Divendres 24 de setembre l’alumnat de la classe “Encantats” de 6\u00e9 de prim\u00e0ria de l\u2019Escola La S\u00ednia<\/strong> de Molins de Rei han fet de ge\u00f2legs\/gues\u00a0 investigant les roques que es troben a les Escletxes del Papiol<\/a>.<\/span><\/p>\n

\"\"Han comen\u00e7at parlant del repte que els hav\u00edem plantejat de com saber si un terreny \u00e9s bo per construir una casa. Es notava que havien treballat el tema i\u00a0 han donat for\u00e7a idees del que calia investigar. Tamb\u00e9 han fet algunes hip\u00f2tesis de com podrien haver-se format les escletxes.<\/span><\/p>\n

Despr\u00e9s de revisar el material necessari per investigar, s’han posat mans a la feina. Primer han observat que les Escletxes es troben en un vessant i han diferenciat dos tipus de materials: un de superior blanquin\u00f3s i un d\u2019inferior vermell\u00f3s.<\/span><\/p>\n

\"\"Per descobrir de quins materials es tractava han fet un seguit de proves en ambdues roques, com comprovar la consist\u00e8ncia, la permeabilitat o veure si reaccionava amb l\u2019\u00e0cid clorh\u00eddric. Han confirmat que el material superior s\u00f3n roques calc\u00e0ries i l\u2019inferior s\u00f3n argiles. <\/span><\/p>\n

Despr\u00e9s d\u2019esmorzar s\u2019han endinsat en 4 escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna.<\/span><\/p>\n

Per concloure han fet una posada en com\u00fa i han dedu\u00eft com s\u2019havien format. Com qu\u00e8 les roques calc\u00e0ries es van degradant a causa de la lleugera acidesa que cont\u00e9 la pluja, durant milions d\u2019anys les esquerdes de les roques s\u2019han anat fent m\u00e9s i m\u00e9s grans fins arribar a permetre a l’aigua arribar a les argiles inferiors. Aquestes esquerdes cada vegada s\u00f3n m\u00e9s amples perqu\u00e8 les argiles fan que les roques calc\u00e0ries llisquin vessant avall.<\/span><\/p>\n

Finalment han explicat la problem\u00e0tica de les cases del Papiol, que tamb\u00e9 es troben afectades per esquerdes a les fa\u00e7anes i han fet d\u2019arquitectes proposant diverses solucions per evitar l\u2019aparici\u00f3 d\u2019aquestes.<\/span><\/p>\n

Un cop acabada la feina i despr\u00e9s de dinar han tornat caminant fins a Molins.<\/span><\/p>\n

Els felicitem per la gran feina realitzada!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
