Teachers, save “Geologic Era - Tree Map” to assign it to your class.

Students will classify the Geologic Eras (Paleozoic, Mesozoic, and Cenozoic) and include events of those eras, include a drawn picture and the source of their information. Also, students will add a VOICE RECORDING to explain their Tree Map (thinking map) Additional resources: 1. https://docs.google.com/presentation/d/1pjY6J0JqEOZNxaYRdkolVBE1TCx5NVJuueaqWmfNDds/edit?usp=sharing 2. https://www.ck12.org/c/earth-science/geologic-time-scale/lesson/Geologic-Time-Scale-MS-ES/?referrer=concept_details "Earth formed 4.5 billion years ago. Geologists divide this time span into smaller periods. Divisions in Earth history are recorded on the geologic time scale. For example, the Cretaceous ended when the dinosaurs went extinct. Many of the divisions mark major events in life history. The largest blocks of time on the geologic time scale are called “eons.” Eons are split into “eras.” Each era is divided into “periods.” Geologists may just use “early” or “late.”
