Textbook: "Astronomy Today" (Sixth Edition), Vol. 1: The solar System by Eric Chaisson and Steve McMillan

Also Needed: a CPS Clicker

Student Companion Workbook: " Online Journey Through Astronomy: The Solar System"
by Michael Guidry, Margaret Riedinger and Frank Edward Barnes (Student Companion) [Available at UTK Libraries website through electronic "Course Reserves"(type "astronomy" after clicking on button for "Course Reserves")]

Tests:   There will be both daily quizzes and period long exams this semester.
The 5 minute daily quizzes will be one or two short questions on the lecture material to be covered that day. Your reading and note preparation should make these easy for you to answer. They will be handed out at the start of each lecture. If you are late you will miss them and they will not be made up.

The four period long exams will be mostly objective questions (T-F, multiple choice, matching, fill-ins) with some essay questions for extra credit. The lowest of the four grades will be dropped. THERE ARE NO MAKEUPS. Only extreme medical or family emergencies (with written proof) are reasons for any type of extra-normal arrangements. Do not plan vacations, long weekends, or other personal absences without checking the Daily Syllabus and talking with me first to be sure that you will not be missing an exam or an especially important lecture.

Grading: The breakdown will go like this for your base grade:

Daily Quizzes
  15 pts.

Participation
(class discussions and/or WEB) 

  10 pts.

Period Quizzes (drop the lowest)

  75 pts.

Total (Base grade)

100 pts.


Extra credit items add to the base grade calculated above. One point is given for each well written video or article report. Two different supervised trips [roof (solar, night), planetarium, eclipses, meteors, etc.] plus their typed reports add five points total. Mentored research papers can add up to a full letter grade depending on the quality and work effort. 

The grading scale is the usual one of A ³90, B+ ³85, B ³80, C+ ³75, C ³70, D ³60, and F <60. FX is for those who stopped attending or never attended (Among first year students that is an unfortunate but common occurrence.). NOTE: UTK has now added  minus grades as well.

Attendance is taken daily using a clicker (available from the bookstore). Seats are assigned to speed up taking attendance as well as to try to get to know your names. This way I am aware of who is participating via their attentiveness, questions and involvement in discussions during class. If you are unable to come to class please let me know why. You can either tell me in advance before or after class, during office visits or by email. This enables me to record that good reason why you are absent on my attendance chart.

A Cautionary Note: Please put your cellphones on vibrate or turn them off before entering the lecture hall. Although your ringtones may be interesting and costly to you the rest of us don’t need to be interrupted by them. 

Extra Credit: Day telescope observation sessions are available from the roof of the Physics building (conducted by Mr. Paul Lewis). 
Mr. Lewis will talk to you and show you features of the solar atmosphere such as sunspots, prominences, plages, etc.  You can prepare for thess sessions by browsing the chapter in your book on the Sun as well as the study guide for the Sun. You meet on the roof of the Physics building. [through the door at the very top of the East stairwell (near the elevator doors)].


Mr. Lewis' office is on the first floor of the Nielsen Physics next to the elevator doors and his phone number/answering machine is at 974-9601.
If it is raining, snowing, or overcast then there will be no viewings. If you are in doubt that your session will be cancelled due to weather call or email Mr. Lewis to check. Not showing up without a valid reason can get you barred from future sessions since you will have wasted a time slot that another student could have used.

It is also very important that you try to do your observing as early as possible since bad weather usually causes many cancellations of the extra credit sessions. This causes many students to miss their chances for extra credit. Don't let it be you! One solar session wil be considered for extra credit. A stamped form from Mr. Lewis PLUSone page typed essay description of your observing trip should be handed in to me for you to get full credit.

We also arrange special trips to the Heritage Planetarium in Maryville for shows relevant to our course material. These will be announced well in advance in class and on the newsgroup.

You can also watch astronomy videotapes in the Astronomy Reading Room on the mezzanine floor of the Physics building at any time that you have available and the room is open (usually 8 a. m. - 11 p. m.). You will need to see me before or after class in my office to obtain course relevant video tapes to watch.
two page typed report on what you have watched should be submitted to me for grading. The subject of a video must relate to the material covered during this semester, e.g., planets, moons, comets, asteroids, the search for life in the universe. (NOT material on stars, supernovae, black holes galaxies, etc. – those are the subject matter for the Astronomy 162 course.)

You may also (with advance permission from me) do a research paper relating to material covered this semester but in much greater depth. The topic will usually be something that relates to your major or personal interests. You will be expected to meet with me about once a week to discuss your topic, references, outlines and drafts as you pursue your topic. A minimum of 10 outside references (articles in journals and books) are required and the paper must be 15 typed pages of text. This is a lot of work but an excellent paper will add a full letter grade to your final evaluation and bring you much personal satisfaction in learning about how astronomy and your interests coincide.
