This was a two part activity- both were so much fun! First we made our own dinosaur bones and fossils out of homemade clay, then I buried them in our garden for the boys to dig up. They used shovels and sifters to find the bones and then cleaned them with paintbrushes. I honestly have no idea if they found them all… I’m hoping we discover a few more that were left behind when we plant our vegetables in a few weeks!

What you need:
- Baking Soda
- Cornstarch
- Water
- Measuring Cup
- Pot
- Shovels & Sifters
- Skewers
- String
What to do:
For the clay:
- Mix 2 cups baking soda and 1 cup cornstarch.
- Stir in 1 1/2 cups water.
- Place over medium heat, continuously stirring until it thickens and becomes dough like (about 10 min).
- Let cool and knead – adding cornstarch or (baking soda) as needed to reduce stickiness.
- Use immediately or wrap in plastic wrap and store in refrigerator.
- To make bones we just used our hands and molded until they looked like bones. For the fossil prints we used toy dinosaurs to make footprints and also pressed different parts of their bodies (teeth, tail, etc.) into the clay.
For the dig:
- Find a good plot of dirt and dig to loosen the soil if necessary.
- Use 4 skewers and string to rope off the prepared area.
- Bury your bones and fossils – not too deep!
- Invite your child to be paleontologists and dig for the dinosaur bones.
