Aquesta setmana coincidint amb la setmana de la ci\u00e8ncia, aquest curs dedicada a la nanoci\u00e8ncia, tota l’escola hem dedica un dia a fer experiments relacionats amb aquest tema.<\/p>\n

A Educaci\u00f3 infantil ens va arribar una carta d’en NANO que ens va proposar fer uns experiments molt divertits. Aix\u00ed doncs, ens vam barrejar tots els nens i nenes de P3, P4 i P5 i vam dedicar tot el mat\u00ed del dimecres per a portar-los a terme.<\/p>\n

Vam fer descobriments s\u00faper misteriosos i ens va semblar tot una mica m\u00e0gic!!<\/p>\n

Els experiments:<\/p>\n

CAPTUREM UN ARC DE SANT MART\u00cd<\/strong><\/p>\n

Posem esmalt amb aigua i veiem que al posar-hi una cartolina negra capturem un arc de Sant Mart\u00ed.<\/p>\n

L’esmalt s’escampa per damunt la superf\u00edcie de l’aigua en una capa molt fina d’un nan\u00f2metre de gruix i aquesta reflexa la llum en tot el seu aspectre, per aix\u00f2 veiem l’efecte de l’Arc de Sant Mart\u00ed.<\/p>\n

FORMES MISTERIOSES\u00a0<\/strong><\/p>\n

Endevinar formes sense haver vist els objectes.<\/p>\n

Quan toquem un objecte estrany sense veure’l, activem una mena d’esc\u00e0ner mental que fa un reconeixement de l’objecte i intenta identificar-lo. Quan parlem de nanoci\u00e8ncia parlem de part\u00edcules molt i molt petites que requereixen instruments molt espec\u00edfics, per obtenir imatges molt precises del que estem observant.<\/p>\n

Tamb\u00e9 hem vist que hi ha materials que tenen mem\u00f2ria de forma.<\/p>\n

LA SUPERF\u00cdCIE DE CONTACTE IMPORTA<\/strong><\/p>\n

Hem vist que posant dues pastilles efervescents aixafades dins d’una ampolla amb aigua inflen m\u00e9s i m\u00e9s r\u00e0pid un globus que si les posem enteres. Per tant al obtenir part\u00edcules m\u00e9s petites augmenta la superf\u00edcie de contacte i el mateix material en les mateixes condicions actua diferent.<\/p>\n

 <\/p>\n

Vam ser cient\u00edfics per un dia, mireu:<\/p>\n
