El Sol ens proporciona molt\u00edssima energia que podem aprofitar. Tamb\u00e9 han descobert la influ\u00e8ncia de l\u2019efecte hivernacle i del color negre sobre la temperatura. Han demostrat ser uns grans coneixedors de l&#8217;energia.<\/p>\n<p>Llavors s\u2019han dividit en grups de treball per fer diferents activitats. 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><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-13371 alignright\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/10\/IMG_6598.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/10\/IMG_6598.jpg 300w, https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2021\/10\/IMG_6598-200x150.jpg 200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>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 bastant m\u00e9s que l&#8217;olla blanca. &#8220;Aquesta cuina concentra la calor a l&#8217;olla&#8221; ens han comentat. \u00a0 Quin gran descobriment aix\u00f2 de poder cuinar amb el Sol! &#8221;<\/p>\n<p>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 de col\u00b7lectors (sense vidre, amb un vidre i amb doble vidre) per comprovar l\u2019efecte hivernacle. Aix\u00ed han pogut confirmar les seves hip\u00f2tesis. Despr\u00e9s s\u2019han explicat m\u00fatuament el taller que no havien realitzat per completar el torn d\u2019activitats.<\/p>\n<p>Felicitats per les grans descobertes que heu fet!
