Els alumnes de 6\u00e8 de l‘Escola Pilar Mestres<\/strong> de La Roca del Vall\u00e9s van realitzar el dia 14 de gener l\u2019activitat d\u2019energia solar<\/a>\u00a0 i van comprovar de quina manera la podem aprofitar.
\nDespr\u00e9s d’exposar les seves experi\u00e8ncies amb l’energia solar que havien treballat pr\u00e8viament a l’escola, es van dividir en petits grups i van comen\u00e7ar la feina realitzant dos dels seg\u00fcents tallers i activitats complement\u00e0ries:<\/p>\n

\"\"<\/a>Taller fotovoltaic<\/strong>: mitjan\u00e7ant unes petites plaques fotovoltaiques i altres elements els nens i les nenes van muntar circuits el\u00e8ctrics senzills on van poder experimentar com la llum solar es transforma en electricitat, la qual cosa van demostrar fent girar un petit ventilador.<\/p>\n

Taller d’escalfar aigua<\/strong>: van muntar tres col\u2022lectors solars experimentals diferents per tal de comprovar com l’efecte hivernacle ens permet augmentar la temperatura de l’aigua que van col\u00b7locar dins una m\u00e0nega negra. Van aportar unes noves hip\u00f2tesis sobre la l’efecte que fan les cobertes de pl\u00e0stic transparent en l’escalfament (un col\u00b7lector sense coberta, un amb una coberta propera a la m\u00e0nega i un altre amb la coberta situada m\u00e9s lluny de la m\u00e0nega). Despr\u00e9s van contrastar-les deixant els 3 col\u00b7lectors exposats al Sol. Quin creieu que va aconseguir escalfar m\u00e9s l’aigua?\"\"<\/a><\/p>\n

Taller de cuina solar<\/strong>: mitjan\u00e7ant una cuina solar parab\u00f2lica, els alumnes van elaborar unes pomes al forn amb la calor del Sol. El color negre de l’olla i la concentraci\u00f3 de calor que aconsegueix la parab\u00f2lica els va permetre comprovar l’efic\u00e0cia d’aquesta cuina tant ecol\u00f2gica.<\/p>\n

Al finalitzar l’activitat, tots els alumnes es van explicar entre ells el taller que els hi faltava per completar la feina.<\/p>\n

Tot i el sol esmorte\u00eft que van tenir durant la primera part de l\u2019activitat han estat uns investigadors molt aplicats. Fins a un altre any!<\/p>\n","protected":false},"excerpt":{"rendered":"
