Divendres 29 d’abril les classes de 6\u00e8 “Les dones cient\u00edfiques<\/em>“<\/em> de l’Escola 25 de Setembre <\/strong><\/a>de Rub\u00ed\u00a0han investigat les roques que es troben a les Escletxes del Papiol<\/a>.<\/span><\/p>\n

\"\"Per comen\u00e7ar han comentat diversos aspectes del relleu de la zona, com els diferents materials que podien distingir: un de superior de color blanquin\u00f3s i un d\u2019inferior vermell\u00f3s. Seguidament, s<\/span>‘han posat el casc de ge\u00f2leg, i, per grups, han<\/span> revisat el material necessari per investigar: martell de ge\u00f2leg, cinta m\u00e8trica, br\u00faixola i \u00e0cid clorh\u00eddric. Amb tot preparat, han anat a estudiar els dos materials.<\/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

A continuaci\u00f3 s\u2019han endinsat en 3 escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna. Tot i haver tingut un petit incident, ens ho hem passat d’all\u00f2 m\u00e9s b\u00e9!<\/span><\/p>\n

\"\"Per concloure, s’han posat en com\u00fa les dades de tots els grups i han acabat deduint com s’han format Les Escletxes. Han arribat a la seg\u00fcent conclusi\u00f3: com qu\u00e8 les roques calc\u00e0ries es degraden a causa de la lleugera acidesa que cont\u00e9 l’aigua de la pluja, aquest efecte durant milions d\u2019anys ha provocat que les esquerdes de les roques calc\u00e0ries s’anessin fent m\u00e9s grans i profundes fins a permetre a l’aigua<\/span> arribar a les argiles inferiors. Com les argiles s\u00f3n impermeables, l’aigua fa que es tornin toves, aix\u00f2\u00a0 juntament amb el pendent ha provocat que les calc\u00e0ries llisquin vessant avall fins a formar les Escletxes que veiem avui dia. <\/span><\/p>\n

Que valents que heu sigut en entrar a les Escletxes, bona feina. Ens veiem la pr\u00f2xima vegada, qui sap en quin projecte!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
