Students graph, post questions, how do i hook up and data table will be looked at. They have to put the sketches in order and put a sticky label with each sketch explaining what cause the change in each sketch. Have them add up important events with pictures. Click here for a Timeline Scoring Guide.
Click here for a lesson on how to teach your students to calculate half-life using a simple table. Throughout the presentation, there are several opportunities for the students to Think-Pair-Share answers to the embedded questions. These are in worksheet form. You'll want to teach how to sequence rock layers during this unit.
It might be worth the trouble for you to make up one similar to my Missouri version for your own state's geologic history. What is the law of crosscutting? 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. Do not claim these lessons as your own work.
Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives. Students will be examining a number models of different layers of the earth. They not only enjoyed this activity, dating title ideas but they really gained a better understanding of it as well. This Glencoe site has great stuff.
We use teacher-made Fossil Identification Booklets but I don't have a pdf version of them. Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives. Home Professional Learning.
Parent isotopes are represented by the M side up radioactive. Save yourself a ton of time and grab it now. You can do it with the class or prepare it prior to class. Which statement is incorrect about the Geologic Time Scale?
This quick assessment allows me to verify student understanding of the concept of superposition. Students will be instructed to complete a few tasks and record answers on their lab sheets. Once this is done, students have some post questions they are given that they should record in their science notebook.
This is a worksheet from Glencoe that also covers this topic. You can read more about how I set up the station labs here. The following post will walk you through each of the steps and activities from the geologic time scale lesson plan.

Once you've taught all the basics, a timeline exercise is a nice change of pace. You might want to show the film as a nice break from the usual routine. During each trial, students record the number of radioactive parent isotopes and record this in a data table. Relative Age of Rocks Add to Favorites teachers like this lesson. Briefly, describe the geologic time scale.

We have the students make the timelines and then answer the Timeline Comparison Questions. Good way to review the main geological and biological characteristics of the Eras. Earth Science textbooks usually contain exercises covering this topic also. Click here for the first game and click here for the second game.
Begin the lesson with discussing the difference between relative and absolute dating. Click here for Absolute Time Fact Sheet. You'll want to cover methods used by scientists to measure absolute 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. Basic understanding of how radiometric dating works is useful.
- This lesson introduces absolute dating and a few ways in which scientists accomplish it.
- In my class, we used people age as an example.
- This was a new activity we implemented last tear.
- Students will be able to infer the relative age of rocks and fossils from index fossils and the ordering of the rock layers.

Earth Science Absolute Dating A Measure of Time
The assess it station is where students will go to prove mastery over the concepts they learned in the lab. Have the other students guess which Era is being dramatized. Here is a good version of a half-life lab using pennies in shoe boxes. Contacts E-mail More Distance Education.

- Use mathematical reasoning to communicate information.
- Here are a couple of good sequencing games.
- What is the law of inclusion?
- Wonderful review of many of the concepts we've been covering in our Geology Unit.
Do not copy and paste lessons onto your website. Which era best represents when humans first appeared on Earth? Once all groups data is on the table, you can calculate the average for each run and determine a class average.
Demonstrate Understanding of Science Concepts and Principles a. Run off and cut out for the game. This student-centered station lab is set up so students can begin to explore geologic time scale. You can make your own or surf the Web for other images you could use.
Absolute dating (radiometric dating)
Powerpoint introduction is attached. 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. 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. Run off on colored paper and cut out. Draw pictures related to important events in your life in the correct place on the timeline.
