Volcano experiment

Some of the children have been involved in building a volcano using the sand therefore we decided to experiment in making a scientific exploding Volcano.

We made our Volcanic mountain by compacting sand around a drinks bottle.

 Red food colouring was added to Bicarbonate of soda and placed in the drinks bottle.

The children then took it in turns to pour vinegar into the bottle and watch what happens.....

 

 

 

The children discussed how hot 'Lava' is and one child said 'This is what killed the dinosaurs.'

The mixture foamed over the top of the bottle and we watched as it bubbled over the sand.
