Els alumnes de sis\u00e8 han realitzat una s\u00e8rie d’experiments per explorar les propietats de la llum, aprofundint en conceptes com la composici\u00f3 i descomposici\u00f3 de la llum blanca, l’opacitat i transpar\u00e8ncia dels materials, aix\u00ed com la refracci\u00f3 i reflexi\u00f3.<\/p>\n

Composici\u00f3 i descomposici\u00f3 de la llum blanca
\n<\/strong>A partir del disc de Newton i de la difracci\u00f3 de la llum en un CD, els estudiants han observat com la llum blanca es descompon en els colors de l’arc de Sant Mart\u00ed. Aquest experiment els ha perm\u00e8s entendre que la llum blanca est\u00e0 composta per una barreja de diferents longituds d’ona, cadascuna corresponent a un color espec\u00edfic.<\/p>\n

Opacitat i transpar\u00e8ncia dels materials
\n<\/strong>Els alumnes han investigat com diversos materials afecten el pas de la llum. Han classificat objectes segons la seva capacitat per permetre el pas de la llum, distingint entre materials transparents, transl\u00facids i opacs.<\/p>\n

Refracci\u00f3 i reflexi\u00f3
\n<\/strong>Mitjan\u00e7ant experiments amb aigua i altres mitjans, els estudiants han observat com la llum canvia de direcci\u00f3 en passar d’un medi a un altre (refracci\u00f3) i com es reflecteix en superf\u00edcies llises. Han utilitzat l\u00e0sers i miralls per estudiar aquests fen\u00f2mens, aprofundint en les lleis de la refracci\u00f3 i la reflexi\u00f3, aix\u00ed com en els angles d’incid\u00e8ncia i reflexi\u00f3.<\/p>\n

Aquests experiments han perm\u00e8s als alumnes aplicar els coneixements te\u00f2rics adquirits a l’aula, fomentant la seva curiositat cient\u00edfica i el pensament cr\u00edtic.<\/p>\n
