Grade 8 Week 8: Geologic Time Scale

This week we take what we have learned about fossils, relative and absolute age, of earthquakes and volcanoes, and all changes to the Earth to describe Earth's history in what we call the Geologic Time Scale.

How are fossils and other evidence used to describe the geologic time scale?
What trends do we see over the whole geologic time scale?




This week's contract asks you to continue the construction of our class Geologic Time Scale.
