Mat\u00e9riel:\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/h2>\n

Oiseau de balance (en plastique dur), disponible dans le commerce sous forme de produit fini\u00a0<\/span>\u00a0<\/span><\/p>\n

Instructions:\u00a0<\/span>\u00a0<\/span><\/h2>\n
    \n
  • \u00a0\u00a0\u00a0 Placez l’oiseau avec le bout du bec sur un doigt.\u00a0<\/span>\u00a0<\/span><\/li>\n
  • \u00a0\u00a0\u00a0 Laisse l’oiseau se balancer sur le doigt.\u00a0<\/span>\u00a0<\/span><\/li>\n
  • \u00a0\u00a0\u00a0 Fais tourner l’oiseau lentement.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    Observation:\u00a0<\/span><\/h2>\n
      \n
    • L’oiseau ne tombe pas du doigt, que ce soit en se balan\u00e7ant ou en tournant.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Sa position est stable.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Des poids sont cach\u00e9s dans les bouts d’ailes recourb\u00e9s vers le bas, de sorte que le centre de gravit\u00e9 de l’oiseau se trouve nettement en dessous du bout de son bec.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Le point d’appui sur le doigt se trouve donc au-dessus du centre de gravit\u00e9. Cela permet de maintenir un \u00e9quilibre stable.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
