Fossil dating activity

By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. Relative dating tells scientists if a rock layer is "older" or "younger" than another.

This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.

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.

However, "relative" dating or time can be an easy concept for students to learn.

Materials: two sets of sequence cards in random order (set A: nonsense syllables; set B: sketches of fossils), pencil, paper Procedure Set A: 1) Spread the cards with the nonsense syllables on the table and determine the correct sequence of the eight cards by comparing letters that are common to individual cards and, therefore, overlap.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.These major concepts are part of the Denver Earth Science Project's "Paleontology and Dinosaurs" module written for students in grades 7-10.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.

On a larger scale, even between continents, fossil evidence can help in correlating rock layers.
