University of Georgia - Department of Geology
The final exam has been graded, course scores have been calculated, and letter grades have been reported to the registrar. There is a page showing the grade distribution, as well as that of previous years' classes.
Exam II has been graded and will be or was handed back on Tuesday, October 16, at the end of class. A histogram of the grades is shown below.
The class vote in favor of having Lecture 17 cover the Big Bang, and thus the origin of the Universe, means that the reading assignments for that lecture have changed. The new reading assignments are shown in the table below. The syllabus is no longer correct with regard to the readings for that lecture.
Exam I has been graded and will be or was handed back on Tuesday, September 18, at the end of class. A histogram of the grades is shown below.
Lecture 5 on Tuesday, August 28, went long enough that we did not get to the creation story for that day. We will cover it at the beginning of class on Thursday, August 30. That means we will do two stories on Thursday, August 30, CS4 at the beginning of the period and CS6 at the end of the period.
A link has been added to Lecture 4 for access to a diagram like on shown in class in Lecture 4.
The revised syllabus for this section of GEOL 1122 is now available as a PDF. The two revisions are (1) correction of the date of the final exam (December 6, not December 16) and (2) an updated geologic time scale for page 4. The time scale is also available as a stand-alone PDF.
Geology majors, and anyone else, may be interested to know that Railsback will give a talk on The Earth Scientist's Periodic Table of the Elements and Their Ions on Tuesday, August 14, at 3:30 pm in Room 200A GG. Railsback created a new and different periodic table for geologists and, more generally, Earth scientists, that was published in 2003 and since has gone on to repeated re-release and translation. He gives this ready-for-the-road fifty-minute talk each fall for new students. GEOL 1122 students are no way required to attend, but they are welcome to do so if they like.
Last year's distributions of grades on mid-term exams (a link lower in this pages leads to previous years' distributions):
Persons withdrawing before the midterm withdrawal deadline will be given WPs, not WFs.

*Notes regarding readings:
All readings are in Stanley's Earth System History (3rd edn), except for web pages, which are labeled "WWW", and for numbers labeled "CS", which are nunbers for stories in Creation Stories from around the World.
Pages in brackets are suggested reading that may make lecture material easier to understand.
Reading assignments do not include "Earth System Shift" ("ESS") inserts unless specifically noted.
Reading assignments include all figures to which reference is made, even if the figures fall outside the page range indicated.
