Popsicle stick, wooden dowels, brushes, magnifying glass, and safety goggles. These will be the excavation tools and safety equipment your Excavating Adventurer will need to explore and enjoy their excavation.

Assorted bag of mixed fossils. These can be purchased online. You can also use fun little plastic dinosaurs.

  1. Spread the fossils out in the bottom of the aluminum pie pan.
  2. Mix 3 cups sand with 1 cup Plaster of Paris.
  3. Add 1 cup of water and mix until you have a pancake batter consistency.
  4. Pour the mixture over the fossils in the pan.
  5. Gently tap the sides on the pie pan to settle and level out the mixture.
  6. Optional – Once the mixture begins to set and firm up (usually after 8-10 minutes), place little plastic dinosaurs on the surface of the excavation.
  7. Place the excavation in front of a fan overnight until it dries completely.
  8. Once the excavation is dry, distribute the excavation tools and safety goggles and let your Excavating Adventure dig in and discover the treasures you have hidden inside.
