A l’assignatura de qu\u00edmica i amb els alumnes de 1r de Batxillerat hem fet una proposta de recerca per trobar el millor rendiment en el creixement d\u2019un cristall a partir d\u2019una llavor.<\/p>\n

Hip\u00f2tesi<\/em><\/p>\n

El motiu pel qual es proposa aquest experiment es degut a que hem observat que en totes les cristal\u00b7litzacions on hem fet cr\u00e9ixer el primer cristall aprofitant les aig\u00fces mares,\u00a0 el cristall ha crescut molt poc seguint les especificacions que dona \u201cTriana\u201d , pensem que \u201cpotser\u201d que la concentraci\u00f3 proposada no \u00e9s prou sobresaturada. Per investigar aquesta hip\u00f2tesi hem proposat els quatre experiments que es mostren a continuaci\u00f3:<\/p>\n\n\n\n\n\n\n\n
