This week, the children brought in fossils from home to help bring our science lessons to 'life'. We are learning about living things, evolution and inheritance and for this lesson focused on how fossils give scientists clues about organisms that lived in the past.
We found out that the oldest fossils are of ancient bacteria and are estimated to be over 3 billion years old. The newest fossils are around 10,000 years old. We also learnt about the formation of fossils and can explain that fossils are not pieces of dead organisms but rather they are impressions or casts of the original living thing, which has decayed away.
