Els dies 11 i\u00a0 13 de febrer l\u2019alumnat de 6\u00e8 de prim\u00e0ria de l\u2019Escola La S\u00ednia<\/strong> de Molins de Rei va investigar la formaci\u00f3 de les Escletxes del Papiol<\/a>.<\/p>\n

\"\"<\/a>Per comen\u00e7ar van explicar qu\u00e8 s\u00f3n les escletxes i van fer algunes hip\u00f2tesis de com podrien haver-se format. Van observar que es troben en una vessant i van distingir entre el material superior blanquin\u00f3s (on trobem les escletxes) i l\u2019inferior vermell\u00f3s.<\/p>\n

Per descobrir de quins dos materials es tractava van fer un fer un seguit de proves en ambdues roques, com avaluar la consist\u00e8ncia, la permeabilitat o veure si reaccionava amb l\u2019\u00e0cid clorh\u00eddric. Un cop identificats van confirmar que el material superior on es formaven les escletxes eren roques calc\u00e0ries i l\u2019inferior eren argiles. Llavors es van endinsar dins de 4 escletxes i van mesurar la direcci\u00f3,\u00a0 l\u2019amplada i la profunditat de cadascuna.<\/p>\n

\"\"<\/a>Per concloure, van fer una posada en com\u00fa i van deduir 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. Aquestes esquerdes cada vegada s\u00f3n m\u00e9s amples perqu\u00e8\u00a0 les roques calc\u00e0ries llisquen vessant avall sobre les argiles.<\/p>\n

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

Els alumnes s\u2019ho han passat molt b\u00e9 i han apr\u00e8s molt!<\/p>\n

Tamb\u00e9 han col\u00b7laborat amb la iniciativa Petjada Verda<\/a> recollint brossa que han trobat a la zona.<\/p>\n","protected":false},"excerpt":{"rendered":"
