ASTR 101: General AstronomySections 0101-0110, Fall 2017
Course Description:Welcome to Astronomy 101! You are about to embark on an ambitious project - to survey our known Universe in one shortsemester. We hope that you'll find this course enjoyable and walk away with a better knowledge and understanding of theuniverse that we live in. With that goal in mind, the course attempts to focus on major concepts in astronomy and wherepossible tie those concepts into issues relevant to your life. For example, global warming, an important worldwide issue forthe 21st century, is also central to understanding the differences between the environments of Venus, Mars, and Earth. At amore philosophical level, understanding how our universe works and how planets, stars, and galaxies are formed gives us abetter perspective on our place in the universe and how special planet Earth is to our continued survival. Most of you havechosen this course to fulfill your science requirement (see GENED Requirements below). GENED courses are designed toensure that you will take a look at several different academic disciplines and the way they create and analyze knowledgeabout the world. We will introduce you to ideas and issues that are central to a major intellectual discipline and involve youactively 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 veryimportant! The material on the homeworks and exams are based upon the material covered in the lectures, the text, anddiscussion sections. If you have to miss a lecture or section, be sure to look at another student's notes and make sure thatyou understand what was covered. See me or your teaching assistant if you have questions. There will be times during thesemester, in both lectures and sections, when we may ask for written responses to questions. Your written answers willcount 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 readingassignment. A more careful reading is recommended after lecture. You should study your class notes some time before thenext lecture to make sure that everything is clear. I encourage you to ask questions in class, in discussion, in lab, and duringoffice hours.
Study Habits: Study wisely and ask for help if you need it. If you just cram the night before the exam, you probably willnot do very well. It is better (and easier) if you keep up with the material on a daily basis. If you have questions, please seeme or one of the TAs. We are here to help you learn.
Class Textbook: The Cosmic Perspective Fundamentals (2nd Edition), by Bennett,Donahue, Schneider, Voit, 2016 (ISBN-13: 978-0-13-388956-7). You do not need a CD orany online access for this class - just the hardcopy textbook. You may buy a used version ifyou wish. We will be covering most, but not necessarily all, of the material in the book.There will be reading assignments associated with the lectures. You are responsible formaterials covered in the lecture, discussion, and labs.
Class Lab books: Experiments in Astronomy (Fifth Edition), by Leo Blizand Michael F. A'Hearn, Voit, 2017 (ISBN-13: 978-1-323-58146-9) andASTR 101 Supplemental Lab Manual (Fall 2016 Edition), by the Universityof Maryland Copy Services, 2016 (ISBN-13: 281-8-440-15787-5). Youshould get the new fifth edition of the first book. An unused copy of thefourth edition is also OK if you get a good deal. But be sure that the book is100% intact, as you will have to tear pages out to hand in. You may not usephotocopies of the book for your labs.
Class Web Page: http://www.astro.umd.edu/~veilleux/ASTR101/fall17/ will have course information, lecture slides andhomework assignments, supplementary readings, and interactive programs to make ASTR 101 fun and to help you learn.See cool space pictures and movies!
ELMS: We will also use ELMS in this course. Your grades on assignments and exams, and point total throughout thesemester will be available on ELMS.
Class Meetings:Lectures meet in PHYS 1412 on TuTh from 11:00 am to 12:15 pm. Lectures are led by the professor and will includeseveral demonstrations, slides, videos, etc. There will be in-lecture activites that are graded.
Discussions Sections meet in ATL 2400 or ATL 1113 at times listed below, starting the week of September 5. Discussionsections are led by Teaching Assistants (TAs). The sections provide a smaller and more informal environment for furtherdeveloping the material taught in class. The TAs will also answer questions about the lectures and reading and will holdreview sessions before exams.
Labs meet in room ATL 0254 at times listed below starting the week of September 5. The labs are led by TeachingAssistants (TAs). You are required to attend lab section in order to do the labs; you MAY NOT start writing answers to thelab outside of the lab room. You must go to the lab time associated with your section number each week. If you expect tomiss your lab section due to illness or a University approved excuse, you should contact your TA as soon as you know andmake arrangements to attend another section in the same week if at all possible.
GENED RequirementsASTR 101 is intended for non-science majors and requires no more than a modest, high-school level science and mathbackground. This course satisfies the University of Maryland's requirement for a lab natural science course. To satisfy therequirement for a non-lab natural science course, you might wish to consider ASTR 100. Note that you cannot get creditfor both ASTR 100 and ASTR 101. Please be sure that you have chosen the correct course.
