Today in science class our teacher, Mrs Kuruvilla decided that we would do a practical for period 5. During the past weeks, we have been learning about volcanoes as well as earthquakes. We did an experiment based around the eruptions of volcanoes.The reaction was made using baking soda and vinegar. We first measured 5ml of vinegar into a measuring cylinder. Then once accurately measured and checked by our teacher, we then poured the liquid into a test tube. After this, we put a drop of pink food colouring in it to give it a bit of colour. It actually looked quite pretty. But yeah, then we put a little bit of baking soda in the test tube along with the food colouring and vinegar. It didn't erupt as much as we would've liked it to, but we're glad that it still worked.
This showed us a little real life demonstration of how volcanoes erupt. Just without the heat. It was a bit satisfying to watch the chemicals come together and slowly rise to the top, which eventually ended up falling out of the test tube. But, we learned that volcanoes can erupt slowly, but they are still very dangerous to be around. Especially when they are still active.
