Activity 01

• Simulation Game
• 60 min · Small Groups

Build a Volcano

Pupils construct a model volcano using clay or papier-mâché around a plastic bottle. They can then create a chemical reaction using bicarbonate of soda and vinegar to simulate a volcanic eruption, observing the 'lava' flow.

Explain how convection currents in the mantle cause tectonic plates to move.

Facilitation Tip

Encourage pupils to shape their models differently to represent shield or composite volcanoes before the eruption.

What to look for

Use questioning during the 'Build a Volcano' activity to check pupils' understanding of the eruption process and the parts of a volcano.

Tectonic Plate Jigsaw

Provide pupils with a world map printed on card and cut along the major tectonic plate lines. Pupils work together to reassemble the world map, noticing how the continents fit together and where the plate boundaries lie.

Compare what happens at a convergent boundary with what happens at a divergent boundary.

Facilitation Tip

After assembly, ask pupils to mark famous volcanoes on the map to see the link with plate boundaries.

What to look for

Pupils complete a labelled diagram of a volcano and write a short paragraph comparing the features of a shield and a composite volcano.

Volcano Type Comparison

Give pupils information cards with images and key facts about shield and composite volcanoes. They use a Venn diagram or a comparison table to sort the features, such as shape, eruption type, and lava composition.

Identify the 'Ring of Fire' on a world map and explain its significance.

Facilitation Tip

Provide a word bank of key vocabulary to help pupils articulate the differences accurately.

What to look for

Pupils use a traffic light system (red, amber, green) to indicate their confidence in explaining how a volcano is formed.

Volcano Cross-Section Diagram

Pupils draw and label a cross-section of a volcano. They must accurately place and name the key parts, including the magma chamber, main vent, crater, and layers of ash and lava.

Explain how convection currents in the mantle cause tectonic plates to move.

Facilitation Tip

Offer a pre-drawn template for pupils who need more support with the drawing aspect.

A few notes on teaching this unit

Begin by showing a dramatic video of an eruption to capture pupils' interest. Use simple analogies, like a cracked eggshell for tectonic plates, to explain complex ideas. Hands-on activities like model making will be crucial for consolidating their understanding of a volcano's structure and function.

By the end of this topic, your pupils will be able to explain how volcanoes are formed and compare the different shapes and sizes they come in.

Watch Out for These Misconceptions

• All volcanoes are tall, steep, cone-shaped mountains.

  Volcanoes come in many shapes and sizes. While composite volcanoes are steep cones, shield volcanoes are wide and have gentle slopes, formed by runny lava that travels long distances.

• Lava and magma are the same thing.

  Magma is the name for molten rock when it is still underneath the Earth's surface in the magma chamber. Once it erupts out of the volcano, it is called lava.

• Volcanoes only exist in very hot countries.

  Volcanoes are found where tectonic plates meet, which can be anywhere in the world, including cold places like Iceland and Antarctica. Their location is determined by geology, not climate.
