Laboratory Exercises
Attendance during the Lab period is mandatory to receive credit for the exercise. Exercises are due one week after the lab period. Make-ups are ONLY allowed by making advance arrangements through the Office of Studies. Late work will not be accepted.
Lab Exercises are subject to change without notice and may be updated the week of the lab exercise.
Problem Sets
Problem sets are due one week after being assigned. Make-ups are ONLY allowed by making advance arrangements through the Office of Studies. Late work will be penalized no less than 25%.
Extra Credit:
Extra Credit 1:
Every Friday at 3:30 pm in Room 301 Locy Hall, the Department
hosts a speaker who discusses current research.
The list of speakers, titles, and dates
is here. While
not all the speakers cover topics directly relating to this course, we offer 3 points
for a 2-page summary of each talk. This extra credit
is due two weeks after the talk.
Extra Credit 2: Book report
We offer students 23 extra credit points for reading and reporting on one of
two books:
1) Rare Earth: Why Complex Life is Uncommon in the Universe by Peter
Ward and Donald Brownlee
2) Pompeii by Robert Harris
Reviews should give your perspective of the book as both a book critic and a geologist.
The write-up should be at least five pages long.
It is due
the first day of finals week, but may be turned in at any time.
Extra Credit 3: Movie report
We offer 4 extra credit points for watching and reporting on one of
several movies shgowing Holywood's unusual ideas of geology:
Capricorn One, 10.5, Volcano, The Core, Dante's Peak, Supervolcano.
Reviews should give your perspective as both a movie critic and a geologist.
The write-up should be at least two pages long. It is due
the first day of finals week, but may be turned in at any time.
