Absolute dating lesson plan

In a way this field, called geochronology, is some of the purest detective work earth scientists do.

There are two basic approaches: relative age dating, and absolute age dating.

Depending on the number of different colored beads you have available, you can do just one or several different isotopes.

Each isotope you choose needs two different colors of beads associated with it and the total of number of beads per bag will be 100 (this creates the simplest math, but you could use less beads and have them calculate percentages if necessary).

Then in Phase 2 of the project, the teacher will provide the students with plastic bins each representing a different stratum of the archaeological site.

Using the absolute dating principles provided in Phase 1 of the lesson, students will make decisions of which artifacts to send to a lab for absolute dating.

The age of fossils can be found using relative dating or radiometric dating, which is also called absolute dating.

Radiometric dating involves using radioactive elements and their half-lives to figure out the age of the fossils.

Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate. The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating. Based on this information, they will learn how to relatively date associated artifacts.They will interpret their archaeological site by writing an explanation of when each stratum and artifact was deposited in their site.
