Un invent que ha fet hist\u00f2ria \u00e9s el rellotge de sorra<\/strong>, un objecte molt antic que ens permet mesurar el temps mentre la sorra cau d\u2019un recipient a l\u2019altre.<\/p>\n\n\n\n

Els rellotges de sorra es van comen\u00e7ar a utilitzar sobretot a l\u2019edat mitjana, cap al segle XIV, especialment en vaixells, perqu\u00e8 eren resistents, f\u00e0cils de fer servir i no es feien malb\u00e9 amb la humitat. Tamb\u00e9 es feien servir en tallers, cuines, esgl\u00e9sies i moltes altres activitats on calia controlar intervals de temps de manera senzilla.<\/p>\n\n\n\n

\u00c9s sorprenent com un invent tan simple \u2014dos bulbs de vidre units i una quantitat de sorra fina\u2014 ha ajudat durant segles a mesurar el pas del temps amb precisi\u00f3.<\/p>\n\n\n\n

La colla de 6\u00e8 ha experimentat <\/strong>amb aquest invent. Han observat com cau la sorra, han fet proves i han constru\u00eft el seu propi rellotge de sorra . <\/p>\n\n\n\n

En aquest v\u00eddeo expliquen, pas a pas, com podeu fer un rellotge de sorra<\/strong>.<\/p>\n\n\n\n

Us convidem a mirar el v\u00eddeo i descobrir com, gra a gra, tamb\u00e9 es pot aprendre el temps.<\/p>\n\n\n\n
