En un dels tallers hem <strong>cuinat pomes al forn amb l&#8217;escalfor del sol<\/strong> gr\u00e0cies a una cuina solar parab\u00f2lica<strong>,<\/strong> un estri semicircular que concentra la calor al centre. Hem fet dos proves, una amb una <strong>olla negre<\/strong> i una altra amb una altra <strong>olla igual per\u00f2 blanca<\/strong>. Hem volgut experimentar quina permetia coure millor les pomes que hem preparat al forn. Els resultats obtinguts han coincidit amb les <strong>hip\u00f2tesis<\/strong> que els propis alumnes han fet Hem obtingut uns 70 \u00baC amb l&#8217;olla blanca i m\u00e9s de 80\u00baC amb la negre.<\/p>\n<p>Un segon taller ha consistit en muntar unes <strong>col\u00b7lectors solars<\/strong> <strong>per a escalfar aigua potable<\/strong>. S\u00f3n de carcassa de fusta amb una coberta transparent, i al seu interior, hi hem posat una m\u00e0nega que pr\u00e8viament hem emplenat amb l&#8217;aigua. Hem experimentat amb tres col\u00b7lectors iguals, per\u00f2 un d\u2019ells l\u2019hem deixat sense coberta de vidre, l\u2019altre amb un vidre i el tercer amb dos. Per qu\u00e8 ho hem provat? Per veure l\u2019efecte de cobrir o no cobrir les m\u00e0negues negres del seu interior. Hem comprovat que ha funcionat millor el col\u00b7lector solar amb dos vidres.<\/p>\n<p>Avui ha fet molta calor i \u00e9s probable que els dos vidres hagi afavorit que la calor es guardi millor al seu interior es guardi millor al seu interior.<img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-15114\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/06\/IMG_20220602_115930_p-1-300x167.jpg\" alt=\"\" width=\"374\" height=\"208\" srcset=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/06\/IMG_20220602_115930_p-1-300x167.jpg 300w, https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/06\/IMG_20220602_115930_p-1-768x428.jpg 768w, https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2022\/06\/IMG_20220602_115930_p-1.jpg 1000w\" sizes=\"auto, (max-width: 374px) 100vw, 374px\" \/><\/p>\n<p>En el tercer taller hem provat com la placa fotovoltaica <strong>transforma la llum solar amb corrent el\u00e8ctric<\/strong> i hem fet funcionar un <strong>ventilador solar.<\/strong> Durant el muntatge hem comprovat que el corrent el\u00e8ctric necessita circular pels cables conductors, i posant un interruptor en mode \u201ccircuit obert\u201d, hem descobert que el ventilador no funciona perqu\u00e8 els cables deixen d\u2019estar en contacte.
