Essential Testing Tools

Every identification method used by professional geologists, adapted for interactive mobile learning

◆

Interactive Scratch Testing

Drag a virtual glass plate across mineral specimens to determine hardness ratings. Feel the resistance as you test against the Mohs scale, learning which minerals scratch glass and which are scratched by it.

■

Streak Plate Analysis

Observe authentic streak colors as you test minerals against porcelain plates. Discover why pyrite leaves a greenish-black mark while galena produces gray streaks, revealing hidden chemical properties.

▲

Weight Density Challenges

Compare the heft of identical-sized specimens to understand density variations. Learn why galena feels surprisingly heavy for its size while chalcopyrite feels lighter, teaching real mineralogical concepts.

●

Three-Suspect Elimination

Apply your test results to narrow down three mineral candidates to a single correct identification. Each case provides clear evidence, teaching logical deduction alongside geological knowledge.

☆

Calendar-Based Specimens

Receive one new mineral challenge daily, synchronized to your device date. The same specimen appears for all players worldwide, creating a shared learning experience across time zones.

◉

Streak Preservation System

Build week-long and month-long identification streaks by solving consecutive daily challenges. Track your progress with visual indicators and maintain your geological learning momentum.

How the Testing Works

Visual Mineral Rendering

The application displays three-dimensional mineral specimens using realistic surface textures and lighting. Each specimen shows authentic visual characteristics: pyrite's brassy metallic luster, galena's cubic cleavage planes, and chalcopyrite's irregular surfaces.

Touch-Based Assay Mechanics

You perform tests by dragging your finger across the screen. The scratch test requires a horizontal swipe motion to simulate scraping glass against the mineral surface. The streak test uses a similar gesture against a virtual porcelain plate. Each interaction provides immediate visual feedback.

Progressive Case Structure

The tutorial begins with a guided first case, walking you through both testing methods before presenting three mineral options. Subsequent cases maintain this rhythm: perform two assays, then identify the specimen from three choices based on hardness, streak, and crystal form.

  • Each specimen remains available for 24 hours before expiring
  • Past specimens can be replayed as practice without affecting streaks
  • Field course contains six chapters with increasing difficulty
  • Tray system stores all successfully identified minerals
  • Sample cases demonstrate what completed identifications look like

Mineral Database

  • Pyrite features hardness of 6 to 6½ with greenish-black streak
  • Galena shows hardness of 2 to 2½ with distinctive gray streak
  • Chalcopyrite rates 3½ to 4 hardness with greenish-black streak
  • Each mineral displays accurate crystal formation characteristics
  • Properties match real-world geological reference materials
  • Additional minerals unlock through field course completion

About the Developer

The development team focused on creating an educational experience that teaches genuine geological testing methods.
