En aquesta \u00faltima sessi\u00f3 hem experimentat amb la pressi\u00f3 de l’aire (pressi\u00f3 atmosf\u00e8rica).\u00a0 Per dur a terme aquest experiment nom\u00e9s ens ha calgut:<\/p>\n
Hem omplert el got d’aigua i hem posat la cartolina a sobre.\u00a0 La mestra ha demanat: “Qu\u00e8 passar\u00e0 si girem el got amb la cartolina a sota?”.\u00a0 La hip\u00f2tesi m\u00e9s generalitzada ha estat que es vessaria tota l’aigua.\u00a0 Per si un cas hem agafat una safata ben fonda per si passava el que els nens i les nenes deien.<\/p>\n
\n
Tots han quedat ben parats quan han vist que la cartolina no queia!! Com podia ser?<\/p>\n
\n
A part d’aigua, qu\u00e8 m\u00e9s hi havia dins del got i que quedava a la part superior?\u00a0 Quan hem hagut identificat els components (i gr\u00e0cies a experiments de l’any passat en els que l’aire hi jugava un paper molt important), alg\u00fa ha dit que era l’aire el que xarrupava fort i feia que no caigu\u00e9s la cartolina.<\/p>\n
I qu\u00e8 passaria si deix\u00e9ssim entrar una mica m\u00e9s d’aire a dins del got mentre est\u00e0 del rev\u00e9s?\u00a0 Doncs aqu\u00ed en teniu la prova del que ha passat.\u00a0 S’ha anat buidant l’aigua i el paper ha entrat a dins del got!<\/p>\n
