ClassX Video Lessons Youtube Channel Next Generation Science Lighthouse Lab – Modelling a Volcanic Eruption
Welcome to The Lighthouse Lab! Today, we’re going to learn how to make a model of a volcano. Volcanoes are amazing natural features that can be different shapes and sizes. They are openings in the Earth’s crust where hot, melted rock called magma erupts and flows out. Some famous volcanoes are Heimaey in Iceland, Mount Vesuvius in Italy, Mount Merapi in Indonesia, and the many volcanoes in Hawaii, USA.
To create our volcano model, we’ll mix some safe chemicals. Even though they are mostly harmless, they can irritate small cuts, so we need to be careful. I’ll wear rubber gloves and goggles for safety. I’ll also use food coloring, so a lab coat will help keep my clothes clean.
Let’s start by making some lava bombs! In a small container, I’ll mix two scoops of bicarbonate soda with one scoop of citric acid. Then, I’ll add a few drops of red food dye to make it look like real lava. I’ll mix it with a popsicle stick until it becomes pink and crumbly. Now, I’ll press the mixture into a rock mold. It looks great! I’ll make another one using yellow food dye for a different look. We’ll let them dry for a few minutes.
Now for the exciting part: the eruption! I’ll place the dried lava rocks inside the volcano craters, which are called calderas. Then, I’ll add 15 mL of water to a beaker and mix in eight drops of dish soap. Watch closely! The red lava rock reacts with the water and soap, just like a real volcanic eruption. Inside a volcano, the hot, melted rock is called magma. When it flows out, it’s called lava. As the lava cools, it turns into solid rock.
You can also try making a volcanic eruption at home using baking soda and vinegar. Just remember to have an adult help you. Add four scoops of baking soda to a container, then mix red food dye with vinegar and pour it in. Watch the fizzing eruption! It’s so cool!
Have fun trying this experiment with your friends and family, but always remember to wear gloves and goggles for safety. See you next time for more exciting science adventures!
Volcano Observation Walk: Take a walk in your neighborhood or a nearby park with an adult. Look for natural features like hills or mounds that remind you of volcanoes. Imagine what it would be like if they were real volcanoes. Draw a picture of what you see and label it with parts of a volcano, like the crater and lava flow.
Volcano Art Project: Create a volcano collage using different materials. Use colored paper, cotton balls, and glitter to represent the magma, lava, and ash. Think about how the colors and textures can show the different parts of a volcanic eruption. Share your artwork with your class and explain what each part represents.
Question Time: Discuss with your family or friends: Why do you think volcanoes are important to the Earth? How do they help shape the land? Write down your thoughts and share them with your class. You might discover new ideas about how volcanoes affect the world around us!

Welcome back to The Lighthouse Lab! Today, we’re going to learn how to make a model of a volcano. Volcanoes can be different shapes and sizes, but they are all openings in the Earth’s crust through which molten rock erupts and flows. Some famous active volcanoes include Heimaey in Iceland, Mount Vesuvius in Italy, Mount Merapi in Indonesia, and the many active volcanoes in the American state of Hawaii.
To model a volcanic eruption, I’m going to mix some chemicals. They are mostly harmless, but can cause irritation to small cuts, so it’s important to take precautions. I’ll be wearing rubber gloves and goggles for safety, and I’ll also be using food coloring, so this lab coat will help protect my clothes.
Let’s get started! First off, I’m going to make some lava bombs. In a small beaker, I’ll add two scoops of bicarbonate soda and one scoop of citric acid. Now, I’ll add a few drops of red food dye to give the lava a reddish appearance. Let’s mix it up with a popsicle stick until it’s pink and crumbly. Perfect! Now I’ll pour it into my rock mold and press the mixture firmly together.
Looking good! Let’s make one more and use yellow food dye to change things up a bit. I’ll leave the lava rocks for a few minutes to let them dry. Once they’re ready, I’ll take out each rock and place them inside the volcano craters. Volcanoes shaped like this are called calderas.
Now for the fun part: the eruption! I’ll add 15 mL of water to this beaker and then add eight drops of dish soap. Are you ready? Cool! The red lava rock is reacting with the water and dish soap. Inside a volcano, molten rock is called magma. When it flows onto the surface of the Earth, it’s called lava, and when the lava cools, it solidifies and forms rock.
Let’s see that again! You can also model a volcanic eruption using simple household items like baking soda and vinegar. If you do, make sure there’s an adult around to help you. I’ll add four scoops of bicarbonate soda to the measuring cylinder, then I’ll add a few drops of red food dye to the vinegar, and now I’ll pour it in. Wow, that was cool!
Try this with your friends and family, but remember to have an adult around and don’t forget to wear gloves and goggles. See you next time!
