How Do We Know What Plants and Animals Were Like Long, Long Ago?
Fossil evidence can tell us how ancient and present-day organisms change over time.
Students hear about the discovery of an amazing fossil on “Mirounga Island.” They then watch a video to learn how fossils are formed and predict which parts of real-life organisms might be preserved by fossilization. Students figure out together why scientists were so excited by the fossil they uncovered.
