General Chemistry Science Fair Project

Baking Soda Volcano

Baking Soda Volcano | Science Fair Projects | STEM Projects
Get ready to explore the world of chemistry! Mix baking soda and vinegar together and watch the volcano eruption! This is an acid-base reaction, where the acidic vinegar neutralizes the basic baking soda. Carbon dioxide is given off in the process, causing the baking soda volcano to erupt.


The hypothesis is that mixing baking soda and vinegar will create a fizzing, bubbling reaction.

Method & Materials

You will need to place some baking soda in a container and then pour in some vinegar.
You will need baking soda, vinegar, a container, and paper towels.


The experiment showed that when baking soda and vinegar are mixed together, a fizzing, bubbling reaction is created. This is an acid-base reaction, where the acetic acid neutralizes the basic sodium bicarbonate. Carbon dioxide gas is given off in the process, creating the bubbling reaction.

Why do this project?

This fun and classic science project is a great way to explore the chemical reaction that takes place between acids and bases. You'll also get to see how the solids and liquids (the starting materials) transform into carbon dioxide gas during the experiment, which provides an engaging and thorough chemistry lesson.

Also Consider

Experiment variations to consider include adding food coloring to the vinegar or using different types of vinegar.
