Course Description: In this seminar-style course, students will learn about meteorites and the stories they tell us about the birth and evolution of the solar system. Learning will be accomplished primarily through class discussions and readings of recent scientific articles. Topics will include meteorite classification, asteroids, chondritic and differentiated meteorites, the solar nebula, extinct radionuclide chronology, the processes and consequences of heating asteroidal bodies, pre-solar grains, abiotic synthesis of organic matter, impact and collisional processes, and martian meteorites.
Text: A Coursepack for G410/510 (Meteorites)
will be available through Clean Copy, and additional reading material will
be placed on Electronic Reserve at Millar Library. Both are required.
Class readings: An essential component of this class will involve reading and thinking about the materials placed in the coursepack and on electronic reserve. These readings have been selected to provide a relatively comprehensive and timely survey of meteorite-related topics. They will form the basis for class discussions, homework assignments, and exams (see below). Unlike most text materials for classes, these readings rely on peer-reviewed published articles, written by scientists for others. The instructor will help students to understand and critically analyze the articles. A copy of the reading list will be provided on the class website.
Exams: There will be one mid-term exam and a Final. These exams will be some combination of short answer and multiple choice. No make-up exams will be given except for a medical emergency or unless arrangements to take the test at another time are made with the instructor in advance. The Final (held on Dec. 9, 8:00-9:50) will be comprehensive. Questions from the mid-term exam may be re-used on the Final. Exams may be curved. Answers and score distributions for the exams will be posted on the class website.
Homework: Homework assignments will be built around the class readings. They will be due the day that the associated class readings are due. They will NOT be accepted late. However, they can be submitted to the instructor in one of several ways: as hardcopy in class or in the instructor's mailbox in the Geology Department, or electronically by e-mail sent to the instructor, provided that the answers are part of the main body of the message (I will not open attachments because of the virus danger these pose.) A check system will be used to grade homework. Here is how the check system will work: 0 points = not turned in or turned in late; check = 2 points = homework turned in on time and satisfactory; check-plus = 3 points = homework turned in on time and exemplary; check-minus = 1 point = homework turned in on time but less than satisfactory. Information about the homework assignments will be posted on the class website.
Class attendance and class participation: To encourage participation in class discussions, students will be graded partly on attendance, and partly on their additional participation in class activities. Neither of these can be "made up". Class attendance will be determined purely by the number of class meetings attended by a student, whereas class participation will be determined by the contribution that a student makes to discussions in class.
Grades: Grading is done on a straight scale although
curves will be used at my discretion. Grades will be assigned based on
scores as follows: 95% or above = A, 90-94.99% = A-, 87-89.99% = B+, 83-86.99%
= B, 80-82.99% = B-, 77-79.99% = C+, 73-76.99% = C, 70-72.99% = C-, 67-69.99%
= D+, 63-66.99% = D, 60-62.99% = D-, less than 60% = F. I generally do
not give "I" grades. This class can be taken Pass/No Pass. If you elect
to change your grading option, please inform me in writing. Letter grades
will correspond to the standards given in the PSU course catalog.
