Per poder respondre a la pregunta: Com \u00e9s que alguns animals poden caminar sobre l\u2019aigua? L\u2019alumnat de 3r ha realitzat experiments per trobar la resposta.<\/p>\n

El primer experiment consistia en deixar un clip sobre l\u2019aigua sense tocar-la i el segon posar pebre sobre l\u2019aigua i deixar anar una gota de sab\u00f3.<\/p>\n

Abans de comprovar que passava, a cada experiment, els i les alumnes ha fet les seves hip\u00f2tesis. Una vegada fetes, han experimentat i han pogut veure els resultats.<\/p>\n

Hem arribat a la conclusi\u00f3 que les mol\u00e8cules d\u2019aigua estan en contacte entre elles i, per tant, formen una pell que t\u00e9 una certa for\u00e7a anomenada tensi\u00f3 superficial, per aquest motiu el clip i el pebre floten. Tamb\u00e9 hem descobert que el sab\u00f3 \u00e9s capa\u00e7 de trencar aquesta for\u00e7a.<\/p>\n

Finalment hem contestat a la pregunta dient que la tensi\u00f3 superficial de l\u2019aigua \u00e9s la responsable que alguns animals puguin caminar sobre l\u2019aigua.<\/p>\n

Ha sigut una sessi\u00f3 on han gaudit i apr\u00e8s molt!<\/p>\n
