Today we began our quest to determine the ages of rocks & fossils by looking at the Law of Superposition and relative dating.
After that, students began working on a booklet (glued to page 36). This booklet addressed the following areas:
1) ordering layers of rock from youngest to oldest
2) determining what fossils make good and poor index fossils
3) Principles of Geology –
a) Law of Uniformitarianism
b) Law of Superposition
c) Law of Original Horizontality
d) Law of Cross-cutting Relationships
Students were examined multiple diagrams and images of rock strata and answered analysis questions to determine the age of rocks, how rocks have changed, and what geological principles apply to each.

Tomorrow we will be out on a field trip! Students remaining at school will complete a review booklet to reinforce our content on Earth’s history.
See you then,
