L’alumnat de cicle mitj\u00e0 avui hem realitzat un experiment per tal de discriminar quins s\u00f3n els materials conductors i a\u00efllants del fred i la calor.<\/p>\n

Per fer-lo hem posat un gla\u00e7\u00f3 a sobre de diferents materials: una base de fusta, una de porexpan, un pot met\u00e0l\u00b7lic, un plat de cer\u00e0mica i un tap de pl\u00e0stic. Llavors, per grups, hem especulat\u00a0sobre quin material es desfaria m\u00e9s r\u00e0pidament, val a dir que, tres dels cinc grups ho han endevinat.<\/p>\n

Finalment les mestres ens han explicat perqu\u00e8\u00a0sobre certs materials es desfan m\u00e9s de pressa i en d’altres m\u00e9s a poc a poc. Hi ha materials que s\u00f3n conductors, \u00e9s a dir que retenen la temperatura, i n’hi ha d’altres que s\u00f3n a\u00efllants i que per tant la rebutgen. Per explicar-ho han utilitzat exemples pr\u00e0ctics d’objectes que ens trobem a diari i que estan fabricats per materials conductors o a\u00eflllants\u00a0tot depenent de la seva finalitat, com ara les olles o paelles i els estalvis de la cuina.<\/p>\n
