A l\u2019optativa “Com funcionen les coses”, l\u2019alumnat ha iniciat un recorregut per la hist\u00f2ria de l\u2019electricitat, combinant coneixement hist\u00f2ric i experimentaci\u00f3 pr\u00e0ctica.
\nFa gaireb\u00e9 2.500 anys, a l\u2019antiga P\u00e8rsia, alguns orfebres haurien utilitzat procediments basats en l\u2019electricitat per fer banys d\u2019or en joies. Aquesta hip\u00f2tesi sorgeix a partir de descobriments arqueol\u00f2gics realitzats cap als anys quaranta del segle XX, que apunten a l\u2019exist\u00e8ncia del que es considera una de les primeres piles de la humanitat.
\nPartint d\u2019aquest context hist\u00f2ric, l\u2019alumnat ha recreat l\u2019experi\u00e8ncia a l\u2019aula: s\u2019han convertit en orfebres i han experimentat amb el xapat de claus amb coure, posant en pr\u00e0ctica conceptes b\u00e0sics d\u2019electricitat i reaccions electroqu\u00edmiques.
\nUna activitat que permet entendre com el coneixement cient\u00edfic evoluciona al llarg del temps i com la ci\u00e8ncia es pot aprendre fent, observant i experimentant.<\/p>\n
