Objectives of this activity are: 1) To have students determine relative age of a geologically complex area.

Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves.

There are two main methods determining a fossils age, relative dating and absolute dating.

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

This activity on determining age of rocks and fossils is intended for 8th or 9th grade students.

It is estimated to require four hours of class time, including approximately one hour total of occasional instruction and explanation from the teacher and two hours of group (team) and individual activities by the students, plus one hour of discussion among students within the working groups.
