In this activity (p.7-8 of PDF), learners examine fossil formation. Learners investigate the stages in the formation and finding of fossils: erosion, sedimentation, creatures dying and being buried, fossilization of hard remains, and scientists uncovering fossils. Use this activity to discuss how fossils, and our knowledge of the rocks in which we find them, are scientific evidence for how animals and plants looked millions of years ago and provide solid evidence for evolution.
