Els nens i les nenes de 4t han realitzat un experiment molt interessant per descobrir els pigments que donen color a les plantes. A trav\u00e9s d\u2019una t\u00e8cnica cient\u00edfica anomenada cromatografia<\/strong>, hem pogut observar que dins d\u2019una mateixa fulla hi ha diferents colors amagats.<\/p>\n\n\n\n

Per fer l\u2019experiment hem utilitzat fulles d\u2019espinacs<\/strong> i de col lombarda<\/strong>. Primer vam triturar les fulles per extreure\u2019n el pigment i despr\u00e9s vam posar una petita mostra en una tira de paper de cuina. Tot seguit, vam col\u00b7locar el paper dins d\u2019un recipient amb alcohol.<\/p>\n\n\n\n

A poc a poc, el l\u00edquid va anar pujant pel paper i va arrossegar els pigments de les plantes. Aquest proc\u00e9s va permetre separar els diferents colors que formen part de les fulles. Tothom va poder observar bandes de diversos tons verds, grocs i fins i tot violetes.<\/p>\n\n\n\n

Amb aquest experiment hem apr\u00e8s que el color verd de les plantes prov\u00e9 principalment de la clorofil\u00b7la<\/strong>, per\u00f2 que tamb\u00e9 hi ha altres pigments que normalment no veiem a simple vista.<\/p>\n\n\n\n

Ha estat una experi\u00e8ncia molt enriquidora, ja que els nens i nenes han pogut treballar com aut\u00e8ntics cient\u00edfics: observant, fent hip\u00f2tesis i analitzant els resultats. A m\u00e9s, hem descobert que la ci\u00e8ncia tamb\u00e9 pot ser divertida i plena de sorpreses!<\/p>\n\n\n\n

Continuarem experimentant i aprenent junts!<\/p>\n\n\n\n
