Als alumnes de Batxillerat de l’institut Alexandre Deulofeu de Figueres no els ha importat la fred que ha comen\u00e7at a fer, gaireb\u00e9 sobtadament, aquest inici de novembre.<\/p>\n

A finals d’octubre ten\u00edem temperatures d’estiu, la gent anava en m\u00e0niga curta i molts es banyaven encara a la platja. Est\u00e0vem esperant que arrib\u00e9s la tardor, amb les seves pluges, temperatures un xic m\u00e9s suaus i molts bolets al bosc. Per\u00f2 la paraula TARDOR potser aviat l’haurem d’esborrar del diccionari; ha comen\u00e7at a fer fred, ha nevat al Pirineu,\u00a0 les temperatures han baixat m\u00e9s de 10 graus i s’ha posat a bufar una tramuntana i un gregal que fan dif\u00edcils les activitats arran de mar.<\/p>\n

Tot i aix\u00ed, el 2 de novembre van venir els alumnes del batxillerat cient\u00edfic del Deulofeu a fer l’itinerari per la duna d’Emp\u00faries. Vam fer una introducci\u00f3 a l’aula, tot esperant que les temperatures fossin m\u00e9s amables, i cap a les 10 vam anar cap a la platja del Rec. Al costat del Rec del Mol\u00ed vam establir les nostres estacions de treball:<\/p>\n

    \n
  1. Hist\u00f2ria de la duna d’Emp\u00faries<\/li>\n
  2. Salinitat amb refract\u00f2metre<\/li>\n
  3. Salinitat amb dens\u00edmetre<\/li>\n
  4. Flotaci\u00f3 i principi d’Arquimedes<\/li>\n
  5. Temperatura i transpar\u00e8ncia de l’aigua<\/li>\n
  6. Recol\u00b7lecci\u00f3 de curculles i recollida de deixalles<\/li>\n<\/ol>\n

    Tots els alumnes van passar per totes les estacions, llavors vam fer una posada en com\u00fa dels resultats, i vam intentar treure conclusions i veure si hav\u00edem trobat l’aiguabarreig; aquest cop no hi va haver\u00a0 sort i l’aigua del suposat punt mig entre rec i mar ens va donar una salinitat massa baixa, propera a l’aigua dol\u00e7a. Vam poder deduir que l’aiguabarreig era for\u00e7a endins del mar, perqu\u00e8 la desembocadura es comportava aquest dia com un veritable Delta.<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    Tamb\u00e9 vam classificar les curculles. Despr\u00e9s d’una breu pausa per esmorzar vam anar al Pedrigolet a veure i entendre els processos c\u00e0rstics i la formaci\u00f3 de la cala.<\/p>\n

    \"\"<\/p>\n

    \"\"<\/p>\n

    Finalment davant del Portitxol vam reflexionar sobre la perillositat que caigui el Portitxol i el risc que aix\u00f2 suposaria.<\/p>\n
