Ocean Stratigraphy Challenge

This material is replicated on a number of sites as part of the SERC Pedagogic Service Project

Summary

This is a complex puzzle beginning with a description of a stratigraphic section from a deep-sea core. The students are asked to explain the sequence of rock and sediment types and to devise an experiment to test this hypothesis. It is intended for students with some prior knowledge of oceanography, sedimentary geology, and plate tectonics and requires them to synthesize all of this knowledge to answer the question.

Learning Goals

This question enables students to:

Context for Use

This is a piece of someone's exam, but could be the basis of an in-class puzzle. It involves a combination of concepts, as do many real-world problems and might work very well at the end of an intro course (perhaps as a practice for the final exam).

Teaching Materials

All you need are:

Teaching Notes and Tips

Print the question as a handout and give it to small groups or pairs of students to work on for 15-20 minutes. The next 30+ minutes can be spent going over the solution and discussing concepts behind it.

Assessment

This exercise was originally one of three questions on a 75-minute exam and with the helpful rubric could easily become part of another exam.
