How to Make Salt Dough Bug Fossils
Step 1: Preheat and gather
Preheat your oven to 200 degrees Fahrenheit. Having everything laid out makes the process smooth and keeps little helpers engaged.
Step 2: Make the salt dough
In a bowl, combine the flour and salt. Stir to mix. Add the water and stir until a dough ball forms. Knead with your hands until the dough is smooth and fully combined.
Step 3: Roll and cut circles
Place parchment paper on a flat surface. Roll the dough out to about ¼ inch thickness. Use a round biscuit cutter or cup to cut circles. Remove the excess dough, leaving just the cutouts on the parchment paper.
Step 4: Press in the bugs
Press a plastic bug firmly into each circle. Gently lift it straight up to reveal the imprint. Repeat until each round has a fossil design. Transfer the parchment paper with fossils onto a cooking sheet. Bake for 1 hour. Flip the fossils and bake for another hour. Allow them to cool completely before handling. Paint if desired.
All done!
Your fossils are ready to explore!

How to Set Up the Bug Fossil Sensory Bin
Fill a large plastic bin with your chosen sensory base. A light colored filler works especially well because it makes the fossils stand out beautifully. Bury the salt dough fossils throughout the bin, leaving just a few slightly visible so children can “discover” them. Scatter in plastic bugs and decorative stones to add layers of interest.
Add small tools like scoops, brushes, or sifters to encourage digging and fine motor work. Instant excavation station.
