Just despr\u00e9s de Setmana Santa i, tot i que el temps amena\u00e7ava pluja, els alumnes de segon de batxillerat cient\u00edfic de l’institut Olivar Gran de Figueres acompanyats de les seves professores la Sabina i l’Anna varen venir a fer l’itinerari cient\u00edfic per la Duna Litoral d’Emp\u00faries.<\/p>\n

No plovia, aix\u00ed que tot va anar de perles. Vam comen\u00e7ar amb una introducci\u00f3 breu a l’aula del CdA sobre qu\u00e8 venien a aprendre i com ho far\u00edem. De seguida vam agafar el material de treball i vam anar cap a la platja del Rec; all\u00e0 ens v\u00e0rem posar en cinc estacions de treball. Mentre uns esbrinaven la salinitat del mar, del rec i de l’aiguabarreig amb l’ajut d’un refract\u00f2metre i d’un dens\u00edmetre, un altre grup experimentava el principi d’Arquimedes amb un vaixell de ferro surant al mar; un grup recollia petxines i deixalles i els \u00faltims observaven com es comporta el rec del Mol\u00ed i quina \u00e9s la seva hist\u00f2ria, aix\u00ed com la hist\u00f2ria de la duna litoral. L’activitat en aquest punt es va acabar posant en com\u00fa els resultats, classificant les petxines, reflexionant sobre les deixalles i decidint si l’\u00c0lex havia trobat o no el punt de l’aiguabarreig. Com que la densitat del mar ens va sortir 1020, la del Rec 1002 i la de l’aiguabarreig 1010, podem dir que\u00a0 ho va fer molt b\u00e9; vegeu algunes fotos d’aquesta activitat.<\/p>\n

Aqu\u00ed al costat de la desembocadura del rec v\u00e0rem aprendre que res no \u00e9s el que sembla i que un paisatge tan id\u00edl\u00b7lic pot ser tot menys un paisatge “Natural”.<\/p>\n

El segon punt de treball el vam establir a la platja del Pedrigolet on v\u00e0rem comptar les onades per parlar de temps geol\u00f2gic i erosi\u00f3; tamb\u00e9 v\u00e0rem esbrinar quines roques hi ha a la platja amb l’ajut de l’\u00e0cid clorh\u00eddric i v\u00e0rem parlar dels sediments i la seva granulometria en aquest punt. Finalment l’itinerari es va acabar contemplant el bell arc del Portitxol i especulant si es trencar\u00e0 aviat o encara durar\u00e0 milers d’anys.<\/p>\n

Un dia rod\u00f3 amb molts aprenentatges i sobretot molta natura i aire lliure!<\/p>\n
