Our Volcano in Class

Yesterday we did a volcano experiment in our class. First our teacher made a cone shape of the play dough. She then added enough baking soda in small cup which was placed in the centre of the play dough.

We all sat quietly and watched her.

Then she added some vinegar to the baking soda.

Eruka, there was this oozing out of bubbles which showed how the volcanoes erupt.

    That was a good experiment to demonstrate how volcanoes erupt. Have you watched any videos of volcanoes erupting?
