Let each student in your classroom be an archeologist with this fun science activity. Place a geode in a bag or sock and hit it firmly with a hammer to break open (not included). Geodes may contain colored rock or sparkling crystals! What treasure will you find? Adult supervision required. Geode size and contents may vary. Please note that because these are natural rocks, results will vary and they may not all contain crystals.
