Watch a quick video of the students working through both card activities. Students will then answer questions related to the video and record their answers on their lab station sheet. Here are a couple of good sequencing games. Save yourself a ton of time and grab it now.

## Relative and absolute dating

Summary This lesson introduces *absolute* dating and a few ways in which scientists accomplish it. **Students will read about relative and absolute dating, as well as superposition.** Begin the lesson with discussing the difference between relative and absolute dating. These are what scientists consider when dating rocks.

Click here for the first game and click here for the second game. Which era best represents when humans first appeared on Earth? Public Information Logo and Guidelines.

Contacts E-mail More Distance Education. Students should have some prior knowledge of rocks and how they are dated. Students will understand how scientists use half-lives to date the age of rocks. Make sure they put them in chronological order. Run off on colored paper and cut out.

- Briefly, describe the geologic time scale.
- This student-centered station lab is set up so students can begin to explore geologic time scale.
- Do not copy and paste lessons onto your website.

You can do it with the class or prepare it prior to class. Each of the stations is differentiated to challenge students using a different learning style. You'd probably better cover simple calculations of half-life. They have to put the sketches in order and put a sticky label with each sketch explaining what cause the change in each sketch. Demonstrate Understanding of Science Concepts and Principles a.

Do not claim these lessons as your own work. Once you've taught all the basics, a timeline exercise is a nice change of pace. What is the difference between relative dating and absolute dating? You can make your own or surf the Web for other images you could use. We use teacher-made Fossil Identification Booklets but I don't have a pdf version of them.

## Learning Goals

Throughout the presentation, there are several opportunities for the students to Think-Pair-Share answers to the embedded questions. In this activity, students gain a better understanding of radioactive dating and half-lives. 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. It was easy to get caught up in the nomenclature, even though the things they describe should be familiar. Student Activity Now have the students make a timeline of their lives.

The following post will walk you through each of the steps and activities from the geologic time scale lesson plan. What is the law of crosscutting? This quick assessment allows me to verify student understanding of the concept of superposition. Students will be able to explain what a half-life of a rock is.

Good way to review the main geological and biological characteristics of the Eras. Once all groups finish, top 10 hookup each group records their info on the class decay table on the board and we calculate the averages of the class. This is a worksheet from Glencoe that also covers this topic. What is the law of inclusion?

Basic understanding of how radiometric dating works is useful. The geologic time scale lesson includes a PowerPoint with activities scattered throughout to keep the students engaged. 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. Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs.

We usually just give students the finished product and many students have trouble with seeing how the finished diagram came to be. Tell students they will be learning about the geological timescale of the age of the Earth and how scientists determined it. Students will be instructed to complete a few tasks and record answers on their lab sheets.

## RELATIVE VS. ABSOLUTE DATING by Terasa Hodson on Prezi

Have the entire class stand up in the center of the room, all huddled together. Students who can answer open-ended questions about the lab truly understand the concepts that are being taught. The assess it station is where students will go to prove mastery over the concepts they learned in the lab. At this station, students will be watching a short video explaining the laws of relative rock dating.

All mine are copyrighted worksheets so none are included here. This Glencoe site has great stuff. Students will be examining a number models of different layers of the earth.

The Missouri is two meters. Introduction to Change Over Time. By having several predetermined stopping points, I am able to give students time to interact with all these new concepts, and turn the presentation into a more interactive learning experience. The Teaching Geologic History Packet is now available. Operations Center Staff Directory.

- This activity would also be easy to adapt when talking about half-lives within a chemistry course.
- You can be creative with what they are sampling, but this label helps with misconceptions, such as that fossil fish have their own half lives, and not the carbon in them.
- Click here for a Timeline Scoring Guide.
- Summary In this activity, students gain a better understanding of radioactive dating and half-lives.
- No words or sound effects this time!
- The idea of radioactive dating can be broken down into a relatively simple concept of half-lives that the students should be able to grasp.

Cut off feet of receipt tape. Relative Age of Rocks Add to Favorites teachers like this lesson. The full lesson is available for download from my TpT store.

Students will have a more in-depth understanding of what radioactive decay is. Research has shown that homework needs to be meaningful and applicable to real-world activities in order to be effective. 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.
