En aquesta activitat, l\u2019alumnat s\u2019aproxima als processos de conservaci\u00f3<\/strong> dels aliments a partir de l\u2019experimentaci\u00f3 i l\u2019an\u00e0lisi de t\u00e8cniques utilitzades al llarg del temps. A trav\u00e9s de l\u2019observaci\u00f3 i la manipulaci\u00f3, investiga com factors com la temperatura, l\u2019oxigen, la humitat o el medi influeixen en la transformaci\u00f3 i conservaci\u00f3 dels aliments.<\/p>\n

L\u2019activitat inclou l\u2019estudi de processos com la fermentaci\u00f3<\/strong>, el buit o l\u2019acci\u00f3 de microorganismes<\/strong> com les floridures, que permeten comprendre el paper dels \u00e9ssers vius i les condicions ambientals en la conservaci\u00f3 aliment\u00e0ria. Mitjan\u00e7ant l\u2019experimentaci\u00f3, l\u2019alumnat analitza, compara i extreu conclusions sobre diferents t\u00e8cniques de preservaci\u00f3, tant tradicionals com actuals.<\/p>\n

Aquest treball permet connectar coneixement cient\u00edfic i pr\u00e0ctica quotidiana, i reflexionar sobre com les societats han desenvolupat estrat\u00e8gies per conservar els aliments, reduir el malbaratament i adaptar-se a l\u2019entorn. L\u2019activitat posa en valor el coneixement t\u00e8cnic i tradicional associat a la transformaci\u00f3 dels aliments dins el m\u00f3n rural.<\/p>\n

(*) Aquesta activitat s\u2019incorpora per primer cop a la nostra oferta educativa durant el curs 2026-27. Els materials did\u00e0ctics estan en construcci\u00f3, i anirem compartint fotografies a mesura que es vagi implementant.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
