The Fossil Record

Christine just finished learning about the fossil record in her science lessons and the experiment was to make your own fossil cast. She made a cast of a shell and, just for fun, she made one of her fingertip too.

First we make the plaster mud

 Then we pour it in the mold. We made the mold by pressing the shell into plasticine.

 Once it's dry we take the cast out of the mold

 And there it is!

 It looks just like the original!

 ..and this one does too!
