    Ens fixem que hi ha una \u201cdutxa amb dues aixetes\u201d, una amb el color blau i l\u2019altre vermell. Obrim el debat i decidim provar qu\u00e8 passa quan obrim cadascuna de les aixetes. Posem aigua a dues ampolles diferents. Una amb aigua de l\u2019aixeta blava i una amb aigua de l\u2019aixeta vermella. Les toquem i ens adonem que la de color blau fa sortir aigua freda i la de color vermell la fa sortir calenta.<\/p>\n

    Parlem de com escalfem l\u2019aigua, i perqu\u00e8 la fem servir. I de com la refredem, i perqu\u00e8 la fem servir. Preparem aigua en \u201ccubiteres\u201d i unes les portem al congelador\u00a0 i les altres a la nevera despr\u00e9s de plantejar-nos qu\u00e8 passaria si …<\/p>\n

    L\u2019endem\u00e0 les anem a buscar i observem qu\u00e8 ha passat en cada cas. A la nevera s\u2019ha refredat molt i al congelador tamb\u00e9 per\u00f2 s\u2019ha posat molt dura. Parlem del gel relacionant-ho amb els gelats i el que utilitzem quan fa calor per refrescar les begudes. Ara ja sabem com podem fer gel!!<\/p>\n

    Tornem a agafar aigua de cada una de les aixetes en dos recipients diferents per saber qu\u00e8 passa quan posem el gel amb aigua freda i amb aigua calenta. Mentre esperem i observem anem fent suposicions del qu\u00e8 creiem que passar\u00e0…<\/p>\n

    Al cap d\u2019una estona apreciem que el gel de l\u2019aigua calenta ha desaparegut i el de l\u2019aigua freda no… Qu\u00e8 ha passat?<\/p>\n

    Resulta que el gel s\u2019ha desfet!! I perqu\u00e8 nom\u00e9s s\u2019ha desfet a l\u2019aigua calenta? …<\/p>\n

    Els proposo que seguin tots a la catifa que tocarem el gel ,el mirarem, l\u2019olorarem … Alguns el tasten i tot.<\/p>\n

    Tot\u00a0 jugant , se\u2019ns mullen les mans.. Qu\u00e8 passa? Un parell d\u2019infants estan\u00a0 fragant el gel al radiador i els fa molta gr\u00e0cia que es faci petit. Un tercer se n\u2019adona que s\u2019estan mullant les mans i fa veure als companys que cauen gotes d\u2019aigua pel radiador… tots ho volen provar!! Se sent una exclamaci\u00f3 \u201cSe est\u00e1 fundiendo!!!\u201d. Si, \u00e9s cert, el gel es font. Demano perqu\u00e8 . I arribem a la conclusi\u00f3 de que com que el radiador est\u00e0 calent el gel es desf\u00e0, com amb l\u2019aigua calenta. I alguns puntualitzen que amb l\u2019aigua freda aix\u00f2 no passa.<\/p>\n

    A l\u2019hora de recollir deixem l\u2019aigua freda amb els gels que no s\u2019han desfet a sobre del radiador mentres esmorzem. A veure qu\u00e8 passa?…<\/p>\n

    Quan tornem del pati un dels nens va directe al radiador i em porta el pot tot sorpr\u00e8s… \u201cel gel ha desaparegut i ara est\u00e0 tot calent!!\u201d<\/p>\n

    Per \u00faltim, proposo fer un gel\u00a0 molt gros. Com ho podr\u00edem fer? Presento diferents materials on posar aigua: cubiteres, safates i gots. A quin recipient \u00a0creieu que farem el gel m\u00e9s gran? I tots trien les safates. N\u2019emplenem dues i les posem al congelador.<\/p>\n

    L\u2019endem\u00e0 les anem a buscar i com que s\u00f3n tan grosses no s\u2019han congelat del tot. La part m\u00e9s externa est\u00e0 dura i molt freda, congelada. Per\u00f2, la part de dins, no s\u2019ha congelat. Podem veure la part de dins l\u00edquida per\u00f2 no la podem tocar… \u00c9s impressionant!!<\/p>\n
