Visualize: What would a real volcano eruption look like? What would you see? What would you hear? What would you feel? What would you smell?

Building a Volcano

You need to follow all of the instructions “precisely” in order for your volcano to work correctly.

1. Get you materials. You will need:
• Large Pieces of Paper
• Modeling Clay or Salt Dough
• Small Empty plastic soda bottle
• Baking Pan
• Red Food Coloring
• Liquid Detergent
• Baking Soda
• Funnel
• Vinegar

2. Place the Soda Bottle in the Baking Pan.
3. Mold the Clay or Dough into a “Mountain” around the bottle.
4. DO NOT cover the bottle opening or allow any material to get inside the bottle.
5. Fill the bottle ALMOST to the top with warm water.
6. Ask Ms. Webb to add a few drops of red food coloring.
7. Place your volcano back on the Baking Pan
8. Use the Funnel to Add Baking Soda to the Bottle.


9. Use the funnel to slowly pour the vinegar into the bottle.

Draw a picture of the “action” that took place:

What did the read mixture that foamed out of the volcano represent? _____________________

How hot do you think lava is? ________________________

So What Really Happens When a Volcano Erupts?

The molten metal that makes up the earth’s core is called _____________. Extreme heat can cause bubble of carbon dioxide gas in the magma to expand. This expanding gas pushes the magma to the _________ or opening of the volcano on the earth’s surface. A volcanic ______________ eruption occurs when the magma overflows. The overflowing magma is also called ___________.

What 2 things did you mix together to create the carbon dioxide gas? ____________ and ________________

These gas bubbles build up inside the bottle, forcing the liquid out of the bottle.

Think About It:
How does a volcano eruption impact the environment?
How does it pact humans?
