Can you remember how rocks are formed? Invite children to share their ideas, then go through the slides about the rock cycle and the different types of rock (i.e. igneous, sedimentary and metamorphic).
Show children the picture of a fossil on the slides. What is this? Go through the information on the slides about how fossils are formed.
Show children the pictures of different fossils on the slides. What do you think we can find out from these fossils? Discuss ideas then explain how palaeontologists use fossils to help them find out about living things from millions of years ago.
