STEAMInsights: EXPLORING CHEMISTRY FOR KIDS

As parents, we know that kids love activities that fizz, bubble, and explode (safely, of course!). One of the most exciting and easy science experiments for kids is creating a model volcano that erupts using baking soda and vinegar. This classic STEAM activity is perfect for introducing children to the fascinating world of chemistry while also encouraging creativity and hands-on learning.
About the Chemistry for Kids

At the heart of the baking soda and vinegar volcano is a simple yet exciting chemical reaction. Baking soda (sodium bicarbonate) is a base, and vinegar (acetic acid) is an acid. When they are combined, they react to form carbon dioxide gas, water, and sodium acetate. The carbon dioxide gas creates bubbles and foam, which rush out of the volcano’s opening, mimicking a real volcanic eruption.
This reaction is not just fun—it’s a great way for children to:
Learn about acids and bases
Observe gas formation
Understand cause-and-effect relationships in science
See how chemical reactions can be applied to real-world phenomena (like volcanic eruptions)
Hands-On Activity: Build and Erupt Your Own Model Volcano
Materials Needed:
Baking soda (about 2–3 tablespoons)
Vinegar (about 1 cup)
Dish soap (optional, for extra foamy lava)
Red and yellow food coloring (optional, for a lava look)
Small plastic cup or bottle (for the eruption chamber)
Modeling clay, playdough, or paper mache (to build the volcano)
A tray or large dish to contain the mess
Step-by-Step Instructions
Step 1: Build Your Volcano
Place your plastic cup or bottle in the center of the tray. Using clay, playdough, or paper mache, shape the volcano around the cup, leaving the top open. This is your volcano’s crater. Encourage kids to be creative—add rocks, trees, and other details to make it realistic.
Step 2: Prepare the “Lava”
In the cup, add:
2–3 tablespoons of baking soda
A few drops of dish soap (for foamier lava)
A few drops of red and yellow food coloring (for realistic lava color)
Step 3: Erupt the Volcano
When you’re ready for the eruption, pour vinegar into the cup and watch the foamy, bubbly lava flow out!
Step 4: Experiment and Explore
Encourage your child to try variations:
Use warm vinegar to see if the reaction speeds up.
Add more or less baking soda to see how it affects the eruption.
Try adding glitter for “sparkling lava.”
