What is the law of crosscutting? Students will understand how scientists use half-lives to date the age of rocks. Students will be instructed to complete a few tasks and record answers on their lab sheets.

Throughout the presentation, there are several opportunities for the students to Think-Pair-Share answers to the embedded questions. Once you've taught all the basics, a timeline exercise is a nice change of pace. Basic understanding of how radiometric dating works is useful. Run off on colored paper and cut out.

## Compare and contrast relative and absolute dating

Click here for a Timeline Scoring Guide. You can make your own or surf the Web for other images you could use. You'd probably better cover simple calculations of half-life. Relative Age of Rocks Add to Favorites teachers like this lesson.

If you make up seven boxes for seven lab groups, you'll need seven dollars in pennies. Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives. Briefly, uniform dating australia describe the geologic time scale. The following post will walk you through each of the steps and activities from the geologic time scale lesson plan.

Good way to review the main geological and biological characteristics of the Eras. In our class the students had just enough time to do one sample, but depending on your time frame you may have students switch samples to do more than one. Students will have a more in-depth understanding of what radioactive decay is. Students will record their observations on their lab sheet.

Relative Aging Worksheets. The Teaching Geologic History Packet is now available. One of the most basic concepts in teaching geologic History is distinguishing between Relative and Absolute Time. Each of the stations is differentiated to challenge students using a different learning style. Here are a couple of good sequencing games.

## Relative and absolute dating

This lesson introduces *absolute* dating and a few ways in which scientists accomplish it. **Click here for Absolute Time Fact Sheet.** What is the difference between relative dating and absolute dating? Summary In this activity, students gain a better understanding of radioactive dating and half-lives. During the explanation piece, the teacher will be clearing up any misconceptions about geologic time scale with an interactive PowerPoint, anchor charts, and interactive notebook activities.

Usually takes one or two class periods. This Glencoe site has great stuff. All mine are copyrighted worksheets so none are included here. Students graph, post questions, and data table will be looked at. This activity would also be easy to adapt when talking about half-lives within a chemistry course.

## Powerpoints

Don't see the need for quiet seatwork when we could be doing something more lasting, like a game or lab or powerpoint or other more active activity. Once you get through the concepts of radiometric dating, there are a few practice problems in the powerpoint you should go through as a class. If you can think of a way to separate the concept of radioactive decay from the terminology to begin with, you may see better results. In my class, terminology was the most difficult part i.

Once all groups finish, each group records their info on the class decay table on the board and we calculate the averages of the class. New information needed to be introduced with parent and daughter isotopes. Once this info is calculated, dating site php template students create a graph comparing the class average of parent isotopes to the number of half-lives.
