This site provides all information, instructions, downloadable materials, and links to online materials for an exercise developed for use in a Geology of the National Parks course. Using the provided maps, groups of 3 to 6 students are asked to identify between 8 and 12 geologic provinces based on topography, the age of rocks, and the rock types. As a result of this exercise, students will become ... Full description.

This lesson shows students that age-dating rocks involves counting atoms and comparing the counts. Students use simulated rock samples, which show a highly magnified selection of 128 atoms, each sample with a different proportion of the atoms of two different elements: a parent radioisotope, and its daughter product. By counting the parent radioactive atoms and knowing the half-life of those atoms, ... Full description.

This activity has students compare the magnitude of geologic time with spans of time in a person's lifetime, which is often difficult for many students. They use a long paper strip and a reasonable scale to represent visually all of geologic time, including significant events in the development of life on earth as well as recent human events. This activity provides students with an opportunity to ... Full description.

In this lab activity using M&M candy, students will explore the concepts of radioactive decay and dating. Students generate a radioactive decay table to simplify the math, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in Wright Valley, Antarctica. In a follow-up exercise, students will solve a mysterious Arctic ... Full description.

In this lesson, students will learn that geological time can be measured in several different ways, providing independent lines of evidence for measuring deep time and sequencing geological and biological events of the past. Students explore different methods of measuring geological time, comparing the time dimensions, mechanisms, and materials used for each. Full description.
