Uncle Geo and HIs Valuable Florescents   

Picture

        Artie and Callie loved science!  Today they studied about minerals. Mrs. Green, the STEAM  teacher, showed the twins' Uncle Geo's website with his florescent minerals. Their classmates gasped at the beautiful colors. 
       Callie volunteered, "We can bring in a few fluorescent minerals for the class to hold.  We'll bring in a small long ultraviolet light. Everyone can see how minerals in these rocks glow under a black light!"  
        Artie added, "Our Uncle George is a geologist who mines and collects rocks with minerals. They look plain in the sunlight, but they show beautiful green, red, purple, blue, and other glowing colors in the dark with the UV light. These rocks are called fluorescents. They can be worth hundreds or even thousands of dollars."

      Rita, one of the Shoppers, started to tease Callie, “Glow Little Glow Worm! Glow!”  She laughed with two of her friends. The Shoppers earned their name because they "dug" shopping. Their fingerprints linked to their parents' bank accounts. They complained about sore fingers from shopping at stores and online.
       The Shoppers didn’t like to get dirty and never "dug up" anything except trouble. They bought trendy shoes, clothes, games, and electronics in stores and online.  "Money never burned a hole in their pockets" because they never used cash. They never realized how much things cost. The Shoppers' parents tried to punish them for buying too many things, but nothing seemed to slow them down.

      Artie and Callie just raised their eyebrows at each other. The Marble twins  ignored Rita and the Shoppers when they said mean things.

     Mrs. Green said, "That's enough negative remarks. We'd love seeing the fluorescents. I'll call your Uncle Geo and we'll schedule him in with our Speaker Projection.  (This mixed reality system "projected" experts for classroom  presentations.)
