Testing the Composition of Rocks – 3 Blue

Today children tested different rocks and placed them in vinegar to observe the fizziness if any. They were pleased to see that some rocks did fizz in the vinegar whereas others didn’t. They discovered that it is the calcium carbonate in rocks that promote the release of carbon dioxide and the bubbles in the surface are as a result of the gas being released. Children thoroughly enjoyed the experiment today and later celebrated their learning of rocks through a poster. Watch the video below to catch a sneak peak of the experiment 🧪 🪨

    We tested chalk,basalt,slat,and all the others.and some of the rock fizzed and changed colour. And it’s fizzing like lemonade. Gabbro was fizzing when it was in vinegar and it was starting to fizz and bubbles and he top. Chalk fizzed the most like soap and bubbles.and it was more than limestone the fizzed had lemon and other things. The scientific reason was because the vinegar was in the pot.
    It contains carbon gas and in the vinegar I enjoyed it a lot the most favourite one of myself. Was, the limestone that was fizzing a little bit.

    I enjoyed it a lot. And the one that fizzed a lot was chalk and the one that didn’t fizz the most was slate and basalt. And we also putted vinegar in the pots.

    Chalk fizzed the most because it was spreading in the vinegar.
    Basalt and slate did not fizz because there was no bubble reaction.
