Directions:

 

  1. Arrange the condiment cups on the tray making sure you have one for each student. You may want to make a couple extra excavations.
  2. Place some fossils in each 2oz cup.
  3. Mix 3 cups sand with 1 cup Plaster of Paris.
  4. Add 1 cup of water and mix until you have a pancake batter consistency.
  5. Pour the mixture over the fossils.
  6. Gently tap the sides on the tray to shake the condiment cups. This will settle the mixture down, around, and under the fossils.
  7. Place the DIY Classroom Fossil Digs in front of a fan overnight until they are completely dry.
  8. Place a lid on each excavation.
  9. Distribute the excavations, excavation tools, and safety goggles to the students and have fun watching them dig in and discover the awesome fossils you have hidden inside.
