Science Experiment – Fizzy rocks!

Just recently, the fifth grade class did a experiment to see if rocks will fizz. The answer is yes, as we learned that the acids, vinegar and lemon juice, can dissolve bits of a material called calcium carbonate in limestone. This releases carbon dioxide, a gas that rises to the surface as a stream of bubbles.   Rocks that don’t contain calcium carbonate won’t fizz. We also discussed how acid causes chemical weathering. The students became scientists as they examined each rock, and oh, the excitement when bubbles appeared!
