A Science els alumnes de 4t estem treballant els materials i les seves propietats. Hem fet hip\u00f2tesis sobre la impermabilitat de diferents materials, la capacitat d’absorb\u00e8ncia de diferents papers i la seva resist\u00e8ncia. Despr\u00e9s ho hem comprovat amb experiments. Ens ha sorpr\u00e9s l’alta resist\u00e8ncia de la cartolina i el seu nom en angl\u00e8s ,que \u00e9s “sugar paper” i aix\u00f2 que no \u00e9s comestible! Tamb\u00e9 ens hem preguntat perqu\u00e8 un foli sembla impermeable si el tensem sobre un got. En el debat hem arribat a la conclusi\u00f3 que \u00e9s perqu\u00e8 t\u00e9 una alta densitat i aix\u00f2 fa que li costi a l’aigua traspassar-lo, per\u00f2 que no \u00e9s impermeable.<\/p>\n\r\n\t
