Aprofitant aquesta efem\u00e8ride en Lluc, l&#8217;Adri\u00e0, en Mart\u00ed, en Jan i la Berta, tots alumnes de 2n d&#8217;ESO, han realitzat un experiment englobat dins del projecte Erat\u00f2stenes (https:\/\/eratosthenes.ea.gr\/ ), el qual agrupa uns 6000 centres educatius d&#8217;arreu del m\u00f3n amb un objectiu: mesurar el radi de la Terra. En un primer moment aquest experiment estava pensat per realitzar-se en el centre dins l&#8217;assignatura de matem\u00e0tiques, per\u00f2 el confinament no ha impedit portar-ho a terme. Aquest mat\u00ed a les 13:56h exactes han mesurat l&#8217;ombra que projectava un objecte d&#8217;al\u00e7ada coneguda. A partir d&#8217;aquestes dues dades, utilitzant una senzilla regla de tres, hem pogut calcular plegats el radi de la Terra sense moure&#8217;ns de casa via google Meet. A m\u00e9s, ho han fet amb una precisi\u00f3 incre\u00efble, amb tant sols un error situat entre el 2 i el 6%.
