Explain why “D” in the rock layer represented by DM is the same age as “M” Explain why “D” in the rock layer represented by OXD is older than the “D” in DM. Name the index fossils on the list

9. Copyright © 2007 Stevens Institute of Technology Center for Innovation in Engineering and Science Education TWO UWZ GU FG CFN CD XMC AM Name the index fossils Name one of the youngest index fossils How did you decide on the correct sequencing of the fossil C? Which one, C, is the oldest and in what layer can you find it? If I find a fossil G in North America, in what layer do you think I can (possible locations) find G in Asia? If a scientist in Russia finds a fossil X in the third layer of rocks from the top (youngest), will you believe him? Explain. If the scientist insist that he/she truly found X in the third layer of the younger rocks, what should happen to support his claim?

10. Copyright © 2007 Stevens Institute of Technology Center for Innovation in Engineering and Science Education Revise your model Draw and explain how you think scientists sequence events to determine the age of the layers of rock using fossils? How is your revised model different from your initial model?

11. Copyright © 2007 Stevens Institute of Technology Center for Innovation in Engineering and Science Education Sequencing Activity using pictorial models Answer the questions on 4 –5 points for the first correct sequence & answers –3 points for the second –1 point for the third

12. Copyright © 2007 Stevens Institute of Technology Center for Innovation in Engineering and Science Education Which fossil organisms could possibly be used as index fossils? Name three organisms represented that could not be used as index fossils and explain why.

Name the index fossils. Based on this activity, how do scientists work with other scientists to create a sequence of events?

15. Copyright © 2007 Stevens Institute of Technology Center for Innovation in Engineering and Science Education Revise Your Model In the box below draw and/or write the different fossils that you know. Draw and explain how you think scientists sequence events to determine the age of the layers of rock using fossils? What is different with your model before and after? What did you add, delete, or change?
