The Cosmic Calendar
Erika Grundstrom, Vanderbilt University
In this activity, one takes ALL of time, from the beginning of time (i.e., the Big Bang) all the way up to today, but one compresses it into one year. One can do this for all levels of students depending on how ...

Metaphor for the geologic time scale
Cara Thompson
Students choose an object or concept that they are familiar with (e.g., football field, pint of beer, etc) and calculate the cumulative amount of that object or concept that represents intervals of geologic time. ...

Geologic and Navajo Time Line
Margaret Mayer, Dine College
Students develop a time line using registrar tape and correlating marking off divisions of geologic eras. Above this they develop a Navajo time line of creation. Each week they focusing on the topic (era/period) of ...

Crater Counting Lab exercise
Kevin Mullins, Coconino County Community College
This lab is designed to teach students how we can estimate the age of other planetary surfaces by counting and size-binning impact craters. It also illustrates some examples of how erosional or deopositional ...

Teaching radioactive decay & radiometric dating: an analog activity based on fluid dynamics
Erika Grundstrom, Vanderbilt University
Radiometric dating/geochronology is a difficult concept for students. Using the (rather messy) medium of shampoo, students watch it flow through holes of different sizes, determine the exponential decay equation, ...

Time Scales of Climate Change
Erika Grundstrom, Vanderbilt University; Cara Thompson, Santa Monica College; maya elrick, University of New Mexico-Main Campus
This activity introduces students to the fact that climate change occurs at timescales of 1 year to 108 years and there are various drivers to explain these changes. It addresses how scientists detect these scales ...

Cyclostratigraphy and astrochronology exercise
maya elrick, University of New Mexico-Main Campus
Simple classroom activity to highlight how cyclostratigraphy and concepts of astronchronology can be used to refine age control in sedimentary rocks, estimate rates of processes, and for time control and ...
