  1. Place the shark teeth in the tin.
  2. Mix 1 cup sand with 1/3 cup Plaster of Paris.
  3. Add 1/3 cup of water and mix until you have a pancake batter consistency.
  4. Pour the mixture over the shark teeth.
  5. Fill the tin nearly to the rim. You will want to leave a little space so the lid will close once the excavation is dry. 
  6. Optional - Decorate the surface of the excavation with a little glitter. 
  7. Place the Shark Week Tooth Dig in front of a fan overnight until it is completely dry.
  8. Distribute the excavation, excavation tools, and safety goggles to your Excavating Adventurer and have fun watching them dig in and discover the awesome shark teeth you have hidden inside.


Shark Safari: Dive into the World of Fascinating Fish Predators!

Fun Facts about Sharks:

  1. Sharks are ancient creatures that have been swimming in the Earth's oceans for over 400 million years, even before dinosaurs roamed the land.

  2. There are over 500 different species of sharks, ranging in size from the tiny dwarf lanternshark, which is about the size of a human hand, to the massive whale shark, which can grow up to 40 feet (12 meters) in length.

  3. Contrary to popular belief, not all sharks are ferocious predators. Some species, like the gentle giant whale shark, feed on plankton and are considered filter feeders.

  4. Sharks have an incredible sense of smell, and some can detect a single drop of blood in an Olympic-sized swimming pool.

  5. Their skin is covered in tooth-like scales called dermal denticles, which help reduce friction as they swim and make their skin feel rough to the touch.

  6. Sharks have multiple rows of teeth that they continually shed and replace throughout their lifetime. In some species, they can lose thousands of teeth in a lifetime.

  7. Great White Sharks are often portrayed as fearsome predators, but they have a curious nature and may sometimes investigate objects by bumping them with their snouts.

  8. Sharks play a crucial role in maintaining the balance of marine ecosystems as top predators, regulating populations of prey species and keeping the ecosystem healthy.

  9. Some shark species, such as the bull shark, are capable of surviving in both saltwater and freshwater environments, allowing them to travel up rivers.

  10. Sharks have a specialized organ called the "ampullae of Lorenzini" that allows them to detect electrical fields produced by other animals, helping them locate prey.

  11. Sharks have a sixth sense called "lateral line" that allows them to detect vibrations in the water, helping them navigate and locate prey even in low light or murky conditions.

  12. Many sharks, including the Hammerhead Shark, have distinctively shaped heads called cephalofoils, which may help them with improved maneuverability and enhanced sensory perception.

Remember, sharks are extraordinary creatures that inspire awe and wonder, and learning about them helps us appreciate the diverse and fascinating life in our oceans!
