Entre l\u2019alumnat de 5\u00e8 A tamb\u00e9 ens ho hem preguntat i en un primer instant vam pensar que el colorant podia ser el causant.\u00a0<\/span><\/p>\n

Per poder experimentar-ho hem tingut la sort de comptar amb Luciferases, un grup de cient\u00edfiques que ens han portat a l\u2019escola experiments per poder donar resposta a la nostra pregunta.\u00a0<\/span><\/p>\n

El dijous 11 de mar\u00e7 de 2021 la cient\u00edfica i mestra Patr\u00edcia Canut ens ha portat la ci\u00e8ncia a l\u2019aula.<\/span><\/p>\n

 <\/p>\n

En primer lloc, sabeu qu\u00e8 s\u00f3n les Luciferases? S\u00f3n enzims que catalitza l’oxidaci\u00f3 de la luciferina i provoca la producci\u00f3 de llum en organismes vius.<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

Ens ho ha demostrat amb un petit experiment on hem pogut veure una simulaci\u00f3 dins d\u2019una ampolla de vidre.<\/span><\/p>\n

 <\/p>\n

A continuaci\u00f3, hem simulat l\u2019efecte dels focs artificials amb un experiment on hem fet servir sucre, bicarbonat i alcohol per fer uns ous que hem cremat i han produ\u00eft una \u201cserp\u201d.<\/span><\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Finalment, tal i com hav\u00edem descobert, el foc de colors sorgeix de cremar diferents elements. Amb coure, \u00e0cid b\u00f2ric, acetona i sal hem aconseguit fer els diferents recipients per fer els diferents colors.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Ha sigut una experi\u00e8ncia molt enriquidora i agra\u00efm molt a Luciferases i a la Patr\u00edcia per tot el que ens ha ensenyat.<\/p>\n
