Aquests darrers dies la colla de 6\u00e8 (Pigtown) hem estat experimentant amb diversos tipus de canvis qu\u00edmics. Hem observat qu\u00e8 passava si barrej\u00e0vem diverses subst\u00e0ncies amb o sense pres\u00e8ncia de calor (bicarbonat i vinagre, la cera d’una espelma combinant-se amb l’oxigen de l’aire, \u00e0cid clorh\u00eddric -dilu\u00eft- amb pedres de diferents composicions, una soluci\u00f3 d’aigua amb sucre escalfada fins que l’aigua s’evapori, coca-cola amb mentos…). Hem anotat les nostres observacions en una fitxa i hem explicat qu\u00e8 creiem que havia passat a l’interior d’aquests materials (\u00e0toms i mol\u00b7l\u00e8cules).<\/p>\n

Els darrers dies hem apr\u00e8s tamb\u00e9 diferents t\u00e8cniques de separaci\u00f3 de materials: la filtraci\u00f3, la imantaci\u00f3, la decantaci\u00f3 i l’evaporaci\u00f3.<\/p>\n

Ha estat molt interessant!<\/p>\n
