In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years). From working with the timeline, learners will understand that humans have been living on Earth for a relatively short time compared to how long life has existed on our planet. The activity can be extended by having learners do their own research of events on the timeline and adding their own descriptions or illustrations to timeline events. This activity can be found on pages 33-34 of the activity guide. [Activity is publicly available through a web crawler capture on Archive.org.]
