Let's Create!

  • Make your salt dough! To do this, first combine the salt and flour in the mixing bowl (a great opportunity for your kids to participate and learn about measurement too)!

  • Slowly add in the water

  • Take turns kneading it until it has reached a good consistency (if it is too sticky, try adding in a bit of flour at a time).

  • Next, roll the dough into 1 inch ball and then flatten onto the cookie sheet.

  •  Press the dinosaur figurines into the dough


  •  Bake in the oven at about 300 for 25 minutes and/or just let it sit (until it hardens).

  • Another option for this project is to create an actual dinosaur skeleton (more challenging option).

  • Print off an image (such as this one) of a dinosaur skeleton. Place it under some plastic wrap.

  • Then have your child place the salt dough over the bones (forming it to look like a skeleton)!

  • Let the dough sit to dry!

  • Sensory Bin Idea!

    • ​Place the fossils in the bin along with sand and paintbrushes. Let your child(ren) experiment with being a paleontologist!
