It’s time to work on our paleontologist skills and excavate some fossils! This sensory bin kept Rea engaged and excavating fossils for over 30 minutes. We are using our homemade fossils from our Making Fossils activity yet again, and because I always like to add a little literacy to sensory bins, I added magnet letters to a the mix.

*Baby Oil

*Plastic Tub

*Magnifying Glass

*Magnet Letters

*Paint Brush

Step #1
Start by making your own moon sand in the plastic tub (sensory bin). I used Tinkerlab’s recipe.
  • Combine 4 cups of flour with 1/2 cup of oil.
  • Mix and play.
I have never played with store bought moon sand so I cannot compare, but I really liked playing with this! It felt so nice and was great for molding.
Step #2
Print out the Dinosaur Letter Excavating Template.
Step #3
Bury your fossils in the moon sand.
These are the fossils you made during the Making Fossils Activity.
Step #4
Bury some magnet letters in the sand.
  • Lil’ Explorers are focusing on Q, V, X, Y, and Z this month.
  • Lil’ Creators are focusing on A-Z this month.
Step #5
Invite your Lil’ to excavate the fossils and letters using a paint brush and magnifying glass. As they excavate and discover the letters, match them to the Dinosaur Letter Excavating Template.

Teacher Tip

This activity can be messy. For this reason, I encourage you to do it outside or be prepared with your vacuum.
