Relative Dating of Geologic Materials
Steve Mattox, Grand Valley State University
This lessons allows students to constuct the basic principals used to understand relative geologic time and the skills used to construct the geologic time scale.

A LONG, LONG time ago: geologic timescales
Elizabeth Johnson, James Madison University
Students compare their pre-conceived impressions of events on the geologic time with the actual positions of these events on a 45.5' geologic timescale.

Lifelines and "Earth lines"
LeeAnn Srogi, West Chester University of Pennsylvania
This activity can be used as a first lab for an introductory-level geoscience course. It is a cooperative ice-breaker gets students to know one another and opens discussion for geologic time and earth history.

Random Walks, Evolutionary Trends, and Branching Models of Diversification
Thomas Olszewski, Texas A & M University
Students are exposed to the concept of random walk and how stochastic processes can be applied to constrain interpretation of diversity trends through geologic time.

Reef Builders through Time
Peg Yacobucci, Bowling Green State University-Main Campus
Students will use the Paleobiology Database (PBDB) to explore the history of reef-building animals through time. They will document diversity and extinction patterns through time for seven reef-building marine ...

Hierarchical Alignment of Timelines
Ilyse Resnick, University of Delaware
In the hierarchical alignment activity students progressively and hierarchically align scale information to a spatial linear representation. The progressive alignment of scales may alleviate the conceptual ...
