Your Challenge: Create your own fossils to study and explore.
What You Need
- Modelling Clay
- Mold clay into a flat shape.
- Lightly press then remove the object(s) from the clay + fill hole with white glue.
- Let dry overnight, then carefully peel back the glue shape from the clay.
- Neaten your fossil by cutting off edges.
Take It Further
Turn your fossils into a fun game with friends! Lay out your fossils and have friends guess what object(s) left each shape.
How It Works
When an animal or plant dies, its remains may be buried by sand and mud. Over time, the sediment turns into rock, and the original material dissolves. Then minerals crystallize inside the rock mold left by the original object and form a fossil. In your demonstration, the glue acts as the rock that has formed over millions of years to create a likeness of your object.
- Over 1000 different species of dinosaurs have been named and the list continues to grow as new fossils are discovered.
- The oldest fossil known is of blue-green algae that lived on the banks of South Africa 3.2 billion years ago.
- Fossil facts are always being updated. Currently, the oldest dinosaur is said to have lived in Madagascar 230 million years ago.
- Fossil fuel does not come from dinosaurs, as many people believe, but from the fossilized remains of tiny organisms, called diatoms.
- The study of fossils is known as paleontology. Fossils are considered to be one of the most important tools to understand the geological changes on Earth over millions of years.
