Building a Local Stratigraphic Column: A research-based assignment for an introductory course
This activity has been reviewed by 2 review processes
HideSummary
Students build a stratigraphic column for a pre-selected area through the compilation of a series of individual research projects. Students are required to conduct introductory field research as well as a literature search to become "experts" on a selected stratigraphic unit. In addition to a final report, students will present their information at an outcrop on an end-of-semester field trip.

Description and Teaching Materials
This teaching module consists of a series of three activities. The first introduces the geology of the area, the second requires student research, and the third allows for the dissemination of each student's research findings.
Activity 1: Map Exploration and Stratigraphic Unit Assignment
The purpose of this activity is to introduce the students to the local geology. It works well as an assignment in a 50 minute lecture setting at the beginning of the semester. Using a geologic map, have the students explore the area using a prepared set of questions. The instructor will follow this with a discussion of the geologic history, alluding to processes and events that will be discussed in lecture during the semester, such as tectonic events and cratonic sequences. Finally, the students will choose the stratigraphic unit on which they wish to become "experts". Worksheet questions will vary with location. A sample worksheet is included below.
Activity 2: Stratigraphic Unit Research
Once each student has chosen their stratigraphic unit, the instructor will give them a handout discussing the written requirement. The student is responsible for finding a local outcrop from a pre-selected list and collecting samples for research. The final report should be a compilation of original data collection and interpretation with a literature review. Report styles can be tailored to individual preferences. A sample is included below.
Activity 3: Field Trip Presentations
A field trip is scheduled for the last lab period for students to present the results of their research. Organize the field trip stops in stratigraphic order so that the class "builds" the stratigraphic section. A summary discussion after the field trip can help tie in the concepts and tectonic processes from lecture into the local setting.

Teaching Notes and Tips
This activity can be scaled up or down depending on class size and availability of accessible outcrop by assigning larger units such as formations or smaller units such as members.
This exercise can also be tied into a Sedimentology course. Using the same unit they were assigned in Historical Geology, the students can produce thin sections of their collected rock samples and complete a sedimentological analysis of the unit. This reinforces the work they completed previously and allows the students to build on their previous interpretations.

Assessment
Assessment of the research paper and presentation is completed using a rubric. A sample rubric can be found at http://www.k-state.edu/assessment/toolkit/measurement/resrubric.pdf.
