Volcanoes

This week Year 6 students learnt about volcanoes. They explored the two most common types; stratovolcanoes and shield volcanoes and then created their own stratovolcano using clay. Each group used bicarbonate soda and vinegar to erupt their volcanoes.

As a class we discussed the chemical reaction and what created the bubbly reaction. The students discovered the carbonic acid is unstable and breaks down into liquid water and carbon dioxide as a gas, causing the ‘build up’ of pressure. The carbon dioxide rises, causing the bubbly reaction.
