The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.

Teaching about Earth's history is a challenge for all teachers.

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.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.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.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.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.The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence.Locally, physical characteristics of rocks can be compared and correlated.



Fossils have been used to date rocks as they are time markers – many species lived at a particular time and later became extinct. As you saw from 1 above, the deepest rocks are usually the oldest, therefore the fossils found at the base of a rock sequence that has not been disturbed will be the oldest.

However, "relative" dating or time can be an easy concept for students to learn. In this activity, students begin a sequencing activity with familiar items — letters written on cards. 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.… continue reading »

A Relative Dating Activity is a hands on exercise which introduces students to the concepts of sequencing and using fossils to establish relative dates for rock strata. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. In the second part of the.… continue reading »

During the introductory activity, students learn that geology is a lot like detective work. Geologists infer the sequence and timing of events by collecting evidence and making observations, just like a detective. Students first make observations of a murder mystery. Then, they try to use simple principles to develop a story that is.… continue reading »
