El passat dijous 3 de novembre, la pinya de 4t vam rebre la visita sorpresa d’uns nois i noies de l’INS Moian\u00e8s. Eren 5 alumnes de 1r de Batxillerat Cient\u00edfic, acompanyats per les seves professores. Van venir perqu\u00e8 necessitaven fer un estudi del sistema d’a\u00efllament del so del nou edifici de l’escola, i aix\u00ed poder implementar algunes millores en el seu centre que, segons ens van explicar, est\u00e0 molt mal a\u00efllat.<\/p>\n

Per fer aquestes proves ens van demanar que actu\u00e9ssim com quan treballem individualment, en silenci; com quan treballem en grup, amb una mica de volum i, per \u00faltim, que crid\u00e9ssim ben fort. Totes aquestes proves les vam fer amb la porta oberta i tancada, amb un mesurador de decibels dins i fora l’aula. Va ser genial!<\/p>\n

Per\u00f2 no penseu que aix\u00f2 va ser tot… Com que nosaltres els vam ajudar en la seva investigaci\u00f3 i sabien que a classe estem treballant la Terra i l’univers, ens van plantejar un repte… Vam veure un fragment d’una de les pel\u00b7l\u00edcules de Star Wars<\/em> en el qual hi havia un seguit de naus espacials disparant-se pel mig de l’espai. I ens van preguntar, per una banda, si els l\u00e0sers d’aquelles naus\u00a0 podrien viatjar per l’espai i, per l’altra si seria possible sentir el so d’aquelles naus espacials si pogu\u00e9ssim estar en aquella situaci\u00f3.<\/p>\n

R\u00e0pidament vam deduir que el l\u00e0ser pot viatjar per l’espai perqu\u00e8 \u00e9s una llum i la llum del Sol ens arriba cada dia, per\u00f2 no sab\u00edem si el so podia viatjar de la mateixa manera. Aix\u00ed que per descobrir-ho ens van plantejar 2 experiments: l’oscil\u00b7loscopi i el tel\u00e8fon.<\/p>\n

Gr\u00e0cies a aquests 2 experiments vam descobrir que el so, a m\u00e9s d’un emissor i un receptor, necessita un medi per on circular. En el nostre cas, aquest medi \u00e9s l’aire. Per tant, com que a l’espai no hi ha aire, el so no pot viatjar-hi. Aix\u00ed que, al mig de l’espai, ens seria impossible escoltar el so que fan les naus quan volen, es disparen o exploten… Tot i aix\u00f2, a l’hora de fer una pel\u00b7l\u00edcula d’aquest estil, com\u00a0Star Wars<\/em>, si no se sent\u00eds res mentre unes naus es disparen, seria molt avorrit i, per tant, es permeten saltar-se aquesta llei cient\u00edfica i posar-hi so pel gaudi dels espectadors.<\/p>\n

Repte superat!!! Moltes gr\u00e0cies colla de l’INS Moian\u00e8s, ens heu ajudat molt a seguir aprenent coses d’aquest projecte que estem treballant. Esperem haver-vos ajudat en la vostra investigaci\u00f3, tamb\u00e9, i que ben aviat pugueu millorar el so del vostre institut. Segur que tant vosaltres com els altres alumnes de l’institut podreu aprendre m\u00e9s i millor!<\/p>\n

Fins aviat!<\/p>\n
