Avui hem rebut la visita de l\u2019alumnat de 1r i 2n de Batxillerat de l\u2019Institut<\/strong> Francesc Ferrer i Gu\u00e0rdia<\/strong> de Sant Joan Desp\u00ed per fer un estudi limnol\u00f2gic de la riera<\/a> de Vallvidrera a l\u2019al\u00e7ada de Campreci\u00f3s.<\/p>\n

\"\"<\/a>Primer han contextualitzat l\u2019\u00e0rea a estudiar calculant la superf\u00edcie de la conca hidrogr\u00e0fica i esbrinant de quins materials geol\u00f2gics<\/a> est\u00e0 formada. Despr\u00e9s han preparat el material necessari per dur a terme l\u2019estudi de camp dels par\u00e0metres fisicoqu\u00edmics (bi\u00f2top) i de la biodiversitat (biocenosi), per poder determinar la qualitat de l\u2019aigua de la riera!<\/p>\n

A la riera, han recollit les dades per equips (coordenades, temperatures, fond\u00e0ria, velocitat, transpar\u00e8ncia, olor, granulometria…) i han capturat macroinvertebrats aqu\u00e0tics que ens serveixen com a bioindicadors (ef\u00edmera, espiadimonis, limnea, barretet, gamba d\u2019aigua dol\u00e7a, etc). Tamb\u00e9 han valorat l\u2019estat de conservaci\u00f3 de la vegetaci\u00f3 del bosc de ribera.<\/p>\n

\"\"<\/a>Al laboratori han pogut acabar de calcular par\u00e0metres com la duresa, conductivitat, mineralitzaci\u00f3, concentraci\u00f3 de nitrits i fosfats, pH i oxigen dissolt amb l\u2019ajuda dels kits de valoraci\u00f3 Projecte Rius.<\/a><\/p>\n

Han estudiat els macroinvertebrats capturats amb l\u2019ajut de lupes binoculars i fitxes identificatives que determinaven el seu \u00edndex biol\u00f2gic. Amb tota aquesta informaci\u00f3 fisicoqu\u00edmica i biol\u00f2gica han determinat la qualitat de l\u2019aigua en base al protocol IBMWPC<\/a>, que ha donat un resultat mediocre.<\/p>\n

Els alumnes han estat molt participatius i han actuat com a bons cient\u00edfics.<\/p>\n

A m\u00e9s, en acabar tot l\u2019estudi han pogut alliberar sans i estalvis els macroinvertebrats capturats al seu h\u00e0bitat on seguiran el seu cicle de vida!<\/p>\n","protected":false},"excerpt":{"rendered":"
