AGE OF THE EARTH
Geologist Ralph Harvey and historian Mott Greene explain the principles of radiometric dating and its application in determining the age of Earth. As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate. Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4. Segment from A Science Odyssey: “Origins. View in: QuickTime RealPlayer.

Activity: Radioactive Dating
Scientists developed a way to categorize and explain earth’s history GEOLOGICAL TIME dating and I can create a conceptual model of the geologic time scale. Use timeline worksheet to make your timeline, include all the major parts on.
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. These major concepts are part of the Denver Earth Science Project’s “Paleontology and Dinosaurs” module written for students in grades Extinction of species is common; most of the species that have lived on the earth no longer exist.
The complete “Paleontology and Dinosaurs” module takes approximately four weeks to teach. The “Who’s On First?

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 key 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.
A Relative Dating Activity is a hands on exercise which introduces students to the contain are used to establish relative ages of major events in Earth’s history.
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 activity, students progress to dating rock layers by sequencing fossils found in the different strata. Using the results of these activities, teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils.
It should be noted that teachers may have to edit the introductory materials provided to students, since the readings may be too difficult for younger middle school students. Both parts of the activity can be completed in one class period. MS-ESS Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s 4.
Examples can include the formation of mountain chains and ocean basins, the evolution or extinction of particular living organisms, or significant volcanic eruptions. Assessment Boundary: Assessment does not include recalling the names of specific periods or epochs and events within them. This resource is explicitly designed to build towards this performance expectation.
Teachers should note that the stratigraphic information provided for the second part of the activity is purely hypothetical; however, this is still a valuable exercise since its successful completion will allow teachers to initiate a discussion on the Law of Superposition and index fossils without overwhelming students with too many details.
In particular, these activities allow students to explore the portion of the Clarification Statement dealing with the evolution or extinction of particular living organisms by pinpointing when specific fossils appear and disappear in the strata record. This resource is explicitly designed to build towards this science and engineering practice. Comments about Including the Science and Engineering Practice In this activity, students are tasked with constructing a timeline using fossils.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy layers of rock are called strata. Relative dating does not provide actual numerical dates for the rocks. Next time you find a cliff or road cutting with lots of rock strata, try working out the age order using some simple principles:. Fossils are important for working out the relative ages of sedimentary rocks.
Throughout the history of life, different organisms have appeared, flourished and become extinct. Many of these organisms have left their remains as fossils in sedimentary rocks. Geologists have studied the order in which fossils appeared and disappeared through time and rocks. This study is called biostratigraphy.

We often express time in hours or days, and 10 or 20 years certainly feels like a long time. Imagine if you needed to think about one million, million, or even several billion years. These exceptional lengths of time seem unbelievable, but they are exactly the spans of times that scientists use to describe the Earth. Have places like the Grand Canyon and the Mississippi River been around for all of those years, or were they formed more recently?
When did the giant Rocky Mountains form and when did dinosaurs walk the Earth? To answer these questions, you have to think about times that were millions or billions of years ago. For example, they have learned that the Mississippi River formed many millions of years after the Grand Canyon began forming. They have also concluded that dinosaurs lived on the Earth for about million years. You will also learn some of the clues that scientists use to learn about the past and shows you what the geologic time scale looks like.
Before you work through this lesson, think about the following questions. Be sure that you can answer each one. They will help you better understand this lesson. The first principle you need to understand about geologic time is that the laws of nature are always the same.
