La trigonometria \u00e9s la part de la matem\u00e0tica que s’encarrega de l’estudi i la mesura dels triangles, les relacions entre els seus angles i costats, i les seves funcions o raons: sinus, cosinus, tangent… Una vegada tractat aquest saber amb l\u2019alumnat de 4t d’ESO, despr\u00e9s de veure i resoldre exemples i problemes a l’aula, arriba el moment d’experimentar aquests coneixement d\u2019una manera m\u00e9s pr\u00e0ctica: amb un clin\u00f2metre! Saps qu\u00e8 \u00e9s? Un clin\u00f2metre, tamb\u00e9 conegut com a declin\u00f2metre o inclin\u00f2metre, \u00e9s un instrument que mesura els pendents verticals, generalment l\u2019angle format entre el terra o l\u2019observador i un objecte alt. Hi ha dos m\u00e8todes per tal de realitzar el teu propi clin\u00f2metre:<\/p>\n

    \n
  1. Clin\u00f2metre simple o d\u2019angle fix: requereix molt d\u2019espai per caminar d\u2019una banda a l\u2019altra quan es mesura un objecte.<\/li>\n
  2. Clin\u00f2metre fet amb un transportador: et permet realitzar el mesurament mentre est\u00e0s dret en un sol lloc i \u00e9s una versi\u00f3 f\u00e0cil que s\u2019utilitza en l\u2019astronomia, la topografia, l\u2019enginyeria i la silvicultura.<\/li>\n<\/ol>\n

    L’alumnat, per parelles, ha constru\u00eft el seu propi clin\u00f2metre a partir d\u2019un transportador i, seguidament, hem baixat al pati de l\u2019Institut per mesurar l\u2019al\u00e7ada dels diferents objectes m\u00e9s alts: arbres, cistelles de b\u00e0squet, el propi edifici…
    \nEncara que les mesures no s\u00f3n del tot precises, s\u2019ho han passat d\u2019all\u00f2 m\u00e9s b\u00e9 comprovant la vessant pr\u00e0ctica de la trigonometria amb un material senzill que han constru\u00eft ells mateixa.<\/p>\n

    Continuaran mesurant amb aquest m\u00e8tode els diferents edificis d\u2019all\u00e0 on vagin?<\/p>\n
