Other Required Materials:

Scientific Calculator- you must bring this to every lab session. (An adequate scientific calculator need not have any graphing or programming capabilities, but should have basic arithmetic and trigonometric [e.g., sin, cos, tan] functions. This type of calculator costs as little as $10.)

Ruler with English & metric units- you must bring this to every lab session.

Pencil-you must bring this to every lab session (not a bad idea for lecture either!).

Lab exercises: most of these will be group efforts since we don’t have13 sets of all of the needed tools! However, all students are required to hand in their own, individual lab reports (with the names of their lab group members) for each.

Quizzes will occur every few weeks and cover the salient points of the most recent lectures. Don’t forget to bring a calculator!

Attendance is required, and will be assessed through the timely completion of lab exercises, in-class activities, and quizzes. Late and unexcused make-up work may be accepted, but with a 10% penalty per class session unless prior arrangements have been made.

Research Project

Each student will select, propose, conduct, and report a research project over the course of the semester making use of the available lab equipment. This can be something related to their own research or using samples provided by the professor (or another professor).

Students must arrange a meeting with the Professor during the 3rdweek of classes to discuss possible research topics and writing skills. A one-paragraph topic statement, plus a list of at least 5 relevant sources, is due on February 18.

The research proposal will be in the format of a Geological Society of America student research grant proposal (~5-6 pages). The proposal presentation will be 5 minutes for undergraduate students ant 10 minutes for grad students.

For the peer review component, each student will review proposal or paper drafts from at least two other students.

The final paper will be in the format of a manuscript submitted to the journal Geology (~8 pages). For undergraduate students, the final presentation will be 10 minutes long. For graduate students, the final presentation will be 15 minutes long.

Broad course goals and objectives

This course is designed such that students will:

• Understand how and why chemical and mineralogical information can be obtained using various X-ray analytical methods.

• Design, propose, conduct, and report an individual analytical research project.

• Gain hands-on experience with both sample preparation and XRD and XRF instrumental methods.

• Judge the quality of geochemical data by calculating errors and counting statistics.

By the end of this course, it is the instructor’s hope that all students will be able to conduct independent, unsupervised analytical research using UWM’s X-ray labs and equipment.

Course outcomes

This course addresses the development of advanced skills in each of the following:

• Critical reading, logical thinking, and the use of argument and evidence (research proposal, research paper).

• The use of appropriate stylistic and disciplinary conventions in writing and speaking (research proposal, research paper, and research presentations).

• Critical analysis of information from primary or secondary sources for some portion of the speaking and writing (research proposal, research paper).

Learning Accommodations

I believe it is both important and appropriate to make accommodations that facilitate and improve the learning environment for all students. If you will need accommodations in order to meet any of the requirements of this course, please contact me as soon as possible. We may want to consult the Student Accessibility Center (229-6287; to help assist in devising an appropriate solution.

Accommodations for Religious Observance

Accommodations will be made if you need to miss class and/or a required assignment for a religious observance. Please inform me in advance so that appropriate arrangements can be made.

Teaching Policies

As a student in this course you are responsible to abide by the Department of Geosciences teaching policies and all University established policies. Scholastic dishonesty of any type will not be tolerated. Scholastic dishonesty, a breach of the standards of academic integrity, includes, but is not limited to, cheating, plagiarism, and any act designed to give unfair academic advantage to the student. In this course, the work you hand in for credit must be entirely your own work, except when group work is specifically permitted. Even if you work with others, you are expected to hand in individual assignments written in your own words. You are welcome to discuss any course related problems or issues with me. My goal, and that of the department, is to create a productive learning environment for all students.

More information on University policies regarding course syllabi is available at

Class participation is an important part of the course. You are expected to come prepared to class and to take an active role in class discussions and projects.

Credit-hour policy: This course is designed so that students will spend about 3 hours a week (45 hours total) in class or doing supervised lab activities, about 2 hours a week on course readings and studying (30 hours total), about 2 hours a week on homework (30 hours total), and an average of 3 hours a week on the research project (less time early in the class, more later: 45 hour total). This totals 150 hours, or 50 hours/ credit hour.
