Amb els alumnes de segon de batxillerat de l&#8217;Institut Vilatzara de Vilassar de Mar hem fet un estudi basant-nos en el m\u00e8tode cient\u00edfic on, a trav\u00e9s de l&#8217;observaci\u00f3 del paisatge de tardor que ens envolta, hem plantejat diverses hip\u00f2tesis sobre la capacitat fotosint\u00e8tica de les plantes.
