Creating a Model of a Fossil

We created a model of a fossil in a class demonstration.

  1. We warmed the clay by rolling it in our hands
  2. We put petroleum jelly on the shell to keep it from sticking
  3. The shell was pushed into the clay
  4. The shell was gently pulled out keeping as much of the shape as possible
  5. Ms. Herbert mixed the Plaster of Paris and poured it into the clay molds
  6. We had to let it sit for a while and harden
  7. The clay was gently pulled off

In the comments below, explain how the formation of this model is different from formation of a real fossil. Sign the entry with your pseudonym (pen name).

    A real fossil is diffrent from a model of a fossil because it is white and they used glay and plast of peris and they used something else for the real thing I dont know but they used somethig else
