Aquest dimarts 16 de febrer hem estat a l\u2019Escola 25 de Setembre<\/strong> de Rub\u00ed amb els alumnes de les classes 5\u00e8 A i 5\u00e9 D\u00a0 experimentant amb l\u2019energia del nostre estimat Sol<\/a>, tot i que avui no s’ha deixat veure gaire.<\/p>\n

Hem comen\u00e7at el dia fent una petita introducci\u00f3 sobre els diferents tipus de raigs que ens envia el Sol i la seva utilitat. Tamb\u00e9 hem comentat la influ\u00e8ncia de l\u2019efecte hivernacle i del color negre sobre la temperatura. Llavors ens hem dividit en grups de treball per fer diferents tipus d\u2019experiments.<\/p>\n

\"\"Hem vist com les plaques fotovoltaiques converteixen la llum del Sol en electricitat muntant un senzill circuit el\u00e8ctric per fer anar un petit ventilador. Com estava molt ennuvolat, hem aconseguit que el molinet gir\u00e9s utilitzant uns focus de llum sobre les plaques fotovoltaiques. Sembla m\u00e0gia!!<\/p>\n

\"\"Despr\u00e9s han realitzat un dels seg\u00fcents tallers: uns han utilitzat una cuina solar parab\u00f2lica, que concentrant la calor provinent del Sol permet cuinar, per\u00f2 de nou els\u00a0 n\u00favols persistents han impedit cuinar les pomes al forn. Nom\u00e9s hem aconseguit escalfar una mica l’olla de color negre.<\/p>\n

Uns altres han fabricat uns col\u00b7lectors solars i han comprovat com unes m\u00e0negues de color negre escalfaven l\u2019aigua. Tamb\u00e9 han experimentat com funciona l\u2019efecte hivernacle, comprovant que els col\u00b7lectors coberts amb vidre per sobre escalfaven bastant m\u00e9s l\u2019aigua.<\/p>\n

Despr\u00e9s s\u2019han explicat m\u00fatuament el taller que no havien realitzat.<\/p>\n

Han sigut uns grans investigadors solars!<\/p>\n","protected":false},"excerpt":{"rendered":"
