Relative Dating

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.

Description

Comments about Including the Science and Engineering Practice In this activity, students are tasked with constructing a timeline using fossils. In order to align this activity more closely to this practice, teachers should require students to explain and justify each step of their timeline. For example, students should discuss which fossils are making their first appearance in a particular segment and which fossils have disappeared.

TCSS Earth Systems Unit 3 - Earth History Information Georgia Performance Standards: SES4. Students will understand how rock relationships and fossils are used to reconstruct the Earth's past. a. Describe and apply principles of relative age (superposition, original horizontality, cross-cutting relations. NOTE: This disclaimer is modeled after a couple of my favorite websites: The Science Spot and Middle School Science. Thanks, teachers! Relative Aging Study Guide Email me for a Relative Dating Teaching Idea which includes much of what is discussed here! One of the most basic concepts in teaching geologic History is distinguishing between. SW Science 10 Unit 6 Relative Dating Worksheet Name: Student #: Geologic Time Relative Dating The Law of Superposition In any undisturbed sequence of strata, the oldest layer is at the bottom of the sequence, and the youngest layer is .

In addition, students should discuss which, if any, of the fossils in a particular segment could be utilized as an index fossil. Once these answers are shared and evaluated, students would be prepared for a discussion of the Law of Superposition. This resource is explicitly designed to build towards this disciplinary core idea.

Comments about Including the Disciplinary Core Idea In this activity, students construct their fossil timeline simply by identifying overlapping fossils in the pieces; it is only after students construct their records that teachers are instructed to provide Figure 2-B which illustrates a hypothetical section of rocks with fossils. To bring this activity more in line with the Disciplinary Core Idea, teachers may wish to redesign the materials provided the students by cutting up FIgure 2-B and instructing students to organize these pieces instead.

the cruellest

Because Figure 2-B shows the fossils already embedded in rock strata, the relationship between fossils and rock strata is strengthened. Note: teachers may wish to assign a different code to the various fossil pieces. This resource appears to be designed to build towards this crosscutting concept, though the resource developer has not explicitly stated so.

one born every

Only one sequence is correct for each activity, but the answer is easily achievable if students can recognize the relationships detailed in the cards. The major difficulty that students may encounter is the concept that extinction is forever.

Once a species disappears, it cannot make a comeback at a later date or, in this case, card. Again, this exercise is only hypothetical but the experience provided to students can be transferred to actual rock data. The activity helps students to understand that long spans of geologic time can be broken down into more manageable segments by using relative ages.

If you make up seven boxes for seven lab groups, you'll need seven dollars in pennies. This is such a common standardized test subject, so it's worth covering well.

Once you've taught all the basics, a timeline exercise is a nice change of pace. Usually takes one or two class periods. We assign either the Missouri timeline or Earth timeline to various pairs of students. The Earth timeline is 5 meters long and a bit more difficult.

The Missouri is two meters. I usually don't do more than a couple of the five meter timelines per class. We have the students make the timelines and then answer the Timeline Comparison Questions. It might be worth the trouble for you to make up one similar to my Missouri version for your own state's geologic history.

Relative Aging Worksheets. You'll want to teach how to sequence rock layers during this unit.

Fossils and Geologic Time In this unit, we will learn about how fossil evidence show that Earth's surface, environment and climate have changed over time. Students will also measure the relative ages of rock layers and identify gaps in the rock record. Who's on First? 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.

You can make your own or surf the Web for other images you could use. Earth Science textbooks usually contain exercises covering this topic also. All mine are copyrighted worksheets so none are included here.

I can determine the relative age of rock layers based on index fossils, superposition, and cross cutting relationships. Nanofossils are the primary method of dating marine sediments. Trilobites were common during the Paleozoic Era ( to mya); about half of the Paleozoic fossils are trilobites. They evolved at the beginning of the.
