Make a Coffee Dough-Based Fossil Science Experiment materials
1 Make a Coffee Dough-Based Fossil Science Experiment Mixing_Kneading ingredients together(7)

Mix the ingredients together and knead the dough until soft.

2 Make a Coffee Dough-Based Fossil Science Experiment Spread dough on baking paper

Spread the dough onto wax paper and cut round shapes using a knife, jar, glass or cookie cutter.

3 Make a Coffee Dough-Based Fossil Science Experiment - Pressing shapes in mold

Press objects into the soft dough to make ‘fossil’ impressions.

4 Make a Coffee Dough-Based Fossil Science Experiment - End result

The dough can be left to harden overnight.

Why Does This Happen

The impression can be of a bone, skin, egg fragment or tooth. Once the mud hardens into stone the impression is preserved, hopefully avoiding erosion from water and wind so that palaeontologists get to look at the impression.

Dinosaurs aren’t the only fossils found in rocks. All manner of living things can be found if you know where to look. Try going for a walk along a rocky headland next time you’re at the beach. If you look into these rocks you can often find impressions of ancient marine organisms.
