Geodes

A geode is a stone with a hollow space inside lined with crystals or mineral matter. Most geodes have calcite, quartz, or fluorite crystals, but some may also have pyrite.  Most geodes are between 1 and 12 inches in diameter.

A nodule is a geode that has filled completely with deposited minerals, leaving no hollow in the middle.

Third grade geologists cracked geodes open in lab.  The lab was held inside because of the rain.   We put the geodes inside socks for safety.  Some of the geodes were difficult to crack, so we will take those outside and try again at recess.



A geode reminds us of God’s love.  Although others judge us by our appearance, God values our heart and the beauty within us. “For the LORD sees not as man sees: man looks on the outward appearance, but the LORD looks on the heart.”  1 Samuel 16:7
