Els alumnes de l’institut Vallvera, com tots els estudiants d’arreu de Catalunya, es varen veure confinats i sense poder assistir a classe, des del 13 de mar\u00e7 del 2020 fins al final de curs. Escoles i instituts van comen\u00e7ar el curs 20-21 sota l’amena\u00e7a de la pand\u00e8mia de CoVid i els confinaments i a\u00efllaments es van anar repetint, de manera que el nostre alumnat\u00a0 es quedava tancat a casa i reprenia les classes una vegada i una altra.<\/span><\/p>\n

Amb aquesta situaci\u00f3 no \u00e9s d’estranyar que la sortida a Emp\u00faries del dia 3 de desembre, fos esperada amb candeletes i amb gran il\u00b7lusi\u00f3 per als alumnes de batxillerat de l’institut Vallvera de Salt.<\/p>\n

BUSCANT L’AIGUABARREIG<\/figcaption><\/figure>\n

Mentre els alumnes\u00a0 d’humanitats visitaven el jaciment d’Emp\u00faries, els alumnes del cient\u00edfic recorrien les platges d’Emp\u00faries.<\/p>\n

Val a dir que, malgrat les previsions de molta fred i vent, la temperatura va arribar a 14\u00ba i la forta tramuntana del dia anterior va girar cap a una briseta de\u00a0 migjorn, de manera que els alumnes m\u00e9s valents\u00a0 van acabar amb l’aigua fins a mitja cama tot buscant l’aiguabarreig.<\/p>\n

A la platja del Rec, just al costat del Rec del Mol\u00ed,\u00a0 v\u00e0rem repassar la hist\u00f2ria de les baralles del rei Jaume II i el comte d’Emp\u00faries per l’aigua del riu Ter i com aix\u00f2 va comportar el desviament del bra\u00e7 gran, que antigament desembocava just a aquesta platja, cap a l’Estartit, on abans hi desembocava el bra\u00e7 petit del ter (Es-Ter-Tit). Aquesta hist\u00f2ria de 8 segles enrere va modificar per sempre la fesomia del paisatge i va provocar que les dunes avancessin terra endins provocant greus problemes a les granges, camps i vies de comunicaci\u00f3.<\/p>\n

“\u00c9S GREU DOCTOR?”<\/p>\n

Aquesta \u00e9s la pregunta que volem contestar. I ho fem aplicant els nostres coneixements cient\u00edfics de diferents camps del saber: f\u00edsica (onades, gravetat), qu\u00edmica (salinitat), biol\u00f2gica (plantes, petxines), geol\u00f2gica (meteoritzaci\u00f3, roques, minerals).<\/p>\n

Si en voleu saber m\u00e9s, si realment desitgeu saber si \u00e9s greu, pregunteu-ho als alumnes del batxillerat cient\u00edfic de Salt, que van observar, investigar, anotar i deduir. Vegeu les fotos d’aquest magn\u00edfic dia d’investigaci\u00f3 cient\u00edfica a la platja.<\/p>\n
