La setmana passada, els\/les alumnes de 2n.A i 2n.B vam experimentar com un os de pollastre podia perdre la seva duresa al quedar-se sense calci.<\/p>\n
Aix\u00ed doncs, ens vam ajuntar les dues classes a la sala de mestres i vam realitzar l’experiment de forma conjunta. Primer, amb un fregall vam netejar els ossos i despr\u00e9s els vam introdu\u00efr en un pot de vidre ple de vinagre. Al cap de quatre dies, vam obrir el pot i li vam canviar el vinagre. Finalment, a la setmana seg\u00fcent vam tornar a obrir-lo i vam comprovar com els ossos havien perdut la seva duresa i s’havien convertit en ossos de goma. El vinagre havia fet que perdessin tot el calci que els enforteix!!<\/p>\n
