Learning Target:
1. I can demonstrate knowledge of the vocabulary terms.
2. I can know the correct sequence and dates of major eras of geologic time.
3. I can name a representative fossil for each era.
4. I can use a key to match fossils with the appropriate era and period of geologic time.
5. I can interpret fossils, being able to name the fossils and to infer the environment represented.
6. I can use principles to relatively date (put in order) a sequence of events.
7. I can use the principles of radiometric decay to absolutely date a sample.
