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.

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

For questions Principles) 1 through 5, indicate which principle(s) of relative dating guided you in arriving at your answers. pauihon 1.
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. In reading earth history, these layers would be "read" from bottom to top or oldest to most recent.
If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. By using this information from rock formations in various parts of the world and correlating the studies, scientists have been able to establish the geologic time scale.
This relative time scale divides the vast amount of earth history into various sections based on geological events sea encroachments, mountain-building, and depositional eventsand notable biological events appearance, relative abundance, or extinction of certain life forms.
Objectives: When you complete this activity, you will be able to: 1 sequence information using items which overlap specific sets; 2 relate sequencing to the Law of Superposition; and 3 show how fossils can be used to give relative dates to rock layers. Materials: two sets of sequence cards in random order set A : nonsense syllables; set B : sketches of fossilspencil, 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.
The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence.

If the letters "T" and "C" represent fossils in the oldest rock layer, they are the oldest fossils, or the first fossils formed in the past for this sequence of rock layers. Now, look for a card that has either a "T" or "C" written on it.
Since this card has a common letter with the first card, it must go on top of the "TC" card. The fossils represented by the letters on this card are "younger" than the "T" or "C" fossils on the "TC" card which represents fossils in the oldest rock layer.
Sequence the remaining cards by using the same process. When you finish, you should have a vertical stack of cards with the top card representing the youngest fossils of this rock sequence and the "TC" card at the bottom of the stack representing the oldest fossils.
Interpretation Questions: 1 After you have arranged the cards in order, write your sequence of letters using each letter only once on a separate piece of paper. Starting with the top card, the letters should be in order from youngest to oldest. Which of the following is the oldest?

Relative dating is the process in which a scientists determines if a rock layers or fossils are younger or older than other rock layers or fossils. Relative dating uses a few different principles. Principle of Superposition: The rock layers on the bottom were deposited first, therefore they are the oldest.
