Geologic Time Period. The geologic time scale is a representation of the Earth’s history. It organizes Earth’s history by major changes or events that occurred, using evidence from the fossil and geologic records. The time scale is divided into periods based on the order in which different groups of rocks and fossils were formed.

Approximately 30 students, divided into groups covering 11 time periods, will construct a 4.6-billion year timeline. Each group will research one geologic period’s biologic and geologic events and artistically render them on the class timeline. This will allow them to experiment with different materials in 2-D and 3-D.
