Quick check

If the learner sees a picture of a volcano erupting, can they explain that it's an opening in the ground where very hot melted rock comes out?

What mastery looks like

What a learner can do once this topic is secure.
  • Describe a volcano as a place where hot material comes out of the Earth
  • Explain that lava is rock so hot it has melted
  • Point to a volcano in a picture and describe what is happening

The approach

For 5–7 year-olds, establish a clear mental picture of a volcano: an opening in Earth's surface where hot melted rock (lava) comes out. The single most important idea is that lava is ROCK so hot it has melted and glows because of its heat — not fire, not a burning flame, and not some separate special liquid different from rock. Keep the work definitional (recognise, name, describe); defer magma chambers, vents, plate boundaries and eruption mechanism to later (7–9) topics. Build from vivid real imagery and a simple three-part labelled cross-section, and give children sentence frames to narrate what they see.

Common misconceptions

  • 'The glowing lava is fire' — it is rock so hot it has melted and glows; there is no burning flame in the flow
  • 'A volcano is a mountain that breathes fire / a fire-breathing monster' — it is an opening in Earth's surface where melted rock comes out
  • 'All volcanoes are tall pointed mountains' — the defining feature is the opening, not the cone shape
  • 'Lava comes straight from the centre of the Earth' — at this age keep it to 'from hot melted rock underground'; deep structure comes later
  • 'Volcanoes only existed long ago / are not real now' — many volcanoes are active today

Useful representations

  • Labelled volcano cross-section (mountain, opening/vent, lava flow, ash cloud)
  • Before-and-cooled pair: glowing orange lava → solid black rock (lava is rock)
  • Real photographs/footage of an erupting volcano
  • A simple 'opening in the ground' schematic that de-emphasises the mountain (not all volcanoes are tall cones)

Teaching practices

  • Anchor on vivid real imagery/footage first (a glowing lava flow, an ash plume) so the concept is concrete before any diagram
  • Lead with the core correction 'lava is melted ROCK, not fire' — say it, show glowing lava cooling into solid black rock
  • Use a simple labelled cross-section with only three parts a child can point to: mountain, opening (top), lava coming out
  • Bridge from Y1 everyday materials ('rock is a material') so 'melted rock' is believable rather than magical
  • Give sentence frames to narrate a picture ('hot melted rock — lava — is coming out of the opening') to meet the 'point and describe' evidence
  • Defer magma/chamber/vent vocabulary and eruption mechanism to the 7–9 topics; keep this purely definitional

Activities to try

  1. 1

    Tap-and-name the volcano picture

    Why it works: A volcano is an opening where hot melted rock comes out; lava is rock that has melted and glows because it is so hot, and it cools back into solid rock.

    1. Look at a large, friendly cross-section of an erupting volcano (mountain, opening at the top, lava flowing down, ash cloud).
    2. Tap each part to hear/read a short naming phrase: 'the mountain', 'the opening at the top', 'the lava coming out', 'the ash cloud (tiny bits of rock, not ash from burning)'.
    3. Open a lift-the-flap sitting on the lava: front asks 'What is lava?', the flap reveals 'Rock so hot it has MELTED — it glows because it is hot, it is not fire.'
    4. Zoom in on a close-up where a blob of glowing orange lava cools and hardens into solid black rock.
    5. Narrate the whole picture aloud using a sentence frame: 'The hot melted rock — lava — is coming out of the opening.'
  2. 2

    Press to erupt

    Why it works: Hot melted rock comes OUT of the opening of a volcano, and as it flows away and cools it hardens into solid rock.

    1. Tap the volcano to make it erupt: watch lava well up at the opening and flow down the sides.
    2. Watch the lava cool from bright orange at the top to solid black rock at the cooled edges.
    3. Read the caption that names the flowing stuff 'lava'.
    4. Say in your own words where the lava is coming out and what happens as it cools.
  3. 3

    Melt-and-cool prediction (hands-on check)

    Why it works: Glowing and hot does not mean burning: a melted solid flows while hot and hardens again when cooled, just as lava (melted rock) cools into solid rock. The wax/chocolate shows melting and re-solidifying; the glow is a feature of lava's extreme heat, not of the stand-in.

    1. Look at a solid piece of wax or chocolate.
    2. Before anything happens, PREDICT: if we heat it until it flows like lava and then let it cool, will it (a) burn up into ash, (b) turn into fire, or (c) become solid again — and say WHY. (Then we test it to see what really happens.)
    3. An adult gently warms it (for example in a bowl over warm water, away from any flame) until it flows, then let it cool, and check what actually happens.
    4. Connect it back: like lava, a hot melted solid can flow while it is hot and then harden back into a solid when it cools. Lava is far hotter, so lava also glows; the wax or chocolate is not hot enough to glow.
    5. Answer the probes: 'If the glowing lava cools right down, what does it turn into?', 'Where does the melted rock come from — the top of the mountain, or from hot melted rock underground?', and 'Is the volcano hot because something is burning, or for a different reason?'
