What would a unit on dinosaurs be if it did not include fossils? Your Lil’ is going to love making their own fossils and as a bonus, this activity works as the prep for a few other activities this month!
We are going to create 3 kinds of fossils: bones, imprints, and dino bodies.

Lil’ Explorers Focus Skills

Science

  • Pose “what” and “why” questions about their surroundings
  • Understand 3 of the 5 senses to make observations

Engineering

  • Construct models to represent their imagination and objects in the world
  • Use tools with appropriate safety and purpose
  • Engage in problem solving activities

Fine Motor Skills

  • Coordinate the use of arms, hands, and fingers together to manipulate objects with increasing accuracy
  • Engage in activities that require hand-eye coordination

Lil’ Creators Focus Skills

Science

  • Pose “what,” “why” and “how” questions about their surroundings
  • Use 5-senses to make observations

Engineering

  • Construct models to represent their imagination and objects in the world
  • Use tools with appropriate safety and purpose
  • Engage in problem solving activities

Fine Motor Skills

  • Coordinate the use of hands, wrists, and fingers to complete tasks that require more precise movements
  • Engage in activities that require hand-eye coordination with increasing accuracy

Required Materials

*Affiliate Link

*Flour

*Salt

Water

*Dinosaur Cookie Cutter

Step #1
Make a salt dough by mixing together:
  • 2 cups flour
  • 1 cup salt
  • 1 cup water
This is a great opportunity for your Lil’ to work on life skills like cooking and measuring without the risk of you having to eat something a little less than edible.
*You can skip this step and use premade Play Doh, but we will be drying out our creations which means your Play Doh will NOT be able to be reused.
Step #2
Bones
  • Roll out a piece of dough
  • Add a small round piece at each end of the roll
  • Pinch the round ends a little so that it looks like the top of a heart.
  • Repeat this process 4-5 times so that you have all different sized fossils for our Comparing Fossils activity.
Step #3
Imprints
  • Grab a small piece of dough and flatten it like a pancake.
  • Press a a toy dinosaur into the dough
  • Lift the dinosaur out of the dough and admire your dinosaur imprint.
  • These will be used in our Excavating Dinosaurs activity.
Step #4
Dinosaur Body Fossils
  • Flatten out a large piece of dough
  • Use a dinosaur cookie cutter to cut out a dinosaur body
  • Cut this dinosaur into a few different pieces (that will be easily put back together)
  • Repeat this process 2-3 times and let it dry out for our Dinosaur Reconstruction activity (Lil’ Creators only, but Lil’ Explorers can certainly still make them).

Teacher Tip

While you are making the fossils with your Lil’ talk about the dinosaurs and how their fossils were made. I explained it to my Lil’ like this:

When dinosaurs died, their bodies were lying in the sand and were covered in dirt. This left an imprint of their body in the sand and left their bones buried for paleontologist to find.
