If you have a dinosaur-loving toddler or preschooler at home, this Dinosaur Excavation Bin is the perfect way to channel their curiosity into a fun, educational activity. Inspired by our indoor “sandcastle” sensory play (from my End of Summer activity kit), this dino-themed version uses the same materials in a whole new way.
Bonus: It blends sensory exploration with early science skills. Total mom win.
Supplies You’ll Need
Here’s what we used to make our dig site, with some of our favorite Amazon finds linked below:
Cloud dough (DIY: 1 cup flour + 1/4 cup oil) – or use Kinetic Sand for less mess
A bin or tray – this one with a locking lid keeps things tidy
Dinosaur toys – these mini dinos are more like gems. These are mini dino skeletons are perfect for burying
Mini shovels, brushes, scoops, or tweezers – we use these tools for other projects as well!
Optional: “dino” eggs, “bones,” rocks, or fossils
Why It’s Great for Toddlers and Preschoolers
Hands-on learning – helps build attention span and focus
Early science/STEM exposure – introduces excavation and observation
Boosts fine motor skills – digging, scooping, brushing
Creative, screen-free fun – indoors or out
Tip: Cloud dough is safe if tasted, but best for ages 3+ who won’t try to eat it.
How to Set It Up
Mix up your cloud dough or pour in kinetic sand.
Bury dinosaurs, bones, rocks, and eggs in the bin.
Provide tools for your child to "excavate" the items.
Encourage storytelling: What did they find? What’s the dino’s name?
Add a magnifying glass or “field notes” notebook for extra learning fun!
