After spending a few weeks learning about solids, liquids and gases, we were ready to make our own gas. Students combined a liquid (vinegar) and a a powder (baking soda) to make a gas! We had evidence that a gas spreads out as far as it can and takes up all the space possible when the baking soda hit the vinegar and our balloons blew right up! The little scientists loved it! They were a tiny bit surprised at how quickly the balloons inflated. One balloon even popped because the gas pushed a little too hard on the inside of the balloon. It was a successful learning experience!
