Contacts and Communications
A student’s success in any course depends critically on their level of engagement,
which requires clear and consistent communications with the relevant TAs and
Instructors.
The primary vehicle for communications in this course is the Course (Moodle) Website
to which a student should refer regularly. The course website will be updated
frequently and will contain all pertinent administrative and curricular information; e.g.,
assignment deadlines.
The first level of communications in this course outside of the lecture time is through
the Discussion Forum on the course website. A Discussion Forum allows students to
discuss course-related issues, primarily with other students, but also with TA(s)
assigned to the Forum.
The second level of communication is via email. Students who for whatever reason
prefer not to use the Discussion Forums can contact their TAs and instructor via the
Faculty of Science
2
email address: nat1740m@yorku.ca. It is strongly recommended you use your
“my.yorku.ca” account when sending email. Experience has shown that email to/from
an external email address may not always arrive successfully through no fault of the
sender. Email responses will normally be sent within 24-48 hours. Please note
though that if a question is course-content related (no personal content), it should be
posted to the Discussion Forum so both the question and its answer can be shared
with the class as a whole. Questions raised on email that already have been
answered on the Discussion Forum may not receive a response.
Regular Course Announcements from the course instructors will keep you informed on
important dates, administrative aspects of the course and the occasional media-
oriented story relevant to the course.
Students who require face-to-face meetings with the Instructor should make use of the
Instructors’ Office Hours or book a personal appointment via nat1740m@yorku.ca .
All members of the course students, TAs and instructors should adhere to
“common sense” NETiquette guidelines to communicate effectively and courteously
online, including:
The use of a reasonable ID; e.g., “D. Lee” and not “Joker47”
A specific and relevant subject line
The use of appropriate language, avoiding rudeness, vulgarity and sarcasm
Being concise
Expanded Course Description
Natural Science (NATS) courses are designed to provide an opportunity for non-science
students to gain familiarity with the nature of science, its practices, applications and social
ramifications which are essential requirements for any fully literate individual of the 21st
century. NATS courses also enhance important critical thinking skills, including those
associated with basic numeracy and scientific literacy.
NATS 1740, Astronomy, makes familiar students with the most interesting topics in
astronomy, from the historical development of ideas about our universe through to the
modern-day search for exoplanets and the origins of our universe itself. Some fundamental
concepts in physics are discussed at an appropriate level to allow a deeper understanding of
the world; for example, how planetary systems form, how stars evolve and how the large
assemblies of stars in galaxies are maintained. Finally the expanding universe and the Big
Bang theory are explored, along with a discussion of dark matter and dark energy. If time
permits, a discussion on the possibilities of life beyond Earth (the science of astrobiology) will
occur.
Course Learning Outcomes
Upon successful completion of this course students should be able to:
1. Explain the scientific method, to communicate basic scientific ideas clearly and
concisely both orally and in writing.
2. Discuss the differences between the ancient and modern models of the structure
of the universe and appreciate why the modern model has more predictive power.
3. Describe the significant events that have occurred in the history of the universe,
including the Big Bang, the formation of the Solar System and the development of
life on Earth.
4. Discuss the nature and characteristics of the principle elements of the universe,
namely planets, stars and galaxies.
5. Demonstrate critical thinking and reasoning in developing ideas and in assessing
reference sources, as well as to criticize constructively.

2The Group Assignments (GAs) will require each group of students to complete collaboratively an
assignment in class on selected Thursday. The aim of each of the 4 assignments will be to further
enhance the understanding of certain key topics in the course. The total weight of all 4 assignments is
9.0%. The GAs are subject to the “80% Rule.” This means that only the best 80% of these
assessments (3 of the 4) will count towards the overall grade. This allows students to miss up to 1
GAs (e.g., due to illness, forgot to submit, etc.) in the year without suffering negative consequences
and without having to supply formal documentation. No make-up options for missing any GA will be
available.
3In-Class Questions (ICQs): during lectures, a series of multiple-choice questions will be posed by the
lecturer and answered by the student using an app on a smart device (about which more information
will be provided elsewhere). This will provide real-time feedback on studentsunderstanding of key
concepts. The total weight of the ICQs is 7.0%. The ICQs are subject to the “80% Rule.” This means
that only the best 80% of the questions posed will count towards the overall grade. This allows
students to miss up to 20% of the ICQs (e.g., due to illness, forgot to submit, late to class, etc.) without
suffering negative consequences and without having to supply formal documentation. No make-up
options for missing any ICQ will be available.
