Grade 8: Week of January 3rd-7th

We begin our new unit on geologic, biological, and technical change, which comprises 20-25% of questions on the end of grade test. We will examine how scientists determine the age of rocks through radioactive dating and relative dating to give us our geologic time scale. Students will correlate fossils with different eras and learn about the laws of geology: the law of Horizontality, the Law of Superposition, and the Law of Cross Cutting Relationships. Students will apply these laws and study examples of the Grand Canyon and the Stawamus Chief in British Columbia, Canada. Then we will make our own geologic model and other groups will need to decipher the geological processes that occurred there to change the landscape over time.
