Volcanic Eruptions!

After many days of preparation, building and painting, Year 3 finally got to erupt their volcanoes.  Using a mixture of bicarbonate of soda, vinegar, washing up liquid and food colouring the children created an explosive chemical reaction!  The children made lots of observations and noticed that the shape of the volcano (they were all based in real volcanoes) changed how the lava flowed out.  There was a lot of fun and mess!
