Vam observar com les mol\u00e8cules de l&#8217;aigua fan for\u00e7a per estar juntes i, encara fan m\u00e9s for\u00e7a les mol\u00e8cules que es troben a la superf\u00edcie.<\/p>\n<p dir=\"ltr\">La N\u00faria ens va preguntar si una navalla s&#8217;enfonsaria si la posem en l&#8217;aigua o en l&#8217;alcohol. Primer, vam posar l&#8217;aigua en un pot i despr\u00e9s vam posar la navalla, per\u00f2 no es va enfonsar. A continuaci\u00f3, vam posar alcohol (etanol per als cient\u00edfics) al recipient i hi vam posar una navalla. En l&#8217;aigua flotava, per\u00f2 en l&#8217;alcohol no. Aqu\u00ed hem comprovat que la tensi\u00f3 superficial de l&#8217;aigua \u00e9s m\u00e9s alta que la de l&#8217;alcohol.<\/p>\n<p dir=\"ltr\">Despr\u00e9s amb un comptagotes vam veure quina resist\u00e8ncia tenien les dues gotes (alcohol i aigua) i altra vegada la gota de l&#8217;aigua tenia m\u00e9s tensi\u00f3 superficial que la de l&#8217;alcohol.<\/p>\n<p dir=\"ltr\">A continuaci\u00f3, per grups vam posar unes safates amb aigua i pebre. En afegir el sab\u00f3 amb el nostre dit, vam veure com aquest trencava la tensi\u00f3 superficial de l&#8217;aigua i el pebre marxava del sab\u00f3.<\/p>\n<p dir=\"ltr\">Finalment, vam comprovar que la tensi\u00f3 superficial \u00e9s molt forta perqu\u00e8 quan afeg\u00edem monedes al pot d&#8217;aigua semblava que l&#8217;aigua fes for\u00e7a per no caure del recipient.<\/p>\n<p><span
