Avui gr\u00e0cies a un vaixell que ha portat un company hem fet un experiment molt interessat i hem apr\u00e8s moltes coses.<\/p>\n

La Marta ens ha posat davant de la rotllana una capsa de pl\u00e0stic plena d’aigua, diferents materials de la classe (una pe\u00e7a de pl\u00e0stic amb forats, un bol\u00edgraf, un dinosaure, una pin\u00e7a) i el vaixell fet d’escor\u00e7a d’arbre (suro). Primer hem parlat que era cada cosa i de quins materials estaven fetes. I, despr\u00e9s,\u00a0 ens ha preguntat “Qu\u00e8 creieu que passar\u00e0 si posem aquests objectes dintre la capsa amb aigua?”.<\/p>\n

Primer pens\u00e0vem que la majoria de coses s’enfonsarien, per\u00f2 hem descobert que no era el cas, que tot el que era de pl\u00e0stic surava, que la fusta tamb\u00e9 i el vaixell tamb\u00e9, l’\u00fanica cosa que s’enfonsava era el dinosaure… per\u00f2, si era de pl\u00e0stic com podia enfonsar-se?<\/p>\n

Despr\u00e9s la Marta ens ha proposat que cada un de nosaltres agafem un material diferent de la classe per veure quines coses s’enfonsaven i quines suraven i poder entendre perqu\u00e8 el dinosaure sent de pl\u00e0stic s’enfonsava. I de seguida ens hem engrescat amb la\u00a0 proposta. Hem agafat cotxes de metall, cotxes de pl\u00e0stic, ninots, talladors de plastilina, peces imantades… Mentre an\u00e0vem provant tots els objectes els hem anat classificant entre si suraven o no i hem tret varies conclusions:<\/p>\n

    \n
  1. Les joguines de metall (cotxes) sempre s’enfonsen.<\/li>\n
  2. Els cotxes de pl\u00e0stic com tenen dues barres de metall no acaben de flotar ni d’enfonsar-se.<\/li>\n
  3. Les peces de pl\u00e0stic que tenen un espai d’aire dintre sempre floten.<\/li>\n
  4. Si les joguines de pl\u00e0stic no tenen aquest espai d’aire, llavors no floten.<\/li>\n<\/ol>\n
