La setmana del 10 al 17 de novembre vam celebrar la Setmana de la ci\u00e8ncia a la nostra escola.<\/p>\n
L’\u00faltim dia, ens vam reunir tots per ensenyar-nos els experiments que vam estar treballant durant tota aquesta setmana.<\/p>\n
Els alumnes d’infantil ens van explicar com diferents objectes poden absorbir l’aigua i altre no. Un dels m\u00e9s interessants va ser quan ens van ensenyar una pinya. Ens van dir que uns dies abans l’havien posat en aigua i quan ens la van ensenyar, estava la pinya tancada. Durant els seg\u00fcents dies estaran observant si, quan s’assequi, es torna a obrir.<\/p>\n
Els alumnes de cicle inicial van fer dos volcans amb plastilina per explicar-nos com erupcionen. Primer, van posar una pastilla de menta (Mentos) i despr\u00e9s hi van tirar Coca-cola. Vam poder veure com el l\u00edquid sortia amb for\u00e7a, com en una erupci\u00f3 de veritat.<\/p>\n
Els alumnes de cicle mitj\u00e0 ens van ensenyar com hi veu el nostre ull. Resulta que els ulls funcionen com una c\u00e0mera fotogr\u00e0fica senzilla. La lent del cristal\u00b7l\u00ed forma a la retina una imatge invertida dels objectes que enfoca. I quan la informaci\u00f3 arriba al cervell a trav\u00e9s dels nervis \u00f2ptics, aquest la interpreta correctament.<\/p>\n
Per demostrar-ho, van fer 3 experiments.<\/p>\n
En el primer, van fer passar llum per un forat petit on hi havia una lletra dibuixada. Davant hi havia una llanterna i despr\u00e9s una peixera plena d’aigua. Vam poder oberservar perfectament la lletra invertida en la paret.<\/p>\n
En el segon, van tapar una llauna de converva buida amb paper vegetal. A l’altre cant\u00f3, hi van fer un forat petit. Llavors, van posar la llauna al mig d’una cartolina negra de les grans. Quan mir\u00e0vem per la part on hi havia el paper vegetal, vam poder veure com una silueta tota negra de la persona que ten\u00edem davant, per\u00f2 la v\u00e8iem invertida.<\/p>\n
I el tercer, van agafar una caixa de cartr\u00f3 i la van forrar tota de cartolina negra. A dins hi van posar un foli blanc i en el sentit contrari hi van fer un petit forat. En principi s’havia de veure una imatge invertida, per\u00f2 potser perqu\u00e8 hi havia poca llum, no ho vam poder veure molt clar.<\/p>\n
I els alumnes de cicle superior van estar treballant els aparells de cos hum\u00e0. Per aquest motiu, van portar organs d’animals i van estar observant-los. Un dels que m\u00e9s va agradar va ser inflar uns pulmons!!<\/p>\n
Va ser una setmana molt interessant on tots hem apr\u00e8s moltes coses noves.<\/p>\n","protected":false},"excerpt":{"rendered":"
