In this quick and easy tutorial we are going to teach you how to make a giant dinosaur egg excavation. This is a really fun way to take a regular old excavation activity and super size it for even more excavation excitement! Your kids will have a blast digging into this dinosaur egg excavation and discovering this treasures you have hidden inside.
  • Giant plastic egg that opens vertically - This will be the mold we use to create our giant dinosaur egg excavation. I bought some giant plastic eggs on clearance after Easter this past year and you can easily find them online for sale. There are also several toys that come in oversized eggs that make perfect molds. Don't worry if you can't find that perfect egg shaped mold. Just get a large container and your children will still love the oversized excavation. 
  • Cooking spray
  • Sand
  • Plaster of Paris
  • Water
  • Container
  • Large wooden spoon
  • Measuring cup
  • Large plastic dinosaur skeleton. Make sure the dinosaur skeleton will fit in your plastic egg.
  • Excavation tools. Wooden dowels and other blunt instruments work well. Sharp tools are unsafe and not necessary as the excavations are reasonably brittle and excavate easily. 
  • Safety goggles
  • Small brush

  1. Put three cups of sand in your mixing container.
  2. Add one cup Plaster of Paris.
  3. Use the wooden spoon to mix the sand and Plaster of Paris.
  4. Add one cup of water and mix.
  5. Keep adding small amounts of water until you reach a pancake like batter consistency. 
  6. Spray the inside of your mold with cooking spray.
  7. Lay your plastic dinosaur skeleton inside the mold.
  8. Pour the mixture into the mold.
  9. Gently tap the sides of the egg mold to remove any air bubbles. This will also allow a little mixture under the skeleton.
  10. Set the giant dinosaur egg excavation somewhere safe to dry undisturbed overnight. I like to put the excavation in front of a fan. 
  11. Once the excavation has dried, gently turn it over onto a flat surface and remove it from the mold. 
  12. Allow the  excavation to dry an additional twenty four hours, preferably in front of a fan.


Now the giant dinosaur egg excavation is ready to be enjoyed. Find an area that is easy to clean up, distribute the safety goggles and excavation tools, and let the excavating begin. 

Cracking the Mysteries: Dinosaur Eggs, Baby Dinos, and Nesting Wonders!


Here's a list of questions about dinosaur eggs, dinosaur babies, and dinosaur nests, along with their informative answers:

  1. Q: How did dinosaurs lay eggs? A: Dinosaurs laid eggs in a similar way to modern-day birds. Female dinosaurs would lay eggs, which were then incubated until they hatched.

  2. Q: Where have dinosaur eggs been found? A: Dinosaur eggs have been found in various places around the world, including Mongolia, China, Argentina, and the United States.

  3. Q: How big were dinosaur eggs? A: Dinosaur eggs varied in size depending on the species. Some dinosaur eggs were as small as a chicken egg, while others were much larger, reaching the size of a soccer ball or even bigger.

  4. Q: How do scientists know what dinosaur eggs looked like? A: Scientists have discovered fossilized dinosaur eggs, which provide valuable clues about their size, shape, and shell structure. These fossils help researchers understand the characteristics of dinosaur eggs.

  5. Q: Did all dinosaurs lay eggs? A: Yes, all dinosaurs were egg-laying creatures. Just like modern reptiles and birds, dinosaurs reproduced by laying eggs.

  6. Q: How did dinosaur babies hatch from their eggs? A: Dinosaur babies, also known as hatchlings, would use a specialized egg tooth or beak to crack open the shell from the inside. They would push their way out and enter the world.

  7. Q: Did dinosaur parents take care of their babies? A: While there is limited evidence of parental care in dinosaurs, some species are believed to have exhibited some level of parental care. It is thought that they may have protected or provided food for their young.

  8. Q: Where did dinosaurs build their nests? A: Dinosaurs built nests in various locations, such as on the ground, in vegetation, or even in burrows. The specific nesting sites varied among different dinosaur species.

  9. Q: How do paleontologists find dinosaur nests? A: Paleontologists search for dinosaur nests by looking for specific geological formations or signs of nesting behavior, such as eggs arranged in a circular pattern or evidence of protective structures.

  10. Q: What do dinosaur nests tell us about dinosaur behavior? A: Dinosaur nests provide valuable insights into the reproductive behaviors and social structures of dinosaurs. They help scientists understand how dinosaurs cared for their eggs and offspring.

Remember, our understanding of dinosaur eggs, dinosaur babies, and dinosaur nests is continually evolving as new discoveries are made and research progresses.


Dino-mite Facts: Exploring the Fascinating World of Dinosaurs


Fun Facts about Dinosaurs:

  1. Some dinosaurs were as small as chickens! The Microraptor, a tiny dinosaur, was only about the size of a crow.

  2. T. rex may have had the strongest bite of any land animal in history. Its bite force was estimated to be more powerful than a modern-day crocodile!

  3. Dinosaurs came in all shapes and sizes. Some had long necks like the Brachiosaurus, while others had sharp horns like the Triceratops.

  4. Not all dinosaurs were meat-eaters. Some dinosaurs, like the Stegosaurus, were herbivores and feasted on plants.

  5. The longest dinosaur ever discovered was the Argentinosaurus, measuring around 100 feet long—that's longer than three school buses lined up!

  6. Did you know that some dinosaurs could fly? The Pteranodon, a type of flying reptile, soared through the prehistoric skies.

  7. Velociraptors were much smaller than they are often shown in movies. They were about the size of a turkey!

  8. Many dinosaurs had feathers! Scientists believe that some dinosaurs, like the Velociraptor and T. rex, had feathers similar to those of modern-day birds.

  9. The Triceratops had the most impressive headgear. It sported three large horns on its face and a frill at the back of its head.

  10. Some dinosaurs may have been really colorful! Fossil evidence suggests that dinosaurs had pigments in their skin, much like modern reptiles and birds.

  11. Dinosaurs ruled the Earth for over 160 million years, from the Late Triassic Period to the end of the Cretaceous Period.

  12. The study of dinosaurs is called paleontology. Paleontologists use fossils and scientific methods to learn about these ancient creatures.

Remember, these facts are just a glimpse into the amazing world of dinosaurs, and there's so much more to explore and discover!
