Volcano Inside

Heat and expanding trapped gas build pressure in a magma chamber; that pressure forces magma up a vent, and more stored pressure produces a bigger eruption.

What your child will figure out

  • Locate the magma chamber in Earth's crust and connect it to the crater through the main vent.
  • Manipulate heat and trapped gas to make chamber pressure and magma height change together.
  • Predict and compare gentle and large eruptions from the amount of stored pressure.
  • Transfer the pressure model to a volcano with a broader, lower-resistance vent.

The levels

  1. Inside the mountain

    Find the crustal chamber, main vent, and rock layers.

  2. Wake it gently

    Build moderate pressure, predict magma height, and make a gentle eruption.

  3. Make the big one

    Store more pressure than before and produce a visibly larger eruption.

  4. Wide-vent transfer

    Tune a gentle eruption in a volcano whose broad vent releases pressure more easily.

Ready when they are.
