Els alumnes de 4t hem anat a l’aula de ci\u00e8ncies a crear un Arc de Sant Mart\u00ed.<\/p>\n
MATERIAL: aigua, sucre, colorant alimentari, 4 gots i un tub m\u00e9s alt.<\/p>\n
PROCEDIMENT: emplenem els gots amb aigua. Al got 1 no hi posem res, al got 2 una cullerada de sucre, al got 3 dues cullerades de sucre, al got 4 tres cullerades de sucre.
\nFiquem el colorant a cada got.
\nGot 1: colorant vermell,
\nGot 2: colorant groc,
\nGot 3: colorant blau,
\nGot 4: colorant vermell.
\nAboquem els l\u00edquids, amb molta cura, dins del tub llarg. Primer el l\u00edquid del got 4, despr\u00e9s el del got 3, el del 2 i per \u00faltim el del got 1.
\nObservem com s\u2019ha format un arc de Sant Mart\u00ed i no es barregen els l\u00edquids.<\/p>\n
PER QU\u00c8 PASSA AIX\u00d2? Hem variat la densitat dels l\u00edquids afegint sucre. L\u2019aigua m\u00e9s densa \u00e9s la que
\nt\u00e9 m\u00e9s cullerades de sucre, pesa m\u00e9s i es queda a sota.<\/p>\n
Us hem d’explicar, per\u00f2, que en Lloren\u00e7 va perdre la paci\u00e8ncia i no li va sortir l’experiment. I mira que ho va provar m\u00e9s d’una vegada! Va haver de demanar ajuda a la Sonia. Finalment l’activitat va sortir molt b\u00e9.<\/p>\n
Podeu mirar fotos a l’apartat de 4t de la p\u00e0gina web.<\/p>\n
