Vicious Volcanoes

Year 3 experimented with a Science project to learn about chemical reactions and what happens when a volcano erupts. They filled an empty plastic bottle (which they had painted brown to resemble a volcano) with water, baking soda, washing up liquid and vinegar. This mix caused an eruption, the result of a chemical reaction between the baking soda and vinegar. In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes. As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until the gas bubbles out of the ‘volcano’ (thanks to the soap)! It was a messy, but memorable activity!
