Free Earth Science Adventures

Twelve underground worlds, six stops in each. A Grumblie has emptied every Dig in the Realm and your class has to put the place right to get them back. No student logins, no accounts, nothing to install, and no cost — permanently.

How teachers actually use these

  • Assign one stop, not the whole unit. Every stop has its own address — /pages/lava-safari#stop-4 — which pastes straight into Google Classroom.
  • Ten to fifteen minutes each. One stop fits a warm-up, a station, or the last part of a lesson.
  • Progress is remembered on the device, so a class can do one stop a week and pick up where it left off.
  • Six stops opens the finale. That's the payoff, and it's the same mechanic as the physical kit.

What the kits add

The adventures are the half you can do today. The kits are the half a screen cannot do: six real rocks, minerals and fossils, each sealed in a Dig with the specimen name hidden under a scratch-off, six 3D-printed Gemlings in a blind bag, and the printed Realm map. Finish a stop online and that location's Dig is yours to open for real.

Every kit sold donates one to a school. No minimum, no ceiling, no selling, no order forms — your PTA sends one email and the donated kits arrive in one batch.
