Dry Ice: A Frozen Mixture Of Carbon Gas

Background research Dry ice is a frozen mixture of Carbon dioxide, and like many other mixtures that give off Carbon dioxide dry ice is able to fill up a balloon. Using other substances that give off Carbon dioxide along with dry ice, which substances would be able to give off enough Carbon dioxide to inflate a balloon. The scientist will of course be controlling many variables. The scientists independent variable will be the substances they will be using, which is dry ice, yeast, and baking soda with acid. The scientist will also have substances that will remain constant, i.e., the balloons, the size of the bottles used and the amount of substance the scientist uses.

While there have been many different variations
