Now we are going to link what we did with our own timelines to new information about the Geologic Timescale.
LEARNING OBJECTIVE: 6-8.ESS1.C.1 – Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s history.
- We can create a time scale of our own lives.
- We can summarize major events in Earth’s history.
- We can recognize patterns to understand how time is divided on the geologic time scale.
