Unleash the Paleontologist Within: DIY Dino Bone Dig with Sand and Cornstarch

Unleash the Paleontologist Within: DIY Dino Bone Dig with Sand and Cornstarch

Do you have a budding paleontologist at home or simply a dinosaur enthusiast? Embark on an exciting adventure as we guide you through the process of creating a DIY dino bone dig using sand and cornstarch. This hands-on activity will not only provide hours of fun but also encourage imagination, problem-solving, and scientific exploration. Get ready to unearth ancient fossils and bring the world of dinosaurs to life!

Materials Needed:

To create your own dino bone dig, gather the following materials:

  1. Play sand: You can find play sand at most hardware stores or online. Opt for a fine-grained sand for better results.
  2. Cornstarch: Available in grocery stores, cornstarch will help create a molding mixture that holds its shape.
  3. Water: Plain tap water will be sufficient for mixing the sand and cornstarch.
  4. Plastic dinosaur bones or toys: Look for plastic dinosaur bones or dinosaur toys with detachable parts. You can find them at toy stores or online.
  5. Mixing bowl and spoon: Use a bowl and spoon for mixing the sand, cornstarch, and water to create the molding mixture.
  6. Shallow container or tray: Find a shallow container or tray to contain the dino bone dig. A plastic storage bin or baking tray works well.


Follow these steps to create your own dino bone dig:

  1. Prepare the molding mixture: In a mixing bowl, combine the play sand and cornstarch in a ratio of approximately 3 parts sand to 1 part cornstarch. Mix them together until well combined.
  2. Add water: Slowly add water to the sand and cornstarch mixture while stirring continuously. Add water gradually until you achieve a moldable consistency. The mixture should hold its shape when pressed but not be too wet.
  3. Mold the mixture: Take a handful of the molding mixture and press it firmly into the shallow container or tray. Create hills and valleys to mimic the terrain of a dinosaur dig site.
  4. Bury the dinosaur bones: Place the plastic dinosaur bones or toys within the molded sand and cornstarch mixture, partially burying them to mimic fossils buried in the earth.
  5. Let it dry: Allow the dino bone dig to dry completely. This may take a day or two, depending on the thickness of the mixture.
  6. Excavate the bones: Once the molding mixture has dried, it's time for the excavation! Equip your little paleontologist with small brushes, spoons, or plastic tools to carefully dig and uncover the dinosaur bones hidden within the sand and cornstarch mixture.

Safety Tips:

While this activity is generally safe, it's important to keep a few safety tips in mind:

  1. Adult supervision is recommended, especially when handling small plastic toys or using tools for excavation.
  2. Avoid inhaling or ingesting the sand and cornstarch mixture.
  3. Clean and dry hands before and after the activity to maintain hygiene.

Creating a dino bone dig using sand and cornstarch is an engaging and educational activity that sparks imagination and curiosity. By molding the mixture, burying dinosaur bones, and excavating them, children can experience the thrill of being a paleontologist and discover the wonders of the prehistoric world. So, gather your materials, embrace the adventure, and let the excavation begin as you uncover the fascinating world of dinosaurs right in your own home!
