GEOLOGY 22: LAB INFORMATION
There will be four labs during the semester, with 4 sections available for each (dates and
times specified on the syllabus). The general purpose of the labs is to provide
opportunities for smaller groups to engage in more active and hands-on learning about some
important geological tools and materials.
The first lab deals with basic mineral and rock
classification and identification. There will be many other opportunities to practice
mineral and rock identification in the succeeding labs and field trips.
The second lab deals with topographic maps - how to
"read" the information they contain about the shape of the land's surface, the
likely rock types and structures underlying the surface, and the processess which have
shaped the present landforms.
The third lab involves exercises designed to help one
better understand and visualize plate motions and plate boundaries using both globes and
The fourth lab is an introduction to interpreting geologic maps, which provides good
practice in 3D visualization of the geological units and structures that we have been
studying in class and have seen on the field trips.
Toward the end of the semester, there will be a completely optional "lab"
(nothing to be turned in and graded!), for however many people want to come, at which
Karen and Jan will discuss the nature of basic research in the geological sciences, using
as examples their own research. There will probably be just two sections for this
"lab"; times will be announced later.
Lab times and attendance
There are four lab sections from which to choose. Once you have chosen a section, you are
obliged to stay in that section. Attendance will be taken. If you have a conflict,
please meet with us in advance and we will try to accommodate you in a different section
for that one time. Makeup labs are inconvenient for all involved and are not likely to be
as complete a learning experience as the regularly scheduled sections. All labs will be
held in MacMillan Hall 101.
We encourage you to work together on lab assignments, and hope that you will be able to
learn from one another. This does not mean that it is acceptable to copy another person's
lab or homework (and we will know). All answers should reflect an individual understanding
of the material.
Homework is due as specified in the syllabus. Labs are due at the end of each lab period.
Handing in and Returning
Homework assignments are to be handed in at the beginning of the class period on the day
they are due. Labs are to be handed in at the end of each lab session. Late assignments
should be handed in directly to Jan, Karen, or one of the TA's. Corrected homework and
labs will be returned at the end of class (in MacMillan Hall 115). Any that are not picked
up will be kept by the TA's and will available from them. We will do our best to return
the graded assignments within a week after they are due.
Grading and Lateness
Homework and lab assignments that are handed in late will be penalized 10% of the score
per late day (ouch!). We can be accommodating if there are special circumstances, but we
must be notified in advance of reasons why you cannot make the deadline.
Despite our diligent efforts to be fair and consistent with grading, some mistakes are
inevitable. If you think that something has been graded incorrectly, please come see us
during our office hours. Please do not quibble over a point or two. This will generally
have a negligible impact on your overall grade at the end of the semester.
Neatness and Legibility
Please write legibly, or print if necessary. We are geologists, not translators. If we are
having a problem reading someoneís writing, we will let you know and will expect that it
be resolved by the next assignment. If you force us to guess at what is written, you may
be disappointed with our conclusions.
Professors or TAs will be available in Geo/Chem 029 each day to answer any questions you
might have about the course, or about other matters. We encourage you to stop by and get
acquainted, and ask questions about textbook or lecture material, or work there with other
students on homework questions with the guidance of a TA or professor. The times are: Mon
3-4, Tues 7-8, Weds 2-3, Thurs 2:30-3:30, Fri 2-3. In addition, you can reach any of us
easily by email, and make an individual appointment if you like. In general you should
direct questions about the text and lecture to Jan or Karen, questions about the labs to
one of the TAs, and questions about the homeworks to anyone of us.
S/NC & Course
Students taking the S/NC option for this course may wish to have a written evaluation of
their progress, called a Course Performance Report (CPR). Jan or Karen would be
happy to fill these out, but you should make your request for a CPR by mid-semester.
