In this quick and inexpensive tutorial, we are going to show you how to make a Fantastic Fluorite Fun excavation activity. These excavations are super easy to make and are a great teaching resource to include in your next lesson or discussion about rocks, minerals, geology, and more.

Plaster of Paris


Mixing Bowl

Wooden spoon

Measuring cups

Popsicle sticks – Popsicle sticks are inexpensive, readily available, and make great excavation tools.

Safety goggles or glasses – You we need to provide or borrow a set for each student.

Optional – Brushes and magnifying glasses.

Fluorite - You can buy rough fluorite inexpensively online. Fluorite is beautiful and is seemingly glows under UV light which is super cool for young Excavating Adventurers to explore and investigate.  

Any small container that will fit your specimens and allow room for the plaster mixture will work. I love rummaging through recycle bins for fun and unique containers I can use for excavations. For this tutorial I will use a Chinese food take out container.

  1. Rinse out the Chinese food take out container.
  2. Place the fluorite in the container.
  3. Mix 1 cups sand with 1/3 cup Plaster of Paris.
  4. Add 1/3 cup of water and mix until you have a pancake batter consistency.
  5. Pour the mixture over the fluorite.
  6. Place the Fantastic Fluorite Fun excavation in front of a fan overnight until it is completely dry. 
  7. Cut and peel the Chinese food container away from the excavation. Place the excavation back in front of the fan if it is still wet. 
  8. Optional - You can leave the excavation in the Chinese food container. Leaving the Fantastic Fluorite Fun excavation in the container looks really cool and even has the little metal carrying handle. 
  9. Distribute the excavation, excavation tools, and safety goggles to your Excavating Adventurer and have fun watching them dig in and discover the awesome fluorite you have hidden inside.
  10. Clean the fluorite. Then in a dark space, have your Excavating Adventurer shine the UV light on the specimens.
