from the experiment taking part at your school (or another location).
