Els alumnes de 4t ESO de l\u2019Institut Joan Bosc\u00e0<\/strong> de Barcelona han estat el dia 8 de maig investigant l’ecosistema de la riera de Vallvidrera al voltant de Can Santoi.<\/p>\n

S’ha fet una breu introducci\u00f3 de la zona on s’ubica la riera per tal de con\u00e8ixer la zona de treball. Seguidament han aportat idees de que podrien investigar, tant en relaci\u00f3 amb els \u00e9ssers vius (biocenosi) com en relaci\u00f3 al medi f\u00edsic (bi\u00f2top).<\/p>\n

\"\"<\/a>S\u2019han dividit en petits grups de treball i han revisat el material necessari pel treball de camp.<\/p>\n

Han anat fins la riera a la zona de la font de l\u2019arbre caigut i han comen\u00e7at el treball de camp fent mesures de par\u00e0metres ambientals com: temperatures de l\u2019aire i \u00a0de l’aigua, la qualitat de l’aigua ( a partir de l\u2019olor, color i pres\u00e8ncia d\u2019escuma). Tamb\u00e9 han calculat la velocitat mitjana del corrent i la fond\u00e0ria de la riera en seccions. Amb aquestes dades posteriorment podran calcular el cabal fent servir els programes de suport<\/a> disponibles al web de Can Santoi. Tamb\u00e9 han agafat mostres d\u2019aigua per mesurar al laboratori el pH, concentraci\u00f3 de nitrats i concentraci\u00f3 d\u2019 oxigen dissolt. Aquestes an\u00e0lisi formaran part de la campanya d\u2019inspecci\u00f3 de primavera del Projecte Rius.<\/a><\/p>\n

\"\"<\/a>Posteriorment han reconegut diverses plantes que formen el bosc de ribera que envolta la riera i finalment han capturat invertebrats aqu\u00e0tics.<\/p>\n

Un cop al laboratori han utilitzat la lupa binocular per veure amb m\u00e9s detall les caracter\u00edstiques anat\u00f2miques dels macroinvertebrats capturats. Amb l\u2019ajut de fitxes de suport han pogut identificar totes les esp\u00e8cies, descobrir caracter\u00edstiques de les diverses esp\u00e8cies i esbrinar el seu \u00edndex biol\u00f2gic.<\/p>\n

Amb totes les seves investigacions han descobert en quin estat de conservaci\u00f3 es troba la riera. Posteriorment s\u2019han tornat a alliberar tots els animalons a la riera sans i estalvis.<\/p>\n

Felicitats perqu\u00e8 han gaudit investigant i amb la seva feina han col\u00b7laborat amb el Projecte Rius.<\/p>\n","protected":false},"excerpt":{"rendered":"
