Si deixem caure un carro per una baixada, \u00bfquan aconseguir\u00e0 m\u00e9s velocitat: si va buit o si va carregat de blocs d’acer? Aquesta \u00e9s la pregunta que hem fet als alumnes de primer. Cadasc\u00fa t\u00e9 la seva opini\u00f3 pr\u00e8via,\u00a0 per\u00f2 l’\u00fanica manera de respondre la pregunta \u00e9s fent l’experiment: prenent dades del temps de caiguda amb un cron\u00f2metre i despr\u00e9s analitzant els resultats. \u00c9s el que es coneix com a m\u00e8tode cient\u00edfic.<\/p>\n
Els nostres alumnes ho treballen de forma pr\u00e0ctica al laboratori. L’estudi acaba presentant un informe amb el m\u00e8tode i les conclusions. A m\u00e9s, l’experiment resulta divertit perqu\u00e8: \u00bf a qui no li agrada passar una hora de classe deixant caure a tota velocitat un carro per una rampa?<\/p>\n
Per cert, si voleu saber la resposta,\u00a0 pregunteu als alumnes de primer.<\/p>\n
