About this item

Unearth hidden treasures and explore the science of geology with the NOVA Obsidian Excavation Lab! Young scientists chip and chisel away at a mysterious obsidian replica to reveal a collection of real gems, rocks and minerals. With each discovery, kids learn how to identify their finds using real gemologist methods—matching, testing and classifying stones just like the pros. Once all the stones are uncovered, builders can apply their new excavation and identification skills to the bonus miniature obsidian dig for even more hands-on exploration. Designed to inspire curiosity and confidence, this engaging science kit introduces geology basics through tactile, rewarding play.
