Salt Dough Fossil Art

Press natural objects into salt dough to create durable fossil-inspired relief art while exploring texture, evidence, and earth science.

What You Will Create

A flexible, hands-on build.

Press natural objects into salt dough to create durable fossil-inspired relief art while exploring texture, evidence, and earth science. The guide can be adapted for families, classrooms, clubs, or drop-in learning spaces.

Get Ready

Supplies and preparation

Supplies

Gather these materials

  • Pre-mixed salt dough
  • Rolling pins
  • Leaves, shells, small figures, or other textured objects
  • Wax paper or placemats
  • Toothpicks or skewers
  • Paper towels

Preparation

Before participants begin

Mix the dough before participants arrive and divide it into individual portions. Wash and dry natural objects. Protect the work surface and decide whether pieces will air-dry or be baked later by an adult.

Use only clean, non-sharp objects. An adult should manage any oven drying. Remind participants that the dough is a craft material and should not be eaten.

Build Guide

Follow the steps

Test as you build. Small revisions are part of the process and help participants understand why the final design works.

1. Plan and prepare

Place a portion of dough on wax paper and roll it into a disk about 1/2 inch thick.

2. Build the foundation

Arrange one or more objects on the surface and press firmly without cutting through the dough.

3. Add the main feature

Lift each object straight up to reveal the impression. Try a second arrangement if the first impression is unclear.

4. Test and adjust

Add a name, date, border, or small details with a toothpick. Make a hanging hole before drying if desired.

5. Finish and reflect

Move the piece on its wax paper to a drying area. Air-dry fully or have an adult bake it using the dough recipe’s directions.

Keep Exploring

Try another direction

Use one of these extensions after the first version is working.

  • Compare impressions made by smooth and textured objects.
  • Create a mystery impression and ask a partner to identify the object.
  • Paint the dry relief with a thin wash to emphasize the recessed texture.
