L’alumnat de 1r d’ESO que aquest trimestre fa l’optativa de Petites investigacions amb la Marta Cuadros, va participar en el Projecte Rius el dia 5 d’octubre i ens expliquen l’experi\u00e8ncia i tot el que han apr\u00e8s.<\/em>
\n
\nEn qu\u00e8 consisteix aquesta sortida?<\/strong>
\nGrups de voluntaris fan inspeccions a diferents trams de rius de Catalunya per saber el seu estat de salut. Ho promou l\u2019associaci\u00f3 H\u00e0bitat i l\u2019Institut Cartogr\u00e0fic de Catalunya i el nostre institut ja fa anys que hi participa dins del programa d\u2019Escoles Verdes.<\/p>\n

Quantes vegades a l\u2019any es realitza?<\/strong>
\nDues. Una a la primavera i una a la tardor.<\/p>\n

Quins s\u00f3n els rius de la comarca de la Segarra?<\/strong>
\nEl Llobreg\u00f3s, el Si\u00f3, l\u2019Ondara i el Cercavins.<\/p>\n

Quin teniu assignat?<\/strong>
\nL\u2019Ondara, en un tram prop de Granyenella.<\/p>\n

Sempre feu el mateix tram?<\/strong>
\nSi, aix\u00ed es poden comparar les dades.<\/p>\n

A quina conca hidrogr\u00e0fica pertany?<\/strong>
\nA la conca del Segre.<\/p>\n

Quin dia hi heu anat?<\/strong>
\nEl divendres, dia 5 d\u2019octubre.<\/p>\n

Quin tipus de mesures f\u00edsiques heu pr\u00e9s?<\/strong>
\nL\u2019amplada del riu (1,80 m), la fond\u00e0ria de l\u2019aigua (0,02 m.), la temperatura de l\u2019aigua (14\u00baC), la velocitat de l\u2019aigua( 0,02 m\/s ), la transpar\u00e8ncia\u2026
\nPer saber la velocitat cronometrem l\u2019estona que tarda un tap de pl\u00e0stic a recorrer una distancia, dividim la distancia pel temps i sabem la velocitat.<\/p>\n

Portava gaire cabal d\u2019aigua ? Sabeu quan ? Com ho heu calculat ?<\/strong>
\nNo, nom\u00e9s 0\u201972 l\/s. Ho hem calculat multiplicant l\u2019amplada per la fond\u00e0ria i despr\u00e9s multiplicant el resultat per la velocitat i aix\u00ed obtenim el cabal.<\/p>\n

Heu mirat espectes qu\u00edmics? Quins?<\/strong>
\nSi, els nitrats (20 mg\/l), el Ph ( entre 7 i 8), i l\u2019oxigen dissolt ( 4 mg\/l).<\/p>\n

Com ho heu fet ?<\/strong>
\nHem agafat mostres d\u2019aigua del riu en provetes , hi hem aplicat la pastilla de reactiu del color corresponent que ens indicava a les instruccions . Al cap d\u2019uns minuts hem comparat els colors que apareixien a les provetes amb els de les taules de resultats.<\/p>\n

Respecte a l\u2019entorn del riu, quin tipus de vegetaci\u00f3 heu observat?<\/strong>
\nHi havia pocs arbres, nom\u00e9s alguns pollancres, bastant cany\u00eds i alg\u00fan jonc boval . Vegetaci\u00f3 de ribera, per\u00f2 escassa.<\/p>\n

A que es dediquen les terres dels dos marges del riu?<\/strong>
\nAl conreu.<\/p>\n

Com es sap quin \u00e9s el marge esquerre i el marge dret del riu?<\/strong>
\nEt pots orientar posant-te de cara cap on flueix el riu i la teva dreta \u00e9s el marge dret.<\/p>\n

Quin tipus d\u2019animals heu buscat dins el riu? Per qu\u00e8?<\/strong>
\nMacroinvertebrats, perqu\u00e8 alguns d\u2019aquests animalons nom\u00e9s viuen en aig\u00fces netes, d\u2019altres en aig\u00fces no tan netes i aix\u00ed serveixen d\u2019indicadors per saber la salut del riu .<\/p>\n

Com els agaf\u00e0veu? Qu\u00e8 heu trobat ?<\/strong>
\nDispos\u00e0vem de salabrets i hem trobat larves de cranc de riu , algun cuc , un escarabat d\u2019aigua. Quan acabem els tornem a deixar a l\u2019aigua.<\/p>\n

Qu\u00e8 fareu ara amb les dades obtingudes?<\/strong>
\nLes enviarem per internet a l\u2019associaci\u00f3 del Projecte rius perqu\u00e8 puguin servir per a elaborar l\u2019informe general dels rius de Catalunya.<\/p>\n

Com sabran a quin punt del riu us esteu referint ?<\/strong>
\nPerqu\u00e8 hi hem escrit les coordenades que ens va facilitar l\u2019Institut Cartogr\u00e0fic..<\/p>\n

En quin estat heu trobat el riu?<\/strong>
\nHi havia poc cabal per l\u2019\u00e8poca de l\u2019any, tot i que havia plogut dies abans, l\u2019estiu ha estat molt sec i tamb\u00e9 poca biodiversitat . El riu presenta alguns s\u00edmptomes de malaltia.<\/p>\n

Quins alumnes hi heu anat?<\/strong>
\nEls alumnes que aquest trimestre fem l\u2019optativa de petites investigacions.<\/p>\n

Trobeu interessant participar en aquest projecte ?<\/strong>
\nSi, perqu\u00e8 aprenem coses noves i ens ho passem b\u00e9 posant-nos amb les botes dins l\u2019aigua per buscar els invertebrats.<\/p>\n
