\nVan deduir el nom dels materials inferiors i superiors realitzant diferents tipus d’accions com comprovar la duresa picant amb un martell de ge\u00f2leg, observant la reacci\u00f3 de l’\u00e0cid clorh\u00eddric, observant f\u00f2ssils, impermeabilitat a l’aigua…
\nUn cop identificats el material van prendre mesures a quatre de les esquerdes: amplada, salt, fond\u00e0ria i orientaci\u00f3.

<\/a><\/p>\nAmb totes aquestes dades van deduir com amb el pas del temps, l’acci\u00f3 de l’aigua junt amb la disposici\u00f3 dels materials i inclinaci\u00f3 del terreny han propiciat la formaci\u00f3 de les escletxes actuals.<\/p>\n
Per acabar vam veure la curiosa forma corbada del tronc d’alguns arbres i vam anar fins al castell per veure diferents esquerdes en alguns edificis on tamb\u00e9 van plantejar diferents solucions per mirar de minimitzar l’impacte amb el pas del temps.<\/p>\n
Han estat uns alumnes molt valents!<\/p>\n

Alguns alumnes de 1r i 2n de batxillerat de l’Institut Joaquima Pla i Farreras de Sant Cugat del Vall\u00e8s van fer aquesta activitat de fen\u00f2mens de vessant el divendres 4 de desembre.
