Title:
It's All Absolutely Relative: Creating a Geologic Time Scale
Description:
Students will begin this lesson by ordering the events of their morning using relative and absolute dating techniques. Students will also write a personal definition of the terms absolute age and relative age. Next, students will work with collaborative groups to order events in Earth's geologic history by relative age, then order those same events by absolute age in a scaled model timeline. Lastly, students will use the time-scale model created with their group members to analyze events in Earth's geologic history. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
