ASTR100: Introduction to Astronomy
Sections 0201-0207, Fall 2000


Class Meetings:

Lectures meet in PHYS 1412 on MWF from 9:00am to 9:50am. Lectures are led by the professor and will include several demonstrations, slides, videos etc.

Discussion Sections meet in CSS 2400 at times listed below starting the first week of September. Discussion sections are led by Teaching Assistants (TAs). The sections provide a smaller and more informal environment for further developing the material taught in class. The TAs will also answer questions about the lectures and reading and will hold review sessions before exams.

Course Description:

Welcome to Astronomy 100! You are about to embark on an ambitious project - to survey our known Universe in one short semester. We hope that you'll find this course enjoyable and walk away with a better knowledge and understanding of the universe that we live in. With that goal in mind, the course attempts to focus on major concepts in astronomy and where possible tie those concepts into issues relevant to your life. For example, global warming, an important worldwide issue for the 21st century, is also central to understanding the differences between the environments of Venus, Mars, and Earth. At a more philosophical level, understanding how our universe works and how planets, stars, and galaxies are formed gives us a better perspective on our place in the universe and how special planet Earth is to our continued survival.

Most of you have chosen this course as part of your CORE Distributive Studies Program, the general education portion of your degree program (see Core Requirements below). CORE Distributive Studies courses are designed to ensure that you will take a look at several different academic disciplines and the way they create and analyze knowledge about the world. A faculty and student committee approved this CORE Distributive Studies course because it will introduce you to ideas and issues that are central to a major intellectual discipline and because it promises to involve you actively in the learning process. Please take advantage of the opportunities this course offers!

Course Expectations:

Attendance: In order to succeed in this course, I expect you to attend ALL lectures and discussion sections. This is very important! The material on the homeworks and exams are based upon the material covered in the lectures, the text, and discussion sections. If you have to miss a lecture or section, be sure to look at another student's notes and make sure that you understand what was covered. See me or the teaching assistant if you have questions. There will be times during the semester, in both lectures and sections, when you will be asked for written responses to questions. Your written answers will count towards your grade in the class.

Preparation: I expect you to be prepared to work. You will understand the lecture more easily if you preview the reading assignment. A more careful reading is recommended after lecture. You should study your class notes sometime before the next lecture to make sure that everything is clear. I encourage you to ask questions in class, in section, during office hours, or over email.

Study Habits: Study wisely and ask for help if you need it. If you just cram the night before the exam, you probably will not do very well. It is better (and easier) if you keep up with the material on a daily basis. If you have questions, please see me or one of the TAs. We are here to help you learn.

Grading:

I grade on a point scale with different assignments weighted as shown in the table. A description of each of these components is contained in this syllabus.

POINTS

Letter grades will be assigned based upon your curved cumulative score. Grades for some discussion sections may be adjusted slightly so that the average grade given by each TA is similar. Here is how your grade will be determined from your point total in the class.

Letter Grade
Course Total
Percentage
A
656-750
87.5%-100%
B
562-655
75%-87.5%
C
469-561
62.5%-75%
D
375-468
50%-62.5%
F
0-374
0%-50%

The point scale makes it possible for everyone in the class to do well. For example, if everyone scores above 75% in the course, you would all receive either an A or a B letter grade. I may adjust the number of points required to get a given grade depending on the class averages; however, any adjustment will make it easier to get a given grade, never more difficult. Students with a documented disability who wish to discuss academic accommodations should contact me as soon as possible.

Midterm Exams

There will be two in-class 50-minute examinations which will be held in PHYS 1412 on Friday, October 13 and Friday, November 10. These exams are closed book with no notes and no calculators allowed. Each exam will consist of 20 multiple choice questions and three or four essay or problem solving questions. These exams are incremental (i.e., non-cumulative) checkups on how well you have learned the material. The schedule of lectures included in this syllabus shows what material will be covered on each exam. Please bring a pencil and your ID card to each exam (including the final).

If for whatever reason, the University is officially closed on the exam date, the exam date shifts to the next lecture date.

Final Exam

According to University rules, the final exam for this course will be held on Friday, December 15 from 1:30 pm to 3:30 pm in PHYS 1412. This final exam is cumulative, that is, it will cover all material discussed in this course. However, since chapters 12 - 17 will not be covered by the midterm exams (see Lecture Schedule), the weight on these chapters will be higher than on earlier chapters. The final will include multiple choice, essay and problem solving questions with the exact combination to be determined.

This exam is also closed book with no notes and no calculators allowed. Please bring a pencil and your ID card to the final.

Missed Exams

If you are not able to take an exam due to illness or other legitimate reasons (as outlined in the Academic Info section of the schedule of classes) and you wish to take a make-up exam, you must
Make-up exams will be given within one week after you submit the valid written excuse. The format of the make-up exams may be different from that of the original exam (e.g., it may not have any multiple choice questions i.e., it may consist entirely of essays, problems, and short answer questions; it may also include ORAL questions).

If you miss the final exam and have a valid written excuse, you must arrange for a make-up final within 48 hours after the scheduled exam. The make-up final, like the make-up midterms, may not have any multiple choice questions.

