Rocklings: Trapped in the Crystal Caverns - Rocks and Minerals Adventure Pack

Trapped in the Crystal Caverns

Rocklings • Rocks and Minerals Gemlings Adventure Pack

A deep underground system beneath the Grand Canyon has gone unstable.

Sensors are detecting fractures inside the Crystal Cavern Core, a hidden subterranean network beneath the canyon where the Rocklings help maintain balance between rocks, minerals, crystals, and Earth’s surface processes. Ari Raider has traced the disturbance to a powerful specimen hidden inside a sealed Mystery Mine. The Professor accessed these caverns through deep fault lines, disrupting crystal grids and triggering collapsing stone chambers.

In Trapped in the Crystal Caverns, students journey beneath the Grand Canyon alongside the Rocklings on a high stakes escape room style mission. From identifying rock types and understanding the rock cycle to testing mineral properties, fossil layers, erosion, and crystal growth, explorers must use real geology knowledge to stabilize each chamber, locate the hidden Mystery Mine, and recover the missing specimen.

This adventure transforms rocks and minerals into a story driven mission focused on Earth science, observation, and problem solving.
