Exploding Volcanoes

  1. 1. ChemicalReactions.Today we made volcanoes.First we were split into four groups of four, (a mix of Year 1-3’s). Then wewent down to the sand pit where we built our volcanoes and little towns,villages and forests.When we were finished building we put a little plastic cup inside our volcanoes.This would hold the baking soda and red food colouring.We poured the vinegar into our volcanoes. There was a chemical reactionbetween the baking soda and the vinegar. They frothed together and shotout of our volcanoes. The red food colouring made the froth look like red hotlava. The lava ran down one side of our volcanoes , but our towns ,villages andforests luckily………..SURVIVED!!!
