Tamb\u00e9 ens han explicat el que havien descobert respecte la influ\u00e8ncia de l\u2019efecte hivernacle i del color negre sobre la temperatura. Han demostrat sers uns grans coneixedors sobre el tema. Llavors s\u2019han dividit en grups de treball per fer diferents activitats.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-12524 alignleft\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/02\/muntatge-2.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/02\/muntatge-2.jpg 300w, https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/02\/muntatge-2-150x150.jpg 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>Per una banda han vist com les plaques fotovoltaiques converteixen la llum del Sol en electricitat muntant un senzill circuit el\u00e8ctric per fer anar un petit ventilador. Quan han posat les plaques al Sol el molinet ha comen\u00e7at a girar instant\u00e0niament. \u00c9s sensacional el que fan les plaques fotovoltaiques.<\/p>\n<p>Despr\u00e9s han realitzat un dels seg\u00fcents tallers: uns han utilitzat una cuina solar parab\u00f2lica, que permet cuinar concentrant la calor provinent del Sol. Els cuiners solars han preparat una recepta de pomes al forn i han experimentat amb el color de l&#8217;olla per veure quina funcionava millor. Han comprovat que l&#8217;olla negra s&#8217;escalfava el doble que l&#8217;olla blanca. Quin gran descobriment aix\u00f2 de poder cuinar amb el Sol!<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-12525 alignright\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/02\/IMG_4080-300x259.jpg\" alt=\"\" width=\"300\" height=\"259\" \/>Uns altres han fabricat uns col\u00b7lectors solars i han comprovat com les m\u00e0negues de color negre escalfaven l\u2019aigua. Tamb\u00e9 han experimentat diferents variants per veure com funciona l\u2019efecte hivernacle, comprovant que els col\u00b7lectors coberts amb vidre per sobre escalfaven bastant m\u00e9s l\u2019aigua. Aix\u00ed han pogut confirmar les seves hip\u00f2tesis.<\/p>\n<p>Despr\u00e9s s\u2019han explicat m\u00fatuament el taller que no havien realitzat per completar el torn d\u2019activitats.<\/p>\n<p>Felicitats!