Discussion Sections and LabsYour weekly 50-minute discussion section, which begins the week of September 5, is an integral part of this course. Thesections 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 toenhance your understanding of the course material. Your TAs are an excellent resource; get to know them and use thatresource! Homeworks, exams, and other work will be returned to you during your discussion section. Please attend all yourdiscussion sections. The general schedule of the discussion sections can be found here.
Understanding laboratory techniques and reaching conclusions based on careful observations is a hallmark of scientificinquiry. Your weekly 2-hour lab is an important part of this course that provides you with the opportunity to think like ascientist. Our goal is that you leave ASTR 101 at the end of the semester with critical thinking skills that will allow you tobetter appreciate science in the news and elsewhere that you encounter it. The lab schedule can be found here.
Be sure to attend the discussion section and lab combination for which you registered. The only way to switch sections isthrough the registrar's office; unofficial changes are not allowed. Memorize your section number and put it on everythingthat you turn in.
Grading:Your grade is accumulated on a point scale throughout the semester with assignment totals summarized in the table below:5 homeworks at 10 points each; 12 discussion activities at 5 points each; 10 questions during the lectures at 4 points each;and 11 lab activities at 15 points each. A description of each of these components is detailed later in this syllabus. Youshould note that there are a total of 155 points in homework and lecture/discussion activities, and 165 points in labactivities. It is impossible to get a passing grade in this course by just showing up for the exams!
ASSIGNMENT Syllabus Cover Homeworks Discussions Lectures Labs Midterm I Midterm II Final Total
POINTS 5 50 60 40 165 100 100 200 720
Letter grades will be assigned based upon your curved cumulative score. Grades for some sections may be adjusted slightlyso that the average grade given by each TA is similar. Here is how your grade will be determined from your point total inthe class.
Letter Grade Course Total Percentage
A 630-720 87.5%-100%
B 540-629 75%-87.4%
C 450-539 62.5%-75%
D 360-449 50%-62.5%
F 0-359 0%-49.9%
The use of an absolute point scale makes it possible for everyone in the class to do well; it is up to you to put in the effort. Iwill use +/- modifiers on letter grades for the course; you will get a "+" if you are in roughly the upper 1/3 of point range ina letter grade and a "-" if you are in the lower 1/3. You can monitor your current percentage estimate of your grade in
ELMS as the semester progresses. If you are unsure about why something was marked wrong or you believe that it wasincorrectly marked wrong, please contact your TA promptly. Grading can be reconsidered for only a reasonable time afterthe assignment is returned to you, typically 7-10 days. We make every effort to grade your work correctly and to recordyour grades correctly into ELMS. We can make mistakes despite our best efforts. The last day for notifying us ofsuspected errors in previously recorded grades is Thursday November 30.
HomeworksThere are a total of five homeworks in this course. All homeworks are included with this syllabus and can also be obtainedfrom the Assignments link from the class website. They will NOT be posted on ELMS. Your answers must be writtenneatly or typed on a separate page from the questions; there will be a deduction of 2 points for answers squished into thespace between the questions or written on the back. It is perfectly ok for you to copy the questions over to your answerpage and then use as much space as needed to write the answer. Solution sets to the homeworks will be handed out by theTAs in the discussion sections.
Homeworks will be collected at the beginning of the lecture in which they are due. Fifteen minutes after the start of thelecture, any homework not turned in will be considered late and two points will be deducted from the total. Homeworksmay not be turned in by email. If you experience a valid emergency, you must write me and your TA an email before theassignment is due, telling us why you will be late.
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 websites, or allowing a friend to copy your homeworkis academic dishonesty (see Academic Integrity below) and will not be tolerated in this class. Moreover, it isremarkably easy to spot this form of cheating, so expect to be caught if you try it. The penalty is quite severe (again,see Academic Integrity). If you consult a reference other than the course text, please acknowledge it in yourhomework - this includes websites!
Midterm ExamsThere will be two in-class one-hour examinations which will be held in PHYS 1412 on the dates noted in the lectureschedule. These exams are closed book with no notes, calculators, cell phones, ipods, or implants allowed. Each exam willconsist of multiple choice questions, essay questions, and problem solving questions.
The schedule of lectures included in this syllabus shows what material will be covered on each exam. Please bring a penciland your ID card to each exam (including the final). If, for whatever reason, the University is officially closed on the examdate, the exam date shifts to the next lecture date. If official closures (e.g., due to snow) before an exam affect the materialcovered, either the affected material will be omitted, or the exam date may be altered, as deemed appropriate.
Final ExamAs per University rules, the final exam for this course will be held on Wednesday, December 13 from 8:00 am to 10:00am in PHYS 1412. This final exam is cumulative, that is, it will cover all material discussed in this course. However, sincethe material which comes after the second midterm will not have been covered by the midterm exams (see LectureSchedule), the weight on these units will be higher than on earlier units. The final will include multiple choice, essay andproblem solving questions, greatly resembling a longer version of the midterms. This exam is also closed book with nonotes, no computers, no calculators allowed. Please bring a pencil and your ID card to the final.
