Ara ja coneixem moltes coses com, per exemple, la difer\u00e8ncia entre m\u00e0quines simples i m\u00e0quines compostes o que les m\u00e0quines simples s\u00f3n 6 (la roda, la politja o corriola, el cargol, la falca, la rampa i la palanca), entre altres coses. Tamb\u00e9 hem incorporat vocabulari nou com engranatges, rodes c\u00e8ntriques i exc\u00e8ntriques, pistons, manovella i moltes m\u00e9s. Hem conegut un personatge d&#8217;un c\u00f2mic de fa anys, el TBO, que es dedicava a construir m\u00e0quines incre\u00efbles per\u00f2 sovint molt absurdes. Ha estat divertit saber coses del professor Franz de Copenhage i analitzar els seus invents. Finalment, a partir d&#8217;uns prototips presentats a classe, hem dissenyat la nostra pr\u00f2pia m\u00e0quina amb material reciclat. Capses de cartr\u00f3, fulls de paper, palletes de cartr\u00f3, silicona, pegament, pintura, palets de fusta&#8230; ha estat el material que hem fet servir, b\u00e0sicament, i&#8230; una gran dosi d&#8217;imaginaci\u00f3.<\/p>\n<p style=\"text-align: justify;\">La veritat \u00e9s que ens ha agradat molt fer la nostra pr\u00f2pia andr\u00f2mina i, a m\u00e9s a m\u00e9s, que funcioni perqu\u00e8 durant tot el proc\u00e9s de creaci\u00f3 hem superat reptes i problemes que ens anaven sortint.<\/p>\n<p style=\"text-align: justify;\">Us deixem amb el v\u00eddeo que exemplifica tot el proc\u00e9s i el resultat final. Per cert, dijous passat i amb motiu de la setmana de la ci\u00e8ncia vam tenir la satisfacci\u00f3 d&#8217;exposar les nostres creacions davant tots els familiars que van poder assistir a l&#8217;acte. Estem molt orgullosos de la nostra feina.<\/p>\n<p>&nbsp;<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/J2OcLPzU4OA\" width=\"560\"