Discussion Sections

Your weekly 50-minute discussion section, which begins the first week of September, is an integral part of this course. The sections are run by the TAs, with just general guidelines from me; they will generally include a review of lecture material, presentation of problems and material not covered in lecture, exercises and quizzes etc. These sections serve as a forum to enhance your understanding of the course material. Your TAs are an excellent resource; get to know them and use that resource! Homeworks, Exams, and other work will be returned to you during your discussion section. Please attend all your discussion sections. If for some reason you have to miss a section meeting, you may go to one of the other section meetings offered by your TA that week if you get permission from him/her first.

Be sure to attend the discussion section for which you registered. The only way to switch sections is through the registrar's office; unofficial changes are not allowed.

Homeworks

There are a total of eight homeworks in this course. All homeworks are included with this syllabus and can also be obtained from the Assignments link from the class website. Homework #1 is the syllabus cover sheet. Please type or writeup your assignments neatly. Solution sets will be distributed in sections.

All homeworks are due in class at 9:00 am (i.e., at the beginning of class). Homeworks turned in after 9:15 am will be considered late and docked at least 20%. After the end of class on the due date, no more homework will be accepted. If for some reason you cannot turn the homework in person, you should ask a friend to turn it in for you. If you experience a valid emergency, you must write your TA an email or leave your TA a voice mail message before the due date telling him/her why you will be late. In this case, you must secure a valid written excuse and arrange with your TA to have the homework turned in to him/her as soon as possible and, in any event, absolutely no later than the beginning of the next lecture.

If for whatever reason, the University is officially closed on the due date, the due date shifts to the next lecture date.

Although you may discuss the homework problems with your friends, the final writeup must be in your own words. Copying from a friend's homework, copying from a book, or allowing a friend to copy your homework is academic dishonesty (see Academic Integrity below) and will not be tolerated in this class. If you consult a reference other than the course text, please acknowledge it in your homework - this includes websites!

Open House

The astronomy department hosts an open house on the 5th and 20th of each month at the university observatory which is located just off campus on Metzerott Road. Each open house consists of a speaker talking about some aspect of astronomy. Following this short talk, there will be public viewing of the heavens with the observatory's telescopes (weather permitting). Dress warmly as you will be outside when using the telescopes! A list of scheduled speakers and topics, as well as information about a shuttle service that can take you to the observatory, is available online at http://www.astro.umd.edu/openhouse/.

Your open house assignment consists of three parts:

The paper must be typed, and should be between 2 and 3 pages long. Please proofread and check your spelling before you turn in the paper!

To avoid everyone rushing to the observatory at the last minute, we will adopt the following policy. There will be three due dates for this report. If you turn your paper in early, you will earn extra credit points in addition to the normal points for the assignment.

Due Date
Extra Credit Points

When you go to the observatory, you will be asked to write down your name, course, and section number so that we know when you went. Please note that in order to obtain extra credit, you must turn in your paper on either of the first two due dates. If you went to the observatory early in the semester but do not turn in your paper until the last due date, you will not receive extra credit. This is in part to encourage you to write the paper right after the open house experience when your memory of the event is still fresh in your mind.

Extra Credit

There will be no extra credit papers. The following are the only ways to earn extra credit in this class:

Class Web Page

The World Wide Web is a very useful resource that we will make use of in this class. All students should obtain a computer account, which will include email and internet access. Your TA can assist you with obtaining the account and learning to use it. The webpage for this course

will contain links to course information, supplementary readings, and interactive programs to make ASTR100 fun and to help you learn. In addition, this site is also a gateway to many other astronomy links, including sites with up-to-date astronomical images that are made available to the public from telescopes in space and on the ground.

Special Circumstances

Students with a documented disability should let me know as soon as possible (preferably on the first day of class) so that appropriate academic accommodations can be made.

Academic Integrity

The academic community at the University abides by a Code of Academic Integrity. Acts of academic dishonesty include cheating, fabrication, facilitating academic dishonesty, and plagiarism. Activities such as cheating on exams or quizzes, copying homework from a friend or book, allowing your homework or paper to be copied, and submitting forged excuses for absences from exams are violations of this code. If we suspect that an incident of academic dishonesty has occurred, we will turn the case over to the Student Honor Council to investigate and resolve. If the suspected party is judged `responsible' for the act(s) of academic dishonesty, the normal sanction is a course grade of `XF' which denotes failure due to academic dishonesty. This grade is recorded onto the student's academic transcript. The Code of Academic Integrity can be found in the Academic Info section of the Schedule of Classes. It is printed in full in the Undergraduate Catalog and on the web at http://www.inform.umd.edu/CampusInfo/Departments/JPO/code_acinteg.html. Please refer to this Code if you have further questions about what is construed as academic dishonesty. We are very serious about this.

Core Requirements

ASTR100 is intended for non-science majors and requires no more than a modest, high-school level science and math background. This course satisfies the CORE Distributive Studies requirement for a non-lab physical science course (CORE code PS). To satisfy the CORE Distributive Studies requirement for a lab physical science course (CORE code PL), this course must be taken simultaneously with ASTR 111 (Observational Astronomy Lab) or you must take ASTR101 (General Astronomy). Note that you cannot get credit for both ASTR100 and ASTR101. Please be sure that you have chosen the correct course.
