We need to find the independent variable, and the dependent variable, in an experiment we did. The experiment? Is the law of conservation of mass valid. We took alka-seltzer, put it into a graduated cylinder, taped a balloon over it, and weighed it x4. What are they? :L |

| We need to find the variables in just the experiment itself. |

| The independent variable is the presence of Alka Seltzer, the independent variable is the weight of the balloon. |
