Thirteen Ways to Tell Time Backwards
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.
