Volcano Eruption

Volcano Eruption

This is a Basic Earth Science Project In a real volcano eruption, the lava comes out of the volcano. In this project by using baking soda and vinegar we are creating a simple chemical reaction.   The baking soda is a base and the vinegar is an acid. When they react together they form carbonic acid which is very unstable, it immediately breaks apart into water and carbon dioxide, which makes all the fizzing as it escapes the solution. 

In this project, a fake volcano will erupt with a bubbly/fizzy liquid that is produced by this simple chemical reaction.

Alternatives for the Volcano:

  • Buy the plastic volcano from the store and just make the chemical reaction.
  • Make a fake volcano (see Art and craft section for instructions about how to do it).
  • Use an empty plastic bottle and make the experiment before doing the experiment with the unreal volcano; this will allow the students to have a better understanding about what happened inside the volcano.


  1. 3 to 4 tbsp. Baking Soda
  2. ½ cup of vinegar
  3. 5 drops of liquid dishwashing detergent
  4. A container to hold everything
  5. Paper towels ( for the mess)


1. Place some of the baking soda into your container.

2. Pour in some of the vinegar.

3. Watch as the reaction takes place! It quickly fizzes over the container and make sure you’ve got some towels ready to clean up
