Magma is molten or partly molten rock below the surface. Material erupted onto the surface is called lava. A simple cross-section can show a storage region, a route upward, and a surface opening. Real volcano plumbing is more complex than one large empty tank and a straight pipe. Safety: No heat, chemicals, gases, pressure, or eruption experiment. This is a classroom diagram, not a forecast. Stop: Stop after explaining the paper route. Do not make a reacting volcano, use heat, seal bottles, or visit volcanic ground.

Materials: Paper; Pencil; Red or orange pencil if available 1. Draw a wide triangle on a horizontal ground line. Extend a rectangle of underground space below it. Label the view Side slice through an illustrative volcano; not to scale. Leave room for words outside the mountain. 2. Draw an oval storage region below ground, a narrow path from it to the top, and a bowl-shaped opening at the summit. Label them Magma storage region (often called chamber), Vent or conduit, and Crater. Add short leader lines so each label reaches its feature. 3. Colour or mark the material below ground Magma. Draw a small tongue of material leaving the summit down one side and label it Lava. Add arrows along one possible upward route. 4. Write a three-part route using the exact feature labels. Then complete: The name changes at __; the material is still __. Add a limit sentence: This drawing does not show all cracks, side vents, crystals, or gases. Done: A labelled cross-section, five material/feature labels, route arrows, and a below/above-ground explanation are complete. Proof: Keep the cross-section and route sentence. Note help drawing, reading labels, or identifying the surface boundary. Stop: Stop after explaining the paper route. Do not make a reacting volcano, use heat, seal bottles, or visit volcanic ground.
