Build a Baking Soda Volcano

The baking soda volcano is one of the most exciting STEM activities for children because it combines creativity, chemistry, and hands-on experimentation. Children design and build a volcano model, then create a chemical reaction using baking soda and vinegar. The bubbling eruption captures attention immediately while teaching important scientific concepts. This activity encourages observation, prediction, and experimentation, helping children understand how gases form during chemical reactions in a safe and memorable way.
