Els nens i nenes de 6\u00e8 hem estat treballant el tema de la mat\u00e8ria i els materials i ho hem fet amb experiments molt xulos que ens han perm\u00e8s veure i entendre millor el qu\u00e8 est\u00e0vem aprenent.<\/p>\n

Primer va, dedicar un mat\u00ed a fer experiments per grups i a explicar-los a la resta de la classe. N’hi va haver alguns de molt interessants.<\/p>\n

Vam aprendre a mesurar masses i volums per calcular la densitat dels cossos, per\u00f2 tamb\u00e9 vam estar fent mescles de tota mena per comprovar si eren homog\u00e8nies o heterog\u00e8nies. Vam poder comprovar que la sorra de l’hort \u00e9s m\u00e9s permeable que la del pati i vam estar separant diferents tipus de materials amb els m\u00e8todes de la imantaci\u00f3 i la filtraci\u00f3.<\/p>\n

Alguns dels m\u00e9s espectaculars van ser uns forats que vam fer a una bossa de pl\u00e0stic plena d’aigua amb llapis de colors, ja que vam poder comprovar que l’aigua no sortia, tot i tenir forats!!<\/p>\n

Tamb\u00e9 vam omplir un got d’aigua i, despr\u00e9s de posar-hi un tros de cart\u00f3 a sota li vam fer la volta i vam veure que no queia l’aigua!! Era m\u00e0gia!!!<\/p>\n

Vam comprovar<\/span> que existeix un fluid que es diu NO NEWTONI\u00c0, que es fa barrejant maizena i aigua de manera que si li dones un cop \u00e9s molt dur, per\u00f2 que si el toques \u00e9s l\u00edquid. Va ser superxulo!<\/span><\/p>\n

I vam veure com podem crear ous saltarins, ja que vam deixar dos dies un ou submergit en vinagre, com que l’\u00e0cid ac\u00e8tic es va menjar el carbonat calci de la closca, va quedar sense res, tornant-se tou i “ballar\u00ed”.<\/p>\n

A m\u00e9s tamb\u00e9 van venir la Fede i el Jordi de LABCLUB a fer-nos un taller sobre la import\u00e0ncia de la qu\u00edmica en el nostre entorn. Ens van parlar del pH i de les subst\u00e0ncies \u00e0cides i b\u00e0siques. A partir d’aqu\u00ed vam poder comprovar el pH de diferents mescles.<\/p>\n

El primer que ens van donar va ser col llombarda bullida amb aigua que va donar un pH de 7, aproximadament, aix\u00ed que neutre.<\/p>\n

Despr\u00e9s vam tirar parts d’aquesta aigua lilosa, que era la col llombarda, a diferents pots i a dins de cadascun hi llan\u00e7\u00e0vem diferents subst\u00e0ncies que ells ens donaven com: suc de llimona, sab\u00f3, aigua destil\u00b7lada, bicarbonat de sodi i vinagre.<\/p>\n

Vam comprovar que amb el suc de llimona es tornava d’un color de pH m\u00e9s \u00e0cid (taronja) i, en canvi, amb el sab\u00f3 es tornava m\u00e9s b\u00e0sic (blav\u00f3s).<\/p>\n

Amb el bicarbonat feia una reacci\u00f3 que desprenia gas i, per tant, sortia espuma quan el barrej\u00e0vem.<\/p>\n

Ens han agradat molt tots aquests experiments!!!<\/p>\n