Missed Single Lectures, Discussion Sections or LabsWe will follow University policy: we will accept as an excused absence a self-signed note from a student who has missed asingle lecture or discussion section that is not an exam day or a day when homework is due, attesting to the date of theillness. The note must also contain an acknowledgement by the student that the information is true and correct and that
providing false information is prohibited under the Code of Student Conduct. The student is also obligated to make areasonable attempt to inform us of his/her illness in advance. Per university policy, students may only provide one self-signed medical excuse per semester. For multiple medically necessitated absences we will require documented evidencein the form of a doctor's note. For the policies on exams and homeworks, see below.
Missed ExamsThe first rule of missing exams is:
DON'T DO IT!
If you are not able to take an exam due to illness or other legitimate reasons (as outlined in the Academic Info section ofthe schedule of classes) and you wish to take a make-up exam, you must
1. contact me (by e-mail) before you miss the regularly-scheduled exam and2. submit a valid written excuse for your absence within one week after the regularly-scheduled exam.
Make-up exams must be taken promptly. In the case of the final exam, you must arrange for a make-up final within 48hours after the scheduled exam, and preferably much sooner as final grades must be submitted shortly after the date of thefinal.
Open HouseThe astronomy department hosts an open house on the 5th and 20th of each month at the university observatory which islocated just off campus on Metzerott Road. The open house includes a speaker talking about some aspect of astronomy.Following this short talk, there is public viewing of the heavens with the observatory's telescopes (weather permitting).This is your best opportunity to look through a real telescope. It's fun, so I highly encourage you to do it!
Extra CreditThe following are the only ways to earn extra credit in this class:
Do the Extra Credit questions on each homework assignment.Your TAs may give some extra credit in their discussion sections.
Because there will be points of extra credit available throughout the semester, there will not be any extra assignments /papers if, e.g., you miss a homework.
Electronic ResourcesThe World Wide Web is a very useful resource that we will make use of in this class. All students should obtain a computeraccount, which will include email and internet access. If you do not already have one, get a WAM account (this can bedone in ATL 1400, one floor down from your section class room). The webpage for this course is
It contains links to course information (including the contents of this syllabus), supplementary readings, and interactiveprograms to make ASTR 101 fun and to help you learn. In addition, this site is also a gateway to many other astronomylinks, including sites with up-to-date astronomical images that are made available to the public from telescopes in spaceand on the ground.
Course EvaluationIt is very important to get your feedback about the course. This allows us to improve the course for future students.Moreover, if you supply evaluations, it grants you access to the evaluations provided by other students - a very useful
resource in planning your future schedule. An announcement will be made in class when courses are open for evaluationlate in the semester.
Special CircumstancesStudents with a documented disability should let me know as soon as possible (preferably on the first day of class) so thatappropriate academic accommodations can be made.
Academic IntegrityThe academic community at the University abides by a Code of Academic Integrity, and this section uses parts of thatcode. 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, a book, or websites, allowing yourhomework or paper to be copied, and submitting forged excuses for absences from exams are violations of this code. If wesuspect that an incident of academic dishonesty has occurred, we will typically turn the case over to the Student HonorCouncil to investigate and resolve. If the suspected party is judged `responsible' for the act(s) of academic dishonesty, thenormal sanction is a course grade of `XF' which denotes failure due to academic dishonesty. This grade is far worse than anF and is recorded onto the student's academic transcript. The Code of Academic Integrity can be found in the AcademicInfo section of the Schedule of Classes and is printed in full in the Undergraduate Catalog; see this site if you have anyquestions about academic integrity or what is construed as academic dishonesty. We are very serious about this.
The basic principle is simple: everything you submit should be in your own words. Note that changing just a smallnumber of words in a sentence is not sufficient; we want your thoughts, not those of others.
* A surprising number of people do not seem to know what plagiarism is. A common example is cutting & pasting materialfrom the internet into your homework. It is wrong to submit the work of others as if it were your own.
Safe Learning EnvironmentThe campus is meant to be a safe place to learn, free from harassment and intimidation of any kind. If you haveexperienced any form of harassment as a member of the university community, you should contact the Office of CivilRights & Sexual Misconduct on campus. See the university policies and procedures onhttps://www.ocrsm.umd.edu/policies-and-procedures/index.html/ for more information. Please be aware that faculty(professors and TAs) are required by university policy to report any instance of misconduct observed or brought to theirattention. For confidential assistance with a harassment matter, contact CARE (see http://www.health.umd.edu/care).
