Hem intentat respondre les preguntes de:<\/p>\n<ul>\n<li>quina forma pren l&#8217;energia?<\/li>\n<li>Com es transforma l&#8217;energia?<\/li>\n<li>D&#8217;on\u00a0podem extreure energia?<\/li>\n<li>Quines energies utilitzem a Esterri d&#8217;\u00c0neu?<\/li>\n<\/ul>\n<p>Ho hem fet a trav\u00e9s d&#8217;unes fitxes a on hi havien les diferents formes d&#8217;energia representades. Amb elles hem pogut aprendre quines formes t\u00e9 l&#8217;energia i hem jugat a veure com es pot transformar. Un exemple era veure com de l&#8217;energia el\u00e8ctrica que proporciona un endoll podem acabar obtenir energia t\u00e8rmica o energia de l&#8217;escalfor a partir d&#8217;un radiador. Despr\u00e9s tamb\u00e9 hem constru\u00eft algunes joguines que ens han ajudat a entendre el qu\u00e8 \u00e9s un generador. Hem vist que \u00e9s aquella pe\u00e7a de la nostra joguina que ens ha perm\u00e8s transformar l&#8217;energia mec\u00e0nica (la for\u00e7a del nostre bra\u00e7 o la for\u00e7a del vent) en energia el\u00e8ctrica (que encenia un led) o l&#8217;energia solar en energia mec\u00e0nica per fer rodar un cotxe. Finalment hem anat a fer un vol per Esterri d&#8217;\u00c0neu per identificar quines energies s&#8217;utilitzen al poble i hem reconegut l&#8217;energia de la biomassa (que fa funcionar la calefacci\u00f3 dels espais p\u00fablics del poble), l&#8217;energia hidroel\u00e8ctrica (a Esterri d&#8217;\u00c0neu hi ha una central hidroel\u00e8ctrica que produeix energia), l&#8217;energia solar t\u00e8rmica (hem observat alguna casa amb captadors t\u00e8rmics a les fa\u00e7anes que serveixen per calentar l&#8217;aigua) o l&#8217;energia de combustibles f\u00f2ssils com el gas natural (vam observar dip\u00f2sits de gas a l&#8217;exterior d&#8217;algunes cases que s&#8217;utilitzen per a fer anar la cuina i la calefacci\u00f3). Finalment hem parlar de l&#8217;energia nuclear, tenint en compte que molta part de l&#8217;energia que viatge per les l\u00ednies el\u00e8ctriques que acaben tamb\u00e9 arribant a Esterri prov\u00e9 de l&#8217;energia que es genera a les centrals nuclears com la d&#8217;Asc\u00f3.<\/p>\n<p>Us deixem un recull d&#8217;imatges de l&#8217;activitat que han preparat des de
