Une fois les 2 flotteurs immerg\u00e9s dans un aquarium, les \u00e9l\u00e8ves simulent une houle (vague de surface). Le flotteur \u00abhorizontal\u00bb (bateau commun actuel) est plus sensible aux oscillations superficielles de l\u2019eau que le flotteur \u00abvertical\u00bb (Polar POD). L\u2019exp\u00e9rience permet de visualiser la tenue dans l\u2019eau et sa stabilit\u00e9 face \u00e0 la houle. Les ballasts d\u00e9tachables permettent de mettre en \u00e9vidence la fonction essentielle de ces derniers (lest).<\/p>\n\n\n\n<p>Pour que les \u00e9l\u00e8ves se repr\u00e9sentent les courants marins, ils ont men\u00e9 des exp\u00e9riences. Par exemple, dans un aquarium, un \u00e9l\u00e8ve a vers\u00e9 de l&rsquo;eau froide color\u00e9e en bleu et un autre a mis de l&rsquo;eau chaude color\u00e9e en rouge. Apr\u00e8s quelques minutes, les \u00e9l\u00e8ves ont constat\u00e9 que l&rsquo;eau circulait ; l&rsquo;eau froide au-dessus de l&rsquo;eau chaude. Gr\u00e2ce \u00e0 cette manipulation, les CM2 ont compris le ce qu&rsquo;\u00e9taient les courants marins et gr\u00e2ce \u00e0 eux, le Polarpod un bateau vertical peut naviguer \u00e0 la vitesse de 1km\/h !<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"337\" height=\"600\" src=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520530.jpg\" alt=\"\" data-id=\"9259\" data-full-url=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520530.jpg\" data-link=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/2023\/11\/21\/polarpodibus-et-les-cm2\/attachment\/1700566520530\/\" class=\"wp-image-9259\" srcset=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520530.jpg 337w, https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520530-169x300.jpg 169w\" sizes=\"auto, (max-width: 337px) 85vw, 337px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"337\" height=\"600\" src=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520544.jpg\" alt=\"\" data-id=\"9262\" data-full-url=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520544.jpg\" data-link=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/2023\/11\/21\/polarpodibus-et-les-cm2\/attachment\/1700566520544\/\" class=\"wp-image-9262\" srcset=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520544.jpg 337w, https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520544-169x300.jpg 169w\" sizes=\"auto, (max-width: 337px) 85vw, 337px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"337\" height=\"600\" src=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520540.jpg\" alt=\"\" data-id=\"9261\" data-full-url=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520540.jpg\" data-link=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/2023\/11\/21\/polarpodibus-et-les-cm2\/attachment\/1700566520540\/\" class=\"wp-image-9261\" srcset=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520540.jpg 337w, https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520540-169x300.jpg 169w\" sizes=\"auto, (max-width: 337px) 85vw, 337px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"337\" height=\"600\" src=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520536.jpg\" alt=\"\" data-id=\"9260\" data-full-url=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520536.jpg\" data-link=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/2023\/11\/21\/polarpodibus-et-les-cm2\/attachment\/1700566520536\/\" class=\"wp-image-9260\" srcset=\"https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520536.jpg 337w, https:\/\/sitesecoles43.ac-clermont.fr\/0430615k\/wp-content\/uploads\/sites\/16\/2023\/11\/1700566520536-169x300.jpg 169w\" sizes=\"auto, (max-width: 337px) 85vw, 337px\" \/><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p>Les \u00e9l\u00e8ves se sont montr\u00e9s particuli\u00e8rement attentifs et enthousiastes lors de cette activit\u00e9.
