Fa unes setmanes vam estar experimentant amb el concepte de per qu\u00e8 floten els vaixells de metall. Primer vam presentar el personatge d\u2019Arqu\u00edmedes, amb el seu fam\u00f3s principi: \u201c Un cos insoluble totalment o parcialment submergit en un fluid (l\u00edquid o gas) en rep\u00f2s rep una for\u00e7a de baix cap a dalt igual al pes del volum del fluid que desallotja\u201d.
\nEvidentment vam haver-ho d\u2019explicar amb unes paraules m\u00e9s senzilles, que els nens de 5\u00e8 i 6\u00e8 poguessin entendre.
\nDespr\u00e9s de veure uns v\u00eddeos explicatius vam experimentar amb el concepte. Primer vam fer uns vaixells amb paper d\u2019alumini i vam comprovar que podien flotar amb facilitat. M\u00e9s tard vam agafar el vaixell que hav\u00edem fet i vam fer una bola, molt i molt premuda per comprovar com s\u2019enfonsava.
\nPer \u00faltim vam haver de construir uns petits vaixells amb plastilina i passatgers. Aix\u00f2 va costar una mica m\u00e9s, perqu\u00e8 si no estaven ben constru\u00efts, s\u2019enfonsaven.<\/p>\n
