Explaining Volcanoes 13.12.13

This week year 6 have researched, planned and written explanation texts to give information about how and why volcanoes erupt.  On Friday we followed instructions to build a 'working model' of a volcano.  After building our volcanoes, we used a mixture of vinegar, washing up liquid and red food colouring added to bicarbonate of soda to create an erupting volcano.
