Les\u00a0principals eines\u00a0de treball a les pr\u00e0ctiques de laboratori de Biologia i Geologia de Primer d’ESO s\u00f3n la lupa binocular i el microscopi \u00f2ptic, instruments que ajuden\u00a0als alumnes a observar i a descriure amb detall els elements estructurals del cos dels diferents \u00e9ssers vius. D\u2019aquesta manera, els alumnes aprenen a recon\u00e8ixer\u00a0les caracter\u00edstiques taxon\u00f2miques que permeten distingir i classificar convenientment els organismes estudiats, aix\u00ed com determinar\u00a0les estructures anat\u00f2miques adaptades a les diferents funcions\u00a0que desenvolupen aquests organismes (nutrici\u00f3, reproducci\u00f3 i relaci\u00f3).<\/p>\n

\"\"<\/a><\/p>\n

Els alumnes han d\u2019aprendre a manipular de manera segura aquests delicats instruments \u00f2ptics, a enfocar convenientment l\u2019\u00f2ptica i a calcular els augments, i interpretar la relaci\u00f3 de mides obtinguda. Tamb\u00e9 han d\u2019arribar a ser capa\u00e7os de dibuixar sobre el paper all\u00f2 que estan observant sense que hi hagi distorsions en les proporcions de les estructures reprodu\u00efdes.<\/p>\n

\"\"<\/a><\/p>\n

Tot plegat implica un entrenament que va comen\u00e7ar amb la primera sessi\u00f3 pr\u00e0ctica al laboratori i que continuar\u00e0 durant tot el curs a mesura que vagin estudiant els principals grups d\u2019organismes, especialment els m\u00e9s petits, de cadascun dels 5 regnes (Moneres (bacteris), Protoctistes (protozous i algues), Fongs (llevats, floridures i bolets), Plantes (molses, falgueres, gimnospermes i angiospermes) i Animals (invertebrats, peixos i tetr\u00e0podes).<\/p>\n

\"\"<\/a><\/p>\n

Amb l\u2019objectiu de practicar amb l\u2019\u00fas de la lupa binocular i del microscopi es van proporcionar als alumnes diferents\u00a0materials d\u2019aspecte i textures diversos (una esponja, minerals, paper, teixit… i, per al microscopi, preparacions permanents en l\u00e0mina prima de teixits vegetals i animals, microorganismes, etc.). Amb l\u2019excusa d\u2019observar aquests materials han pogut practicar l\u2019enfocament prec\u00eds amb diferents objectius i a prendre confian\u00e7a en l\u2019\u00fas d\u2019aquests instruments.<\/p>\n

\"\"<\/a><\/p>\n

Per\u00f2 qui, tenint l\u2019oportunitat de fer-ho, no ha posat alguna vegada el dit sobre la platina de la lupa binocular per mirar-se l\u2019ungla o la pell? \u00c9s un cl\u00e0ssic! I no tallarem les ales a l\u2019esperit investigador dels alumnes, oi? Aix\u00ed, els alumnes van dedicar l\u2019hora a observar objectes del laboratori, per\u00f2 tamb\u00e9 van observar dits i ungles; tot sigui perqu\u00e8, quan calgui observar bacteris, protozous, espores, fongs, o insectes, no els calgui dedicar m\u00e9s temps a l\u2019observaci\u00f3 del dit…<\/p>\n

\"\"<\/a><\/p>\n

L\u2018activitat d\u2019observaci\u00f3 de dits i d\u2019ungles va tenir tamb\u00e9 quelcom de molt positiu, i \u00e9s que alguns alumnes van prometre rentar-se b\u00e9 les mans i sota les ungles despr\u00e9s de veure-les augmentades!<\/p>\n","protected":false},"excerpt":{"rendered":"
