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 hidden under the ocean?
In the United States, you can find active volcanoes in places like Hawaii, Alaska, California, Oregon, and Washington. The biggest active volcano in the world is Mauna Loa in Hawaii, which erupted in November and December of 2022.
Volcanoes are formed by movements in the Earth’s crust. When hot, liquid rock called magma pushes its way to the Earth’s surface, it creates a volcano. Magma is found deep underground, and when it reaches the surface, it turns into lava, which flows out during an eruption.
An eruption happens when gas bubbles inside the magma expand, increasing the pressure inside the volcano. This pressure looks for weak spots in the Earth’s crust to escape. When it finds one, the magma bursts out as lava. Isn’t that fascinating?
As volcanoes erupt over and over, the cooled rock makes them grow bigger and bigger.
Did you know that most volcanoes are located in an area called the Ring of Fire in the Pacific Ocean? This is also where many earthquakes happen because the Earth’s surface is always moving there.
Volcanoes can be in three stages: extinct, dormant, and 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 in Hawaii.
Now that we know more about volcanoes, let’s make our own model volcano! Remember, this is just for fun, and it can get a little messy, so it’s best to do it outside or in a place that can be cleaned easily.
Wasn’t that exciting? Science can be so much fun!
After your experiment, think about how your model was like a real volcano and how it was different. Talk about your observations with your family or friends. Next time, try doing this experiment with a group for even more fun!

Volcano Scavenger Hunt: Go on a scavenger hunt in your backyard or a nearby park to find materials that resemble parts of a volcano. Look for rocks, dirt, and sand. Can you find something that looks like cooled lava? Take pictures or draw what you find and share it with your class.
Volcano Story Time: Imagine you are a volcano! Write a short story or draw a comic strip about what it feels like to be a volcano. What do you see, hear, and feel when you erupt? Share your story or comic with your classmates and discuss how it relates to what you learned about real volcanoes.
Volcano Observation Journal: Keep a journal for a week where you note down any volcano-related news or facts you come across. This could be from books, TV, or the internet. Write a sentence or draw a picture about what you learned each day. At the end of the week, share your favorite fact with your class.
Sure! Here’s a sanitized version of the transcript:

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 flows out of a volcano during an eruption.
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. Once 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. The more this process happens, the larger the volcano becomes.
Here’s another interesting fact about volcanoes: 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. 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, you need to gather your materials. Have an adult help you. Here is 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 jazz it up a bit. Oh yeah, 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 is 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 pizzazz if you want to. Stir the ingredients together with your stirring tool.
For the grand finale, slowly pour the white vinegar into your volcanic concoction 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!
