Primary six pupils were delighted to welcome parents and grandparents into our classroom on Friday morning.  Pupils have been learning about the scientific understanding of the Earth’s evolution.  As part of this topic we looked at natural disasters including volcanic eruptions.  Pupils carried out a practical investigation to find out which elements would react together to re-create a volcanic eruption.  We mixed bicarbonate of soda with vinegar (and a little red chalk to represent the colour of lava).
