Els alumnes de 6\u00e8 de l\u2019Escola Pilar Mestres-Jaume Torrens <\/strong>\u00a0de La Roca del Vall\u00e9s han realitzat el dia \u00a027 \u00a0de febrer una activitat per aprendre diferents maneres d\u2019aprofitar l\u2019energia solar.<\/a><\/p>\n

Han comen\u00e7at compartint les seves idees sobre les diferents radiacions que emet el Sol i amb quines d\u2019aquestes anaven a treballar. Llavors s\u2019han dividit en grups per realitzar dos dels seg\u00fcents tallers:<\/p>\n

\"\"<\/a>Taller fotovoltaic<\/strong>:<\/strong>\u00a0 els nens i les nenes han muntat senzills circuits el\u00e8ctric amb petites plaques fotovoltaiques, que \u00a0li han proporcionat l\u2019energia el\u00e8ctrica necess\u00e0ria per fer funcionar un petit ventilador.<\/p>\n

\"\"<\/a>Taller d\u2019escalfar aigua<\/strong>: en aquest cas han muntat tres col\u00b7lectors solars<\/a> per tal de comprovar l\u2019efecte hivernacle que fan les cobertes de pl\u00e0stic transparent. Han fet tres variants: un col\u00b7lector no tenia coberta, un altre en tenia una i l\u2019altre dues cobertes. Despr\u00e9s d\u2019elaborar diferents hip\u00f2tesis sobre la influ\u00e8ncia de les cobertes, \u00a0han comprovat quin disseny havia incrementat m\u00e9s la temperatura comparant la temperatura de l\u2019aigua al principi i despr\u00e9s de deixar-la uns minuts al Sol dins del col\u00b7lector. Quin creieu que va funcionar millor?<\/p>\n

Taller de cuina solar<\/strong>: per aquest taller els alumnes han aprofitat l\u2019energia t\u00e8rmica del Sol per fer unes pomes al forn, utilitzant una cuina solar parab\u00f2lica. Una vegada ben orientada la parab\u00f2lica solar per tal d\u2019aprofitar al m\u00e0xim els raigs solars, han anat prenent dades de com augmentava la temperatura amb el temps. La concentraci\u00f3 de calor que aconsegueix la parab\u00f2lica sumat al color negre de l\u2019olla, els ha perm\u00e8s menjar unes pomes rostides delicioses per postres.<\/p>\n

Per acabar la sortida, han agafat el rol de professors i professores per explicar el taller que havien fet als companys que havien realitzat un altre taller.<\/p>\n

Han sigut uns investigadors molt aplicats i han pogut comprovar que el Sol ens dona molta energia.<\/p>\n","protected":false},"excerpt":{"rendered":"
