Els alumnes de 4t de l’Escola Amat verd\u00fa de Sant Boi de Llobregat van venir el dies 22 i 23 de mar\u00e7 a investigar la riera de Vallvidrera.
\nHavien fet moltes activitats pr\u00e8vies a l’escola com el cicle de l’aigua i la situaci\u00f3\u00a0de la riera.<\/p>\n

Vam comen\u00e7ar a l’aula amb una pluja d’idees de com investigar la riera i fent un inventari del material que ens endur\u00edem.<\/p>\n

\"5\"<\/a>Un cop a la riera vam analitzar:
\nPrimer les condicions fisicoqu\u00edmiques de l’aigua\u00a0com la temperatura, l’olor, el color, la pres\u00e8ncia d’escuma; tamb\u00e9 van mesurar la fond\u00e0ria i l’amplada.<\/p>\n

En segon lloc vam identificar la vegetaci\u00f3 de ribera m\u00e9s caracter\u00edstica com: el c\u00e0rex, la cua de cavall, l’om i el pl\u00e0tan.<\/p>\n

En tercer lloc vam capturar els animalons que hi viuen i vam netejar la zona d’algunes deixalles que hi havia.\"9\"<\/a><\/p>\n

De tornada al laboratori vam identificar els macroinvertebrats trobats i amb l’ajuda d’unes fitxes vam saber com s’alimenten, com respiren i es desplacen. La fitxa tamb\u00e9 ens\u00a0va dir el color que tenen associat cada animal\u00f3 en funci\u00f3 de com tolera la contaminaci\u00f3.<\/p>\n

Vam acabar l’activitat marcant a la pissarra tots els animals trobats i el seu color de qualitat, aix\u00ed vam saber que la\u00a0qualitat de l’aigua de la riera \u00e9s baixa.
\nEn un dels grups cada parella d’alumnes va poder explicar les caracter\u00edstiques del animal que havia analitzat.<\/p>\n

Vam acabar intentant trobar la manera de no contaminar els espais naturals.<\/p>\n

Van ser uns grups treballadors i unes mestres molt implicades!<\/p>\n

Fins el curs vinent!<\/p>\n
