A Real Challenge through Eratosthenes Project 2023 by Gabriela Mirela Jugar simple vertical stick , preferably of identical height to simplify comparisons of shadow measurements . It was not necessary either for one of the two partners to be positioned on the tropic of Cancer . It needed only be located at a distinctly different latitude to the other .
The schools involved in this project belong to 19 countries from 4 continents : Europe ( 10 ), Africa ( 1 ), America ( 5 ) and Asia ( 3 ). The 10 European countries are : Greece , France , Serbia , Moldova , Albania , Spain , Germany , North Macedonia , Malta and Romania . Tunisia is the African country . The 5 American countries represented in this project are : Colombia , Argentina , Brazil , Puerto Rico and the USA . The 3 countries from Asia are : Turkey , Vietnam and India .
The Eratosthenes 2023 project was a real challenge for us , working together with many schools around the world . For the work in this great team , the founders created 8 pages : 1 ) Homepage ; 2 ) Schools ; 3 ) Experimental activities ; 4 ) Measures ; 5 ) Astronomical events ; 6 ) Use of ICT ; 7 ) Evaluations ; 8 ) Dissemination . The Home pages refers to a ) Historical experiment and b ) Collaborative measurement .
This project is based on scientific collaboration . Each school needs the measurement of a partner school to obtain the final result . In Historical experiment it is shown how Eratosthenes measured the circumference of the Earth . In Collaborative measure is presented how 2 partner schools calculate the circumference of the Earth .
We conducted this experiment paired with another class ( whose particulars were forwarding to us ) but we were not need either an obelisk or a well . All we each needed was a
The 6 experimental activities suggested by the project founders are : 1 ) Parallelism of solar rays ; 2 ) Solar noon ; 3 ) Curve of the Earth ; 4 ) Angle of the sun ; 5 ) Alternate interior angles and 6 ) Verticality Horizontality . The concept of parallel rays and divergent rays , in relation to the light source , is necessary to validate hypothesis 2 of Eratosthenes . Our pupils drew the sunrays and edited a Gif animated . All the measures were synchronized at local solar noon . The aim was to identify the shortest
