Have you ever wondered what a volcano is? There are about 1,500 active volcanoes around the world, and every day, 15 to 20 of them erupt! Today, we’re going to learn all about volcanoes and even do a fun experiment. Are you ready? Let’s dive in!
A volcano is a special kind of mountain. It’s made from cooled lava, ash, and other materials from past eruptions. Did you know that out of all the active volcanoes on Earth, about 80 are under the ocean?
In the United States, you can find active volcanoes in Hawaii, Alaska, California, Oregon, and Washington. The largest active volcano in the world is Mauna Loa in Hawaii, which erupted in November and December of 2022.
Volcanoes are created by movements in the Earth’s crust. They form when magma, which is super hot liquid rock beneath the Earth’s surface, rises up. When magma reaches the surface, it becomes lava, which flows out during an eruption.
An eruption happens when gas bubbles in the magma expand, increasing pressure inside the volcano. This pressure finds weak spots in the Earth’s crust and bursts through, releasing lava. Isn’t that fascinating?
As volcanoes erupt over and over, the cooled rock makes them grow bigger. The Pacific Ocean’s “Ring of Fire” is where most volcanoes and earthquakes happen because there’s a lot of movement in the Earth’s crust there.
Volcanoes can be in one of three stages: extinct, dormant, or active. An extinct volcano hasn’t erupted for thousands of years and probably never will again. A dormant volcano hasn’t erupted in a long time but might in the future. An active volcano has erupted recently and could erupt again soon, like Mauna Loa.
Now that we know more about volcanoes, let’s create our own model volcano! Make sure you have an area that can get a little messy, or go outside if the weather is nice.
Wasn’t that fun? Science can be really exciting!
After your experiment, think about how your model volcano was like a real one. How was it different? Share your thoughts with family or friends. Next time, try doing this experiment with a group!

Volcano Observation Walk: Take a walk around your neighborhood or a nearby park with an adult. Look for natural formations like hills or mounds. Imagine if they were volcanoes! Discuss with your adult companion how they might look if they erupted. What would happen to the area around them? Draw a picture of what you imagine.
Volcano Story Time: Create a short story about a volcano. Give your volcano a name and describe what it looks like. Is it active, dormant, or extinct? What happens when it erupts? Share your story with your class or family. You can even act it out with friends, using your model volcano as a prop!
Volcano Eruption Diary: Keep a diary for a week where you pretend to be a volcano. Write a short entry each day about what you “see” and “feel” as a volcano. Are you rumbling with activity, or are you calm and quiet? What do you think about the world around you? This will help you understand the life cycle of a volcano.

What is a volcano? Did you know that there are around 1,500 active volcanoes in the world today? Every day, about 15 to 20 volcanoes erupt. Today, we are going to learn more about volcanoes and do a fun experiment together. Ready to get started? Let’s go!
First, let’s talk about what a volcano actually is. A volcano is a mountain made of cooled lava, ash, or other material from a previous volcanic eruption. Here’s an interesting fact about volcanoes: of the over 1,500 active volcanoes on Earth, about 80 of them are actually located under the ocean.
In the United States, active volcanoes can be found in Hawaii, Alaska, California, Oregon, and Washington. The world’s largest active volcano is Mauna Loa in Hawaii, which most recently erupted in November and December of 2022.
Volcanoes are caused by movements of the Earth’s crust. They are formed when magma makes its way to the surface of the Earth. So, what is magma? Magma is extremely hot liquid and semi-liquid rock located underneath the Earth’s surface. When this molten rock reaches the surface, it becomes lava, which is what flows out of a volcano when it erupts.
An eruption happens when gas bubbles inside the magma expand and increase the pressure inside the volcano. Once that pressure builds, it wants to escape, pressing on the Earth’s crust and finding weak spots where it can break through. When these weak spots are found, the magma bursts through and exits the volcano in the form of lava. Pretty cool, right?
As volcanoes erupt repeatedly, the rock cools, making the volcano larger and larger. The more this process happens, the bigger the volcano becomes. Here’s another interesting fact: the Ring of Fire in the Pacific Ocean is where most volcanoes are located and where most earthquakes originate. That’s because there is a lot of movement happening on the surface of the Earth.
There are three volcanic stages: extinct, dormant, and active. Can you guess which of these three is the extinct volcano? Yep, it is the one on the left. An extinct volcano has not erupted for thousands of years and will probably never erupt again. A dormant volcano has not erupted in a long time but could erupt in the future, while an active volcano is one that has recently erupted and may erupt again soon, like Mauna Loa in Hawaii.
Now that we know more about volcanoes, let’s make one! Well, not literally, of course, but we can create our own model volcano and have a lot of fun while we do it. First, make sure you set things up in an area that can get a little messy. If the weather is nice, you can even go outside.
Next, gather your materials with the help of an adult. Here’s what you will need for this experiment: a plastic cup or empty plastic water bottle, dirt, sand, or rocks, water, baking soda, white vinegar, dish soap, something to stir with (like a spoon or a stick), and some washable paint if you want to add some color. Oh, and don’t forget your measuring spoons; you will need a teaspoon and a tablespoon for this activity.
We will wait for you to get everything ready.
Okay, now for the fun part! First, fill the cup or water bottle about two-thirds full of water. Then, make a mound of sand, dirt, or rocks around the cup; this will be the outside of the volcano. Next, add four to six tablespoons of baking soda to the water, then add one teaspoon of dish soap and a splash of paint for some extra fun. Stir the ingredients together with your stirring tool.
For the grand finale, slowly pour the white vinegar into your volcanic mixture and watch it erupt! Nice job, friends! Science can be pretty fun, huh?
Now that you have finished this experiment, let’s talk about your observations. How was this model like a real volcano? How is it different? Record and discuss your results with your family or friends. Next time, grab a group of people and do this fun experiment together!
