Volcanic eruptions in Year 5!

As part of Year 5's Fierce Earth topic we spent the morning finding out about volcanoes. We created our own salt dough models of volcanoes, before erupting them after break. We put bicarbonate of soda into our volcanoes before pouring in vinegar to cause a chemical reaction. The reaction caused our volcanoes to 'erupt' (we added in red food colouring to make the liquid look like lava). As a grand finale we 'erupted' the big paper mache volcano, which some of us had made as a special project. To make it feel like a real volcanic eruption we even played sound effects of volcanic eruptions in the background!
