\"\"El dimecres 17 de novembre l’alumnat de 1r d’ESO E de l’Institut Olorda<\/strong> de Sant Feliu de Llobregat han realitzat un estudi de les condicions ambientals i de la vegetaci\u00f3 dels vessants de solell i obaga en una zona de la vall de la Rierada.<\/p>\n

Abans d’esmorzar ens han compartit les hip\u00f2tesis de les condicions mediambientals en cada vessant que s’havien plantejat al centre i tamb\u00e9 de les caracter\u00edstiques de les plantes que ens trobar\u00edem i les seves adaptacions en funci\u00f3 de l’escassetat d’aigua o de llum.<\/p>\n

Despr\u00e9s d’esmorzar i per equips han agafat: motxilles i suports i hem anat plegats fins al pont de la Sib\u00e8ria on es hem separat: els grups 1, 2 i 3 han anat cap el vessant de solell i els grups 4, 5 i 6 cap el vessant d’obaga.<\/p>\n

Un cop a cada vessant han recollit les dades\u00a0 tot seguint les instruccions del quadernet i fent funcionar correctament tots els aparells.<\/p>\n

– El term\u00f2metre ha d’estar a un metre del terra.
\n– En l’anem\u00f2metre cal posar-nos en posici\u00f3 ben alta i pressionar i fixar-nos quan marca la velocitat m\u00e9s alta.\"\"
\n– Al psicr\u00f2metre cal mullar primer la veta i despr\u00e9s moure’l com si fos una “carraca”; al cap d’un minut fer la difer\u00e8ncia entre la temperatura del term\u00f2metre en sec i l’humit i amb l’ajuda d’una taula calcular la humitat relativa.
\n– El lux\u00edmetre, cal evitar orientar-lo directament al Sol. Encendre’l i\u00a0 pr\u00e9mer la tecla “hold” per fixar la quantitat de luxs.
\n– Amb la br\u00faixola cal encarar-se a la baixada per saber\u00a0l’orientaci\u00f3 del vessant on ens trobem.<\/p>\n

A la segona part han fet fer un estudi de la vegetaci\u00f3 dels vessants: en una parcel\u00b7la d’uns 100 m2 aproximadament han identificat\u00a0 10 plantes caracter\u00edstiques\u00a0 i tamb\u00e9 han quantificat la seva abund\u00e0ncia.
\nDespr\u00e9s van compartir les dades i van\u00a0verificar les hip\u00f2tesis inicials, que eren for\u00e7a encertades. Tamb\u00e9 van comprovar quines plantes de cada vessant contenen m\u00e9s aigua pesant-les abans i despr\u00e9s de dessecar-les en un forn.<\/p>\n

El programari que han utilitzat per a fer aquesta activitat ha estat elaborat per l’equip docent de Can Santoi i es troba disponible al web:
\n– Programa (excel) per a fer l’inventari de la vegetaci\u00f3 dels vessants<\/a>.
\n– Programa (excel) per a calcular el contingut d’aigua a les fulles<\/a>
\n– Programa (flash) per a fer perfils de vegetaci\u00f3<\/a><\/p>\n

Han estat un grup molt eixerit que han pujat i baixat a peu des de l’estaci\u00f3 de tren de Molins de Rei<\/p>\n

Fins l’any vinent!<\/p>\n","protected":false},"excerpt":{"rendered":"
