Teaching geologic time and rates of landscape evolution with dice
Kate Ruhl, Massachusetts Institute of Technology
Landscape evolution provides a convenient framework for understanding geologic time and rates because students can observe how processes like erosion and deposition shape their surroundings. In this example, students build 3-D sandbox models based on topographic maps and design and stage a "virtual adventure race." Sandbox landscapes are used to illustrate erosional processes,while local examples are used to discuss landscapes as transient or steady over different time- and length scales. Dice experiments illustrate radioactive decay and the shape of the age equation curve, and 14C dating, geochronology and thermochronology are introduced as "stopwatches" that start when a plant dies, a crystal forms, or a rock nears the surface and cools to a certain temperature. The sandbox model and thermochronometer "stopwatches" are combined to measure erosion rates and rates of landscape change. Ultimately, model rates (cm/hour) calculated from stopwatch times on the order of seconds can be related to geologic rates (km/My) calculated from real million-year-old samples.
Implementing A Constructivist Teaching Model For Conceptualizing Geologic Time
The activity fosters middle learning students critical thinking and allows for student generated essential questions to further their understanding of Earth's history and geologic time.

BotEC: The Magnitude of Geologic Time
Question The oldest rock yet to be found on the earth is from Canada and is radiometrically dated at 3.8 billion years old. Various lines of evidence suggest that the earth is about 4.5 to 5 billion years old. A ...
Driving Through Geologic Time - An analogy
Eric Baer, Highline Community College
An analogy of the Earth's history to a cross-country drive.
My Geologic Address: Locating Oneself in Geologic Time and Process
Kip Ault, Lewis and 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.
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.
Illinois through time
Surangi Punyasena, University of Illinois at Urbana-Champaign
This assignment serves as an introduction to geologic time, using Illinois as an example. It uses the Paleo Portal website to illustrate each geologic period.
