AP Activity One Explain to your students they will be participating in an activity to determine a rock formation's relative age. Divide your class up into five small groups.
Assign each of the groups one of the five principles from the just viewed video. Group One, you are going to be Team Original Horizontality. Group Two, you are going to be Team Superposition. Group Three, you are going to be Team Inclusions. Group Four, you are going to be Team Unconformities. Next have the groups meet and discuss their principle.
Most importantly, have them draw a visual representation of the principle on a large sheet of poster board. They can also utilize the Internet to gather any more information. Let the groups each nominate a spokesperson to give a presentation of their findings to the class. Lastly, display all five images at the front of the class. Present various factoids of information about each principle and challenge the students to see if they can match up the data with the correct picture.
Do you have any more questions or comments about this activity? Instructions continued Lesson Two Start the video and pause for the first time at 0: Can you date a fossil with a rock? Can you date a rock with a fossil?
For what do scientists use the Geologic Time Scale? Now restart the video and pause this time at 2: Who was William Smith? Where did he live? What is the principle of fossil succession?
Was Smith the first to understand this concept? Next restart the video and pause this time at 3: What is an index fossil? Why isn't a horseshoe crab a good index fossil? What are some good index fossils? Restart the video, playing until the end. How did Smith solve the problem of two outcrops from two periods? Can this process even date findings from different continents?
Recap the entire video lesson and answer any pertinent questions. Have your students take the lesson quiz. Activity Two Inform your students they are going to draw a picture of an index fossil. Make available to students the colored markers, colored pencils and different sized poster board. According to the second video lesson, three of the favorite index fossils utilized by scientists are trilobites, ammonites, and scallop shells.
You can choose to draw one, two or even all three of these. Display images of the three types of fossils at the front of the class. If desired, allow students access to the Internet to view more images of these three fossils. Finally, have your students share their drawings with the entire class. Extension Three common types of rocks are igneous, metamorphic, and sedimentary. Write a three-page paper comparing and contrasting these three types of rocks.
