<\/a>Un cop a la riera van analitzar algunes\u00a0\u00a0propietats f\u00edsiques i qu\u00edmiques de l’aigua com l’olor, el color, la pres\u00e8ncia d’escuma; tamb\u00e9 van mesurar la fond\u00e0ria i l’amplada. Despr\u00e9s van identificar la vegetaci\u00f3 caracter\u00edstica de ribera i finalment van capturar invertebrats de l’aigua.<\/p>\nUn cop al laboratori, van estudiar amb deteniment els animalons obtinguts i amb l’ajuda de la informaci\u00f3 que hi havia en unes fitxes van saber com s’alimentaven \u00a0i respiraven els animals que anaven identificant. Tamb\u00e9 van deduir la qualitat de l’aigua de la riera mitjan\u00e7ant el m\u00e8tode dels colors que tenen associats cada invertebrat. Van acordar que predominava el groc i que l’aigua de la riera no est\u00e0 prou neta per poder beure d’ella.<\/p>\n
Fins a un altre any!<\/p>\n
