Strategy: After watching the Earth timeline video students launch into the question, “How do we know how old the stuff we find as fossils really is?” Relative dating techniques and absolute dating techniques are discussed. Videos complement the investigation. Students are given fossils and asked to determine the approximate age of the fossils using tools such as charts and tables.
