Campus Observatory: you will need to visit the campus observatory twice during the semester; it will be open from 9-10 pm two days each week (specific days to be announced). See attached Observatory information/objects pages; more details will be given in lab.

Teaching Assistants: Maria Patterson, mtpatter@nmsu.edu, Astronomy Room 108, phone 646-6328, office hours TBD and by appointment; M.J. Clark, thegeek@nmsu.edu, Astronomy Room 209, phone 646-7734, office hours TBD and by appointment. Both TAs have mailboxes in Astronomy Room 101.

Textbook/supplementary materials: We will be using an online book (Universe, by Freedman and Kauffman) and database of tutorials and problems (AstroPortal) during this class. You are required to purchase access to this database; online homework will make up 20% of your class grade! A discounted rate is available if you purchase an access card at the NMSU bookstore. Once you have this access card, go to http://courses.bfwpub.com/universe8e.php to access the online material. Instructions on using the online textbook and database will be given in class/lab.

Reading material in the online textbook will be identified that is supplementary to what we cover in class. Note, however, that the lecture material defines the class, not the book material. Class notes are available on the class web site.

Lab text: AY 110G Lab Manual, available at Kinko's for about $15.50. This is required. You must buy the Fall 2008 version.

Grades will be based on:

Homework 20%
Lab reports 30%
Midterm 1 12.5%
Midterm 2 12.5%
Paper 5%
Final 20%

There may also be a small amount of extra credit available in the labs, which the TAs will discuss. Most likely, a minimum grade of 50-60% will be required to barely pass the class.

Attendance policy: Attendance at every lecture is highly recommended. This is especially true since we will not be following a specific textbook. Attendance will be taken at each lecture using a signup sheet, and this will be used, in part, to judge interest on the part of each student. The attendance record will be consulted to determine grades for borderline cases. When you come to class, you are expected to be polite with respect to other, e.g., no cell phones or talking in class. Sitting in the back row will only be allowed if all other seats are occupied.

GENERAL INFORMATION AND REQUIREMENTS

Class / general education goals

This class satisfies the New Mexico general education requirement for a laboratory science. This requirement is designed to help students become competent in the following five areas:

The class is designed to attempt to educate in these areas through examples in astronomy. Of course, we also hope that students come away from the class with increased interest and knowledge in general astronomy!

Many of the core competencies are addressed through the laboratory section, so students are urged to spend some time and effort thinking about the labs and handing in assignments that reflect this thought.

Class outline

The class is split up into four main sections, as listed below. Some of the questions we will address in each section are also given:

  1. Introduction and Overview of the Universe. Why is astronomy interesting and relevant? What is the difference between astronomy and astrology? What are all of the different objects in the Universe, and roughly how far away are they? How do astronomers look back in time? How do astronomical objects move through space? What is the size, shape, and age of the universe?
  2. Motions in the sky: astronomy by eye. How do the Sun and stars appear to move through the sky, and why? Why do we have seasons? How does the Moon appear to move through the sky, and why does the moon have phases? What is an eclipse? How do planets appear to move through the sky, and why? How do we know that the Earth and planets revolve around the Sun? What were the historical steps that led to this knowledge?
  3. The physical basis of astronomy: gravity and light. Why do objects in the Solar System move as they do? How does gravity work? How can we use our understanding of orbits to measure masses of objects in the Universe? What are the masses of different object? What is dark matter and why do we think it is there? What is light, how is it produced, and what can it tell us about the objects that produce it? Why do we use telescopes and how do they work?
  4. The nature of astronomical objects. What is the Solar System and what are the objects that compose it? In what respect are planets similar and different to each other? What are the processes that affect the appearance of planets? How hot is it on the planets, and why? What is the greenhouse effect? How old is the Solar System? What do we know about planets around other stars? How do stars produce light? In what respects are stars similar and different to each other? What are stars made of? How do stars evolve? How old are they?

ASTRONOMY 110G - Sections M04,M05,M06 - Fall 2008 - Approximate class schedule

The assignments, except for midterms, refer to assignments in AstroPortal. Note that these will be due Wednesday midnight (except for the first assignment). The assignments include both reading suggestions and a set of homework problems. The lowest two homework grades will be dropped, so if you have a particularly busy week, you can afford to miss a couple of assignments, although, of course, the more you take, the better your top grades will be. When you do the online assignments, take advantage of the online feedback so that you go away from the problems understanding more, whether you got them correct or not.

ASTRONOMY 110G - Sections M04,M05,M06 - Fall 2008 - Lab Syllabus

Lab Description

Lab is comprised of weekly indoor labs and two visits to the campus observatory. The lab sections are taught and run by the TAs; if you have questions about labs or lab policies, consult with them first, but the professor has ultimate responsibility for both class and labs, so feel free to come to him/her if you have any unresolved issues.

