Mat\u00e9riel:\u00a0<\/span>\u00a0<\/span><\/h2>\n
    \n
  • Bouteille de verre\u00a0<\/span>\u00a0<\/span><\/li>\n
  • battant, par ex. cuill\u00e8re \u00e0 caf\u00e9\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    Instructions:\u00a0<\/span>\u00a0<\/span><\/h2>\n

    Sifflet:\u00a0\u00a0\u00a0<\/strong><\/p>\n

      \n
    • Soufflez dans le goulot de la bouteille jusqu’\u00e0 ce qu’un son apparaisse.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Remplissez la bouteille de diff\u00e9rentes quantit\u00e9s d’eau et \u00e9coutez comment le son se modifie.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Cloche:\u00a0\u00a0\u00a0<\/strong><\/p>\n

        \n
      • Tapez sur la bouteille avec le battant de mani\u00e8re \u00e0 ce qu’un son se fasse entendre.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Cette fois encore, remplissez la bouteille de plus d’eau et \u00e9coutez le son.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n

        Sifflet:\u00a0\u00a0\u00a0\u00a0<\/strong><\/p>\n

        Lorsque l’on souffle dans la bouteille, on entend un son semblable \u00e0 celui d’un sifflet.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

        Plus le niveau d’eau est \u00e9lev\u00e9, plus le son est aigu.\u00a0\u00a0\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

        Cloche:<\/strong>\u00a0\u00a0<\/span>\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

        Si l’on tape sur la bouteille avec la cuill\u00e8re, un son est \u00e9galement produit.\u00a0<\/span>\u00a0<\/span><\/p>\n

        Mais cette fois, la hauteur du son diminue lorsque le niveau d’eau augmente.\u00a0<\/span><\/p>\n","protected":false},"featured_media":1276,"template":"","meta":[],"product_brand":[],"product_cat":[940,949,699],"product_tag":[],"class_list":{"0":"post-1273","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-13-oscillations-ondes","7":"product_cat-16-acoustique","8":"product_cat-a-mecanique","9":"","10":"woocommerce-text-align-left","11":"woocommerce-image-align-center","13":"first","14":"instock","15":"shipping-taxable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product\/1273","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media\/1276"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1273"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1273"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1273"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
