Step by Step: Make Your Own Active Volcano at Home!

It's time to experiment! Gather these household items and you and your child will be on your way to building your very own active volcano.


Did you know?

Science (STEM) exploration is part of the Arborland Montessori curriculum as early as 2 years old. By 5 years old, students have the ability to conduct science experiments independently in the classroom.


Things you will need:

  • mason jar

  • foil

  • water

  • baking soda

  • dish soap

  • red food coloring

  • vinegar


Follow these simple steps:

  1. Wrap the foil around the mason jar in the shape of a mountain, giving the “lava” a slope to run down.

  2. Inside the mason jar, add water, 4 tablespoons of baking soda, a small squirt of dish soap, and a few drops of food coloring.

  3. Add a few tablespoons of vinegar to active your volcano.

  4. Watch the as the volcano comes to life!


Why does this happen? A chemical reaction between vinegar and baking soda occurs. When these two are mixed, it creates a gas called carbon dioxide. Carbon dioxide escapes your volcano as bubbles!
