Diatomaceous earth (DE) isn’t just a useful household item—it can also be the star of a creative and educational DIY project for kids. A dinosaur dig kit is a hands-on way to spark curiosity about paleontology and science, and with DE, you can craft a safe and natural version right at home. This step-by-step guide will show you how to create a fun, memorable activity that kids will love.
Why Use Diatomaceous Earth for a Dig Kit?
Diatomaceous earth is an ideal material for crafting a dig kit because:
Texture: Its fine, crumbly texture mimics natural sediment, making it perfect for excavation.
Non-Toxic: When using food-grade DE, it’s safe for kids to handle.
Eco-Friendly: DE is a natural, sustainable material, aligning with green living principles.
Materials You’ll Need
For the Kit
Food Grade Diatomaceous Earth
Plaster of Paris
Small dinosaur toys, fossils, or bones (plastic or resin replicas work well)
Large mixing bowl
Water
Measuring cups
A small container or mold (plastic trays, shoeboxes, or baking pans)
For the Dig Tools
Small paintbrushes
Wooden skewers, toothpicks, and small chisels
Magnifying glass
Safety goggles (for added realism and safety)
Step-By-Step Guide
Step 1: Prepare the Mold
Select a mold that will hold the DE mixture. A shoebox or plastic tray works well for a larger kit, while smaller containers can create individual-sized dig kits.
Place your dinosaur toys or fossils in the mold, arranging them to be partially buried or fully hidden in the final product.
Step 2: Mix the Digging Material
In a large mixing bowl, combine 2 parts diatomaceous earth with 1 part plaster of Paris.
Gradually add water while stirring until the mixture has a thick, mud-like consistency. Aim for a pourable texture but not too runny.
Optional: Add a few drops of food coloring to the mixture to make the "sediment" more visually appealing.
Step 3: Fill the Mold
Pour the DE and plaster mixture into the prepared mold, covering the toys or fossils.
Tap the mold gently on a flat surface to remove air bubbles and ensure even coverage.
Smooth the surface with a spatula or spoon for a uniform appearance.
Step 4: Allow It to Set
Let the mixture dry and harden completely. This typically takes 24–48 hours, depending on the thickness.
Once hardened, carefully remove the dig kit from the mold.
Step 5: Set Up the Digging Station
Provide the kids with small paintbrushes, wooden skewers, and a magnifying glass.
Place the dig kit on a tray or in an area where messes are easy to clean up.
For added fun, include a “digging license” or excavation certificate as part of the activity.
Educational Tips for the Activity
Explain Sediment Layers: Talk to kids about how fossils are found in layers of sedimentary rock and how paleontologists use tools to uncover them.
Dinosaur Facts: Share fun facts about the dinosaurs or fossils hidden in the kit to make the activity more engaging.
Encourage Observation: Have kids use a magnifying glass to examine the texture of the DE and discuss its natural origins.
Safety Tips
Always use food grade DE to ensure safety during handling.
Work in a well-ventilated area or outdoors to avoid inhaling dust during mixing.
Ensure that younger children are supervised to prevent accidental ingestion.
Be sure your children are wearing gloves and also eye protection. Makes it safe and easy for cleanup.
Customizing Your Dig Kit
Themes: Switch up the theme by using gemstones, ancient artifacts, or marine fossils instead of dinosaurs.
Personalized Kits: Create individual dig kits for party favors or classroom activities.
Decorative Touches: Paint the dried block to resemble real rock or sediment for added realism.