Indoor Labs

EXERCISE (65 points): This section is completed in groups. You will work in groups of 3-5 people in the lab to answer questions from lab materials. It is important that the write-up are done neatly; illegible handwriting cannot (and will not) be graded.

SUMMARY: (35 points): This section is to be completed at home on an individual basis. Summaries are to be typed or well-written in black or blue ink. They should be between around 1 page typed (double spaced) or 1-2 pages hand written (double spaced).

Write-ups for both exercise and summary will be due at the beginning of the next lab meeting. Those submitted after that will be considered late.

Campus Observatory

You must take two sets of observations at the campus observatory during the semester: one during the first half (before October 15) and one during the second half. There will be a TA present (not necessarily one of the TAs for our particular class section) during times given below. If you go early in the observing peroid, you will likely be able to get done quicker, as there are usually less people present. Also, remember, the weather is unpredictable, so saving thing for the last few nights in the period can be dangerous!

We would like you to go to the observatory and look at several objects that the TA is showing. You should then hand in a written description of the object (color, shape, etc.) to your lab TA; we would like you to look up one fact about each object and write it down along with your object description.

Late Submission

There will be a 10 percent penalty for each day after the due date. No points will be given after a week. If you have a valid excuse (medical reasons, etc.), talk to your TA, but you have to show proof of your claim. Late submission can be handed to your TA in person or dropped in their mailbox.

Participation

As mentioned in the ASTR 110G Lab Syllabus, you are expected to attend all the lab meetings. Attendance will be taken. Note that the TWO lowest indoor lab scores will be dropped. NO observatory notebook scores will be dropped.

Grades

Labs are worth 100 points each. Each campus observatory report is also worth 100 points. Lab scores comprise 30% of your total grade in this course.

Miscellaneous

You are expected to read the lab manual before each lab meeting; the labs will make much more sense if you spend a bit of time getting acquainted with them beforehand. Arrive on time. Please turn off cell phones, as they are a huge distraction; if they become a problem your lab instructor may take further action.

Lab Philosophy

The labs are used as tools to aid in the understanding of the concepts explored in the lecture. These concepts are expanded upon by applying them in a practical manner in the classroom and at the campus observatory.

Requirements

You are expected to fulfill the following four general requirements:

  1. ATTEND ALL LAB MEETINGS: There will be NO make up labs. If you know ahead of time that you will miss lab, you can possibly make arrangements with your lab instructor to attend a different lab section that week. Since emergencies and illness do occur, your two lowest lab grades will be dropped.
  2. COMPLETE LAB PROJECTS: All in-class labs are due the next time your lab meets, usually the next week. Keep in mind that each of these labs is worth 100 points which includes a summary at the end that is worth 35 points. Don't forget the campus observatory visits!
  3. PREPARE FOR LAB: To be adequately prepared, you need to read over the lab before coming to class. Your lab instructor may decide to give pop quizzes at the beginning of lab to ensure that the reading is being done.
  4. PARTICIPATE: You are encouraged to ask questions at any point during the lab about anything that is related to the material being covered. Remember, you are in the class to learn about astronomy, not to just finish the labs (or so we like to think). Participating in class is not only a good way to help you learn, but it also helps others in the class.

If you stick to these guidelines, you should do fairly well in the class. If you are lacking in any of these four areas, there are two extra credit labs in the back of your lab manual that you may do, but ask before you do them. If you have questions about an upcoming lab or about one that you have completed, be sure to stop by during office hours.

ASTRONOMY 110G - Sections M04,M05,M06 - Fall 2008 - Campus Observatory Information

Location:

The campus observatory is located on Williams Street south of Steward Street, just to the south of the parking lots and in front of (west side of) the track. It is set back from the street somewhat. Look for three dome-shaped buildings.

Requirements:

You are required to observe four objects during each half-semester to fulfill your outdoor requirement for the ASTR 110G lab.

Due Dates:

Your observatory notebooks will be due in lab during the week of:

Hours:

Final observatory hours are still TBD (we have to negotiate with intramurals to find times when the field lights can be off) and will be posted in class. However, it is likely that the campus observatory will be open two days a week from 9:00-10:00. The first week of observatory will be the first week in September, and the last week will be the last week of November. The observatory will not be open during Thanksgiving Break.

Weather:

Since we have optical telescopes at the campus observatory, we cannot see through clouds or rain. Therefore, if you look up in the sky and cannot see any stars, chances are the telescopes cannot see any either. In such cases, the observatory will be closed for the night. If you are unsure whether the observatory is open or not, you can either check the ASTR 110G homepage through a link at http://astronomy.nmsu.edu/astro/observatory or call the observatory recording at 646-6278. Both of these will be updated about an hour before observatory begins, and again if the observatory closes part way through the night. If you find that either of these has not been updated on time, please inform your lab instructor the next time you see him/her.






NOTE: you cannot make up any missed observations. Come to the observatory early in the month to make sure you get your observations. Unless the observatory is closed due to weather for more than 6 nights in a given month, there will be NO makeup dates!!
