A l’escola la Draga vam celebrar la Setmana de la Ci\u00e8ncia. A Cicle Mitj\u00e0 v\u00e0rem preparar activitats i tallers i ens vam barrejar 3r i 4t curs.<\/p>\n\n\n\n
El divendres abans vam rebre un v\u00eddeo de la nostra Quimiqueta que ens demanava que treball\u00e9ssim el tema de la llum<\/strong>. Ens va explicar que del Sol ens arriba energia a partir de la radiaci\u00f3 solar que emet part\u00edcules de llum (fotons)<\/strong> pel fet d\u2019estar a temperatura molt alta. Aquestes part\u00edcules es desplacen en totes direccions a la velocitat de la llum (300.000 km\/s) i en l\u00ednia recta, donant lloc al que anomenem raig de llum.<\/p>\n\n\n\n \u00c9s a dir, la llum est\u00e0 feta de boletes molt petites que es diuen fotons. No les veiem,, per\u00f2 veiem qu\u00e8 fan quan xoquen amb les coses. La llum del sol sembla blanca, per\u00f2 en realitat no ho \u00e9s. Un raig de sol \u00e9s la\u00a0suma de set colors: vermell, ataronjat, groc, verd, blau, indi i violeta.Les gotes d\u2019aigua tenen un poder gaireb\u00e9 m\u00e0gic: poden separar la llum del sol\u00a0 en els seus set colors. Ho descobrim en dies que plou i fa sol alhora. Els raigs de sol travessen les gotes d\u2019aigua de la pluja i es dispersen en colors,\u00a0 que van del vermell al violeta.<\/p>\n\n\n\n L\u2019ARC DE SANT MART\u00cd:<\/strong><\/p>\n\n\n\n L\u2019arc de Sant Mart\u00ed surt quan el sol brilla i hi ha gotetes d\u2019aigua a l\u2019aire com despr\u00e9s de la pluja, la llum del sol entra dins les gotes d\u2019aigua i es trenca en molts colors. El disc de Newton \u00e9s una rodona amb tots els colors de l\u2019arc de Sant Mart\u00ed. Abans de girar els preguntem qu\u00e8 creuen que passar\u00e0 quan el girem quan gira molt r\u00e0pid ja no es veuen els colors per separat i sembla que sigui de color blanc A l\u2019arc de Sant Mart\u00ed la llum blanca es separa en colors i en el disc de Newton es tornen a ajuntar.<\/p>\n\n\n\n El que vam fer a Cicle Mitj\u00e0 va ser treballar-ho el dimecres al mat\u00ed amb aquests tallers: A la tarda vam construir un disc de Newton per veure com es transformen els colors en llum blanca.<\/p>\n\n\n\n Podeu veure fotos a l’apartat de 3r i 4t de la nostra web.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" A l’escola la Draga vam celebrar la Setmana de la Ci\u00e8ncia.
