Build a small volcano model to demonstrate how volcanic eruptions occur. The project uses simple chemical reactions to mimic lava flow.
If baking soda and vinegar are mixed, then a foamy eruption will simulate a volcanic eruption.

Shape the clay around the plastic bottle to form a volcano structure.
Add baking soda into the bottle.
Mix vinegar and food coloring in a separate cup.
Slowly pour the vinegar mixture into the bottle.
Observe the chemical reaction that simulates an eruption.
Repeat the experiment with different amounts of baking soda.
Record observations of each eruption.
Clean the area and dispose of materials properly.
The reaction between baking soda and vinegar will create a foamy eruption, similar to a volcanic eruption.
Amount of baking soda
Height of eruption
Type of vinegar, Bottle size, Clay shape
Wear safety goggles and gloves when handling vinegar and baking soda.
Explain the chemical reaction in simple terms.
Use a video to capture the eruption for your display.
Discuss the similarities of the model to real volcanoes.
They react to form carbon dioxide gas, causing fizzing.
Other acids can be used, but vinegar is safe and effective.
It simulates the eruption but is different from actual volcanic explosions.
