A relative age dating activity

Paleontologists still commonly use biostratigraphy to date fossils, often in combination with paleomagnetism and tephrochronology.A submethod within biostratigraphy is faunal association: Sometimes researchers can determine a rough age for a fossil based on established ages of other fauna from the same layer — especially microfauna, which evolve faster, creating shorter spans in the fossil record for each species.Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand.

This activity was developed for use in a high school (grades 9-12) earth science class.It is also appropriate for an introductory level college geoscience class. The Relative Dating Lecture prepares students to be able to rank the images in the Relative Dating Activity from youngest to oldest and how to apply this to the formation of seamounts and volcanic islands.Based on the information presented in the lecture, students should be able to rank the images of island and volcanic processes from youngest to oldest.They will excavate a hypothetical archaeological site from their school yard, make observations, and write an interpretation of the history of the area based on the evidence they will excavate.To facilitate the activity, the teacher will provide some introduction to absolute dating principles through the Half Life of M&M Worksheet.
