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 🧪 🪨
