Day 137: Geologic Timeline Lab – Day 1 April 4, 2007

Posted by Admin in Geology, Homework.

Constructing a Geologic Timeline that represents the full history of the Earth with any measure of detail is a daunting task.  But we undertook this task with enthusiasm (right?) in class today.  The first step was to determine the scale we’d use.  Given a 5-meter long strip of cash register tape, students determined the best scale to use was to set 1 meter to equal 1 billion years.  From there, students worked with their lab partner to calculate the distances on the timeline represented by various Eons, Eras, Periods, and Epochs.  Tomorrow we’ll begin placing these values onto the physical timeline.

All conversion calculations should be complete on pages 2 and 3 of the lab when students return to class tomorrow.
