Rowan explore chemistry!

Over the past few weeks Rowan class have been brilliant chemists! They have explored different materials and their properties including whether they conduct or insulate and if they can dissolve. Last week they explored ways to separate materials by sieving, dissolving, filtering and evaporating. Finally, this week they have explored reversible and irreversible changes of state. They loved mixing vinegar and bicarbonate of soda to create carbon dioxide gas! Look what happened to the balloon!
