This activity helps to show how fossils provide information about living things that inhabited the Earth in the past. It includes a short video, which explains what fossils are and how they are formed and shows how to make a replica fossil using dinosaur footprints and Plaster of Paris.

A follow on activity shows how to create a model of rock layers with fossils in them using different coloured jelly. Layers can be added each day in the classroom to give children a clearer picture of the fossilisation process. It also helps to show how the age of the rock relates to the age of the fossil you find in the rock, the fossils found at the bottom being older than the fossils found in the layers at the top.
