El segon experiment \u00e9s un volc\u00e0.\u00a0<\/span><\/p>\n

Es tracta d\u2019un experiment amb vinagre i bicarbonat. Simula una erupci\u00f3 volc\u00e0nica aprofitant el despreniment de gas que t\u00e9 lloc en la reacci\u00f3 \u00e0cid-base entre el vinagre i el bicarbonat.\u00a0 <\/span>El vinagre \u00e9s un \u00e0cid i el bicarbonat s\u00f2dic una base. Al barrejar el vinagre amb el bicarbonat t\u00e9 lloc una reacci\u00f3 qu\u00edmica en la que es produeix aigua, sal (acetat de sodi) i gas (di\u00f2xid de carboni). Aquest gas \u00e9s el gas responsable que es formin les bombolles que simulen l’erupci\u00f3 volc\u00e0nica.\u00a0<\/span><\/p>\n

Vam comen\u00e7ar aquest experiment visualitzant un v\u00eddeo on s\u2019explica molt b\u00e9 l\u2019experiment.\u00a0<\/span> (\u00a0<\/span>https:\/\/www.ccma.cat\/tv3\/super3\/dinamiks\/lexperiment-volca-explosiu\/video\/4610111\/<\/span><\/a> ) Una vegada ho van tenir clar, van fer una llista dels materials que necessitaven i, per parelles,\u00a0 van anar a comprar-los. A continuaci\u00f3, van fer dos grups de 5 xiquets i xiquets. <\/span>Cada grup va dissenyar i construir el seu volc\u00e0.\u00a0<\/span>Quan ja els tenien acabats, els van fer erosionar.<\/span><\/p>\n

Cada alumne i alumna va dibuixar el seu volc\u00e0. I, per finalitzar<\/span> van descobrir volcans en altres planetes i en llunes del sistema solar.\u00a0<\/span><\/p>\n
