Hola, som els mitjans petits: Gala, Gisela, Ibulay, Bruna, Odei, Nil, Boi, Ena\u00ef, Jair, Hector, Kai, Nam, Valentina, Alex, Alessandro i Silvia.<\/p>\n

Vam llan\u00e7ar el tap de suro des de damunt d\u2019una cadira i vam veure amb el cron\u00f2metre que trigava 0,55 segons a caure a terra. Aix\u00f2 \u00e9s menys d\u20191 segon i vam fer uns invents per investigar com podem aconseguir que el tap de suro caigui m\u00e9s lentament. Vam fer servir tres t\u00e8cniques diferents: amb globus, com un paracaigudes, enroscant el tap amb un fil. Alguns dels nostres invents van caure m\u00e9s lentament i altres m\u00e9s de pressa i els vam endre\u00e7ar a la xarxa de relacions de la classe.<\/p>\n

En veure que els invents que haviem constru\u00eft amb globus queien a terra molt de pressa, vam investigar quins globus pugen i quins no. Vam descobrir que els globus que inflem amb l\u2019aire de la nostra boca cauen a terra molt de pressa, en canvi vam descobrir que hi ha alguns globus que si que pugen:<\/p>\n

    \n
  1. Els globus d\u2019heli: \u00e9s un tipus de gas que pesa menys que l\u2019aire que hi ha fora del globus i, per aix\u00f2, puja.<\/li>\n
  2. Els globus aerost\u00e0tic: el cremador escalfa l\u2019aire de dins del globus i l\u2019aire calent puja cap a munt, perqu\u00e8 tamb\u00e9 pesa menys que l\u2019aire de fora del globus.<\/li>\n<\/ol>\n

    Fins aviat!<\/p>\n
