Aquesta tarda els alumnes de cicle mitj\u00e0 hem iniciat el projecte d’experimentaci\u00f3.<\/p>\n

Hem iniciat la sessi\u00f3 a l’aula de quart on ens hem organitzat per grups. Llavors, l’Alba i la Laura ens han mostrat\u00a0com havien fet entrar un ou dur dins una ampolla i ens han preguntat de quina manera cr\u00e8iem que ho havien aconseguit. Hem pensat possibles respostes i les hem anat presentat.\u00a0Per comprovar quina era l’encertada, hem seguit els passos que ens han indicat les mestres; encendre una espelma o paper de diari, posar-ho dins l’ampolla i tapar l’obertura amb l’ou dur. Poc a poc hem observat com l’ou queia dins.<\/p>\n

Ens hem preguntat quina era l’explicaci\u00f3 del proc\u00e8s, i val a dir que un alumne de tercer l’ha aconseguit deduir. L’oxigen de dins l’ampolla es consumeix, l’ou dur no permet entrar m\u00e9s aire i la pressi\u00f3 de l’interior de l’ampolla disminueix. Fins que finalment l’ou, amb la for\u00e7a de l’aire de l’exterior, acaba a l’interior del recipient.<\/p>\n

Per acabar, l’Alba ens ha explicat un conte molt original que ha acabat amb una efecte molt bonic a l’aire. Nom\u00e9s ha utilitzat un filtre de te, us imagineu com ho ha pogut realitzar?<\/p>\n
