Year 4 Pupils Make Volcanoes
Whilst on a school visit to teach about dinosaurs and fossils one of our teaching team was given the chance to view an excellent display of volcanoes made by Year 4 pupils as they studied rocks and the formation of the Earth. There was some amazing artwork on display and under the teacher’s tutelage, some children had even made models. Some of the models spouted lava flows made from coloured tissue paper, other volcano models had been prepared for use later on in the day, where with the addition of vinegar and bicarbonate of soda, they were going to “erupt”. Carbon dioxide produced in the plastic drinks bottle that helps to form the cone shape will force out the liquid lava as the gas pressure builds. It is a good idea to put plenty of newspaper down to keep mess to a minimum and we like to add a few drops of washing up liquid to help the lava bubble. Food colouring can be used to create, red, orange and even blue lava – whatever colour takes your fancy!

We discussed the extinction of the dinosaurs as part of our dinosaur workshop and we looked at other theories about the Cretaceous mass extinction, including volcanic activity leading to dramatic climate change.

It certainly was a most enjoyable day, one that delighted our geologist colleagues when the saw the pictures of the children’s work.
