PURPOSE OF LABORATORY
Lab is intended to let you work through various examples of astronomical projects that astronomers really have done. In these labs, we will emphasize how astronomers use observational data in order to study the universe. Many times there is no one "correct" answer, just as there is no unique answer in frontier research. The emphasis is on your judgment, how you think through the procedures to obtain a "reasonable" interpretation of your observations.
Key themes which will recur throughout many of the labs are the following: a) How far away are things and how big are they? b) How and why do we classify things? c) How do we find mathematical relationships between physical quantities and how reliably can we predict things from the relationships we find? The key point is not to learn miscellaneous astronomical facts but to get used to thinking logically about a set of observations, some of which may not be very accurate. The exercises start close to home and gradually work their way through the Solar System to the edge of the universe. We hope to show how each step outward builds on the previous ones.
LAB MANUAL
1. Buy a copy of the lab manual "Experiments in Astronomy" by Leo Blitz and Michael
A'Hearn, 1991 edition.
2. All reports must be handed in on the pages from the manual. If you lose your lab
manual, you must buy another!
3. There is a packet of photographs in your lab manual. Put your name and section
number on the packet and GIVE IT TO YOUR TA.
LAB REPORTS
1. We encourage you to read the lab before coming to class.
2. Do not write anything in your lab book before coming to lab. All written work
required for the lab must be done in class.
3. Most weeks you will work with a partner to take data. Except for these data, your
report must be your own work, not a transcription of your partner's. You are expected to do your own calculations and answer questions in your own words.
4. Be sure your work is legible—if we can't read it, we can't grade it.
5. All lab reports must be turned in, by you in person, to your TA at the end of your lab
period. The only exception to this rule is Lab #1.
GRADING
1. Each lab counts 12 points except Lab 1 counts 10 points and Lab 2, Celestial Sphere,
which takes two weeks, and counts 24 points.
2. Today’s MILKYWAY subscription is worth 5 pts. and must be completed by Feb. 17.
See your TA or Mrs. Deming if you have problems—do not miss the deadline.
3. Your numerical grade for lab and discussion is calculated by your TA by summing
your points.
4. Astronomy 101 exams will contain questions concerning the labs. The lab topics are
closely connected to the lecture topics and should help you understand the concepts.
MISSED LABS
1. If you miss your lab, contact your TA before your next lab.
—send your TA email (BEST)
—phone your TA and leave a message
2. The university recognizes only three excuses for missing class:
religious holidays, university-approved travel, or illness.
3. We will also accept these excuses, but only for 1 lab:
car trouble or death in the family
additional problems: TA will listen and make a decision whether or not you may
makeup the lab.
4. If your excuse has been approved by your TA, he will write it down and you will be
entitled to a makeup lab (Apr. 22-25, or May 14—see p. 6 of BIG syllabus)
5. Unexcused absences for a Lab result in a grade of zero.
6. Missed discussion activities may be excused, but only if you contact your TA within a
week.
ACADEMIC HONESTY AND YOUR LAB EXPERIENCE
We stress that your calculations and answers must be your own even if you worked with a lab partner to get the data. Many students are unclear how to draw the line between individual learning and/or useful and permitted collaboration. We also know that a few students may find it very tempting to violate the Honor Code intentionally.
We quote from the Code of Academic Integrity distributed by the Student Honor Council:
"A. CHEATING: Intentionally using or attempting to use unauthorized materials, information, or study aids in any academic exercise.
B. FABRICATION: Intentional and unauthorized falsification or invention of any information or citation in an academic exercise.
C. FACILITATING ACADEMIC DISHONESTY: Intentionally or knowingly helping or attempting to help another to violate any provision of this Code.
D. PLAGIARISM: Intentionally or knowingly representing the words or ideas of another as one's own in any academic exercise."
Suspected cases of academic dishonesty will be referred to the Student Honor Council for review. If you are found to have violated the Code of Academic Integrity, you are likely to receive an XF grade for the class rather than just a zero on the lab.
In the specific context of this course, academic dishonesty includes copying another person's lab report, fabricating lab data, and utilizing lab reports from past years. Although we encourage you to read the labs before class, all work on lab reports must be done in class. It is not allowed to arrive at the beginning of class with a completed lab, to arrive at class with the answers on another piece of paper and transcribe to your lab manual, to use completed lab reports from past years as "reference" sheets, or to turn in a lab report which was not completed entirely by you in class.
In the labs where you are working with a partner gathering data, it is expected that both partners have an understanding of the lab, and that the parts of the lab beyond data gathering (specifically the calculations and questions) will be done independently. Your lab report should always be in your own words, never a verbatim copy of your lab partner's report. In labs where you are supposed to work individually, consultation between normal lab partners should be limited to questions of how to make measurements and how to do calculations. You should not copy any part of another student's report or consult with another student to arrive at answers to questions.
If you have any questions or are uncertain about anything in this syllabus, ask your TA or Mrs. Deming for clarification.
