Baking soda has a similar volume and mass, in that 10mL of baking soda weighs about 10 grams, and so on. This meant I could weigh the baking soda on a scale rather than have to measure it by volume. I then made five volcanoes with each amount of baking soda, for a total of 15 volcanoes. The explosion happens very quickly — too fast to mark its height accurately on a wall or yardstick.

But once the eruption happens, the foam and water fall outside the bottle. By weighing the bottles before and after the reaction, and adding in the mass of the baking soda and water solution, I can calculate how much mass got ejected from each eruption.

I could then compare the mass lost to show if more baking soda produced a larger explosion. When I used only 10 grams of baking soda, the bottles lost 17 grams of mass on average. The eruptions were so small that most never made it out of the bottle.

When I used 50 grams of baking soda, the bottles lost grams of mass on average. And when I used grams of baking soda, the bottles lost almost grams of mass. Because I added different amounts of baking soda and water to the bottles, there might not be as big of a difference here as I think. The extra mass from the gram bottles, for instance, could just be because the reaction started out heavier. To rule that out, I converted my numbers to the percent of mass lost.

The gram bottles lost only about three percent of their mass. The gram bottles lost 25 percent of their mass, and the gram bottles lost more than half of their mass. To confirm that these results are different, I need to run statistics. These are tests that will help me interpret my results.
