Activity 1: Do at School!
Make a fossil sandwich
Bones and shells must be buried by sand or mud to become fossils.
Making a fossil is a bit like making a sandwich.
The bread is soft mud at the bottom of a pond.
The sandwich filling is made of different creatures.
Now make your own fossil sandwich!
Discuss: In what ways is this fossil sandwich not realistic?
Main Message: This exercise shows how fossil organisms and their impressions are formed within layers of sediment. It also shows that some objects are better preserved than others.
