Teaching about Earth's history is a challenge for all teachers. Time factors of millions and billions of years is difficult even for adults to comprehend. However, "relative" dating or time can be an easy concept for students to learn. Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards. Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata. Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.

Lesson: evolution: Date a Rock

The lab is one in which students get to work together to figure out some geologic "puzzles". Correlating rock layers involves using techniques like index fossil correlation, superposition, and horizontal originality to piece together what happened in the past. Students are tasked with three "mini-labs" in this class block, which are of increasing complexity. We read the information collectively, with particular emphasis on the definition of what constitutes an index fossil , and the criteria that make it one 1. I then briefly explain the multi-part nature of the lab note Procedure s A , B , and C below, which are done in order and then have students transition quickly into their lab groups.

Index Fossils & Correlation Lab

Date a Rock! SYNOPSIS Students get simulated "rock samples" which show a "highly magnified" selection of 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, students can figure the number of half-lives since the sample solidified, and therefore the "age" of the sample. This lesson would probably fit best whenever the ages of fossils or rocks have been encountered, enabling students to readily understand the essentials for how they are dated. Although it could just be a stand-alone lesson, it was intended to introduce our Deep Time lesson, laying the background for doing the isotope sequencing activity 15 in that lesson, then the Deep Time packet and worksheet which can be finished as a homework assignment.

There are two types of age determinations. Geologists in the late 18th and early 19th century studied rock layers and the fossils in them to determine relative age. William Smith was one of the most important scientists from this time who helped to develop knowledge of the succession of different fossils by studying their distribution through the sequence of sedimentary rocks in southern England.
