Hola fam\u00edlies!<\/p>\n

Avui a classe hem fet un experiment molt divertit per comprovar que el llevat \u00e9s un \u00e9sser viu.
Hem posat llevat, aigua calenta i sucre dins d\u2019un pot, i hem tapat la boca amb un globus. En un altre pot hem posat aigua i sucre, per\u00f2 sense llevat.
Al cap d\u2019una estona, el globus del primer pot s\u2019ha inflat. El llevat estava treballant!<\/p>\n

Els alumnes han descobert que el llevat s\u00f3n microorganismes que s\u2019alimenten del sucre i produeixen di\u00f2xid de carboni (CO\u2082), el gas que ha fet que el globus s\u2019infl\u00e9s.<\/p>\n

Despr\u00e9s hem relacionat l\u2019experiment amb el pa. Hem apr\u00e8s que, quan fem pa, el llevat tamb\u00e9 produeix gas, i aquest gas forma els foradets que veiem a la molla.
Aix\u00ed hem ent\u00e8s que gr\u00e0cies al llevat el pa \u00e9s esponj\u00f3s i creix quan es cou al forn.<\/p>\n
