Durant dues setmanes, hem rebut l’alumnat de 1r i 2n de Batxillerat de diferents centres de Catalunya al Camp d’Aprenentatge, a Guardiola de Bergued\u00e0.<\/p>\n\n\n\n

Amb ells i elles hem realitzat un estudi exhaustiu de la qualitat del riu Llobregat, aprofitant que ens passa just per davant del camp, afegint-hi la comparativa entre dos punts de mostreig: un abans de la depuradora del poble i un altre despr\u00e9s.<\/p>\n\n\n\n

Aquesta activitat permet a l’alumnat experimentar amb el m\u00e8tode cient\u00edfic a partir d’una situaci\u00f3 d’aprenentatge real, on s\u00f3n ells mateixos els que a partir d’una pregunta inicial, generen unes hip\u00f2tesis, agafen mostres i prenen mesures a camp, i al laboratori executen an\u00e0lisis volum\u00e8trics i colorim\u00e8trics per determinar els par\u00e0metres qu\u00edmics que m\u00e9s influeixen a la qualitat de l’aigua.<\/p>\n\n\n\n

En aquesta activitat ens centrem sobretot en l’an\u00e0lisi qu\u00edmic de l’aigua, ja que \u00e9s una bona oportunitat per l’alumnat de treballar amb material i reactius de laboratori que moltes vegades no tenen a l’abast als centres. A m\u00e9s, hi afegim un altre punt de vista a aquest estudi, i \u00e9s el dels bioindicadors, on a partir de l’observaci\u00f3 i identificaci\u00f3 de determinades esp\u00e8cies de macroinvertebrats, podem donar una mirada m\u00e9s global i exacte de la qualitat de l’aigua del nostre riu. <\/p>\n\n\n\n

Paral\u00b7lelament, se’ls demana que portin una mostra d’aigua de riu d’algun lloc proper al centre, fet que permet veure difer\u00e8ncies significatives moltes vegades respecte l’aigua del Llobregat. Sovint, els resultats els permet reflexionar sobre la necessitat de preservar els ecosistemes fluvials que tenen m\u00e9s propers, que \u00e9s tamb\u00e9 un dels objectius principals de l’activitat. <\/p>\n\n\n\n
