Seguint el <\/span>m\u00e8tode cient\u00edfic<\/b>, primer hem fet hip\u00f2tesis sobre qu\u00e8 podria passar, hem conversat i compartit idees. A continuaci\u00f3, hem dut a terme l\u2019experiment i hem dedicat temps a l\u2019observaci\u00f3 directa per analitzar els canvis. Finalment, hem posat en com\u00fa les nostres conclusions.<\/span><\/p>\n

A la classe del Fluor, hem volgut entendre la import\u00e0ncia de la protecci\u00f3 de les dents amb pasta amb fluor. Per fer-ho, hem experimentat amb <\/span>closques d\u2019ou<\/b>, ja que tenen una composici\u00f3 similar a l\u2019esmalt dental. Les hem submergit en diferents l\u00edquids \u2014<\/span>aigua, vinagre i colorant verd<\/b>\u2014 per observar com reaccionen i veure quin efecte tenen sobre la seva superf\u00edcie.<\/span><\/p>\n

A la classe del Iode, hem volgut experimentar amb els colors de la <\/span>povidona iodada<\/b>, un antis\u00e8ptic per a la pell que cont\u00e9 una petita part de<\/span> iode<\/b>. Primerament, l\u2019hem dilu\u00eft amb aigua i ens hem adonat que, depenent de la quantitat que en pos\u00e0vem, el to dels colors era diferent: blau fort o fluix, lila, rosat, marr\u00f3, etc. La nostra sorpresa ha estat que, al cap d\u2019unes hores, la dissoluci\u00f3 s\u2019havia tornat transparent… i els nostres dibuixos havien desaparegut!<\/span><\/p>\n

Aqu\u00ed us deixem algunes fotos dels experiments<\/a> perqu\u00e8 pugueu veure el proc\u00e9s i els resultats! <\/span>\ud83e\uddea\ud83d\udd2c\u2728<\/span><\/p>\n
