Over the past week, Year 5 have completed their geography work on Volcanoes and Earthquakes, by building their own, Mount Vesuvius (Pompeii 79AD).
In groups, the children worked together using paper mache, to create the shape of the volcano, painted them and then the best part…
The eruption, which linked in with Science and chemical reactions, by mixing vinegar and bicarbonate of soda.
The acid (Vinegar) and the alkali (bicarbonate of soda), react together producing bubbles of carbon dioxide (CO2). CO2 is released like a pyroclastic flow. A pyroclastic flow moves very fast and is extremely dangerous, whilst lava flows, move slowly and aren’t as much as a threat.
