Geologic Time
Nicole LaDue, Northern Illinois University
Formative assessment questions using a classroom response system ("clickers") can be used to reveal students' spatial understanding. Students are shown this diagram and instructed to "Click on ...

Geologic Time Resorts
JoAnn Thissen
In this Geologic Time Resorts activity students do in-depth research on a given geologic time period of the Phanerozoic Eon and create brochures "selling" their time period as a resort destination.

Relative and Absolute Geologic Time with Maps and Spreadsheets
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This activity takes place in a laboratory setting and takes ~1.5-2 hours to complete. Students apply stratigraphic principles for relative dating and basic equations of isotopic systems for absolute dating and ...

Geologic Time Scale CogSketch geoscience worksheet
Bridget Garnier
Sketching activity that uses a sketch-understanding program, CogSketch. This worksheet has students build the geologic time scale by adding events on increasing larger scales, from 1 million years to 4.56 billion ...

Counting Critters: Using the Paleobiology Database to track fossil diversity through geologic time
Rowan Lockwood, College of William and Mary
Students learn how to use the Paleobiology Database (PBDB) to develop a diversity curve showing changes in global biodiversity through time. They then use this curve to explore major events in the history of life, ...

Learning Assessment #5 - Geologic Time (2011)
Leslie Reid, University of Calgary; Michelle Speta, University of Calgary
An in-class activity that tests students' understanding of the principles of relative age, absolute age and numerical age bracketing.

Learning Assessment #6 - Geologic Time (2010)
Leslie Reid, University of Calgary; Michelle Speta, University of Calgary
An in-class activity that tests students' understanding of the principles of relative age, absolute age and numerical age dating.

My Geologic Address: Locating Oneself in Geologic Time and Process
Kip Ault, Lewis & Clark College
Students locate their homes on local, regional, and global scale geologic maps. They build up an "address" describing their location in geological terms based on the features of the maps, from local bedrock to regional and global tectonic features.

Global Change in Local Places
DATA: SHALDRIL Core Data; NOAA Pollen data TOOL: GeoMapApp SUMMARY: Import Antarctic sediment core data files into GeoMapApp to create maps and graphs. Use data to infer past climate conditions based on current vegetation distributions.

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.
