Bread Fossils

We are going to use bread to represent the ground and soil layers and the sediment that layers on top of the soil over thousands of years. The jelly sweets will represent our animal remains that die on top of the soil and are preserved by the layers over time.

  1. Begin with a slice of bread at the bottom.
  2. Place a few sweets on top of this slice of bread to represent your fossils.
  3. Add another soil layer using bread.
  4. Perhaps now, you can add minerals and different sediments using things like chocolate spread, peanut butter or jam. This shows how many layers form over a long period of time.
  5. Now, we need to add pressure. Place your fossil ‘sandwich’ in a plastic bag and sit on it! Or, you could add books to add weight on top.
  6. If you want, leave your model for two days – this represents 100 million years of time!
  7. Now, it’s time to extract and observe your fossils. If you have it, use a straw to extract a sample and look at the layers of soil.
  8. Now, try to separate the layers of bread, can you find the impression of your fossils?