1Online Unit Tests (OUTs): A series of tests provided by the textbook online website called “Connect”
to practice and learn each chapter, are all subject to the “80% Rule.” This means that only the best
80% of each of these multiple-choice assessments will count towards the overall grade. This allows
students to miss one or possibly more Assignments (e.g., due to illness, forgot to submit, etc.) without
suffering negative consequences and without having to supply formal documentation. No make-up
options for missing any OUT will be available.
5Two main exams will be predominantly multiple-choice format using Scantron answer sheets and their
dates are already set as mentioned in course outline. It is a student’s responsibility to be available for
these examinations (They are during the class time). The exams will be written on campus. It is a
serious matter to miss an exam and may result in a mark of 0 being awarded.
Please note: In order to be consistent and fair to every student, individual grades are not
negotiable and there will be no “extra credit” assignments, period. Please contact the
4
instructor about a grade only if there is a clear error (calculation, clerical, etc.) within two
weeks of the grade being made available to you (normally via Moodle).
Course Materials
The course lectures will closely follow the textbook, “Explorations: An introduction to
Astronomy” by Arny & Schneider (8th edition) which is available in hard-copy or electronic
format (available at the York University Bookstore or on-line) The textbook in whatever format
you choose is strongly recommended. An access code to “Connect” will be automatically
packaged with the textbook (at no additional cost) or available “stand alone” at a cost.
(“Connect, is a required resource for completion of online quizzes, 27.5% of the total grade.)
Along with the textbook and lectures, a number of activities designed to enhance the
student’s understanding of the more complex issues discussed in the course will be provided
on the course Moodle website.
Tutorials/Labs
This course does not have a lab component or tutorial sessions. It does, however, include a
Group Assignment component that will take place during lecture time on specified Thursdays.
These Group Assignments, GAs, (4 per term) will involve groups of students to work together
on assignments.
Students will be organized into groups normally comprised of 4 students per group. The
composition of a Group will be based upon random selection via Moodle before each GA or
spontaneous grouping in the class. Announcements regarding the timing of this process will
be made shortly after the term commences.
The GAs will count towards 9% of each student’s final grade.
Observing Project
Each student will be required to complete an observing project consisting of acquiring an
image of a constellation using a digital camera and providing relevant supporting
documentation for both the image and the constellation itself that will be uploaded as a PDF
to the course website. The constellation will be selected based on the student’s York
University number and will be accessible during the course.
The Project will count towards 6.5% of each student’s final grade.
Course Content and Format
Students who are registered in the course should have automatic access to the class
(Moodle) website following Passport York authentication (moodle.yorku.ca). The
website will contain all important administrative and curricular information for this
course and should be consulted frequently by the student; daily if possible.
The curriculum consists of 19 Chapters from the textbook which are bundled into 6
Parts in the text. The Essential Cosmic Perspective will be covered over a time-span
of 24 weeks. Thus, students can expect to cover, on average, one chapter every
week or so. (Chapters are not of equal length.) Of importance when it comes to
assignments, is the division of material into Units, groups of Chapters that will be
tested together: 4 Units will be covered each term. At the conclusion of each Unit
there will be a Unit Completion Assignment. A supplementary video on the course
Moodle website will illustrate how you might reasonably approach the materials
5
provided for each Chapter and Unit on the website.
Each of the 8 Units in the course is structured similarly:
o A list of Learning Outcomes for the Chapters
o The “Important Questions” that will be discussed in the Chapters
o Any additional articles or cool links to assist in the understanding of material
o “So you want an A” provides resources that help clarify some of the most
important concepts in each Chapter, and material that will enrich the student
learning experience
o The Unit Completion Assignment (UCA), a predominantly multiple-choice
assignment for marks. It will be held at the conclusion of each Unit.
A Unit will be considered “open” for a well-advertised amount of time (nominally until
the Unit material is completed in the lectures). While a Unit is “open,” students may
attempt its quizzes and activities for marks. Once a Unit is closed, while all the files
remain accessible for study and review purposes, it will no longer be possible to
complete a quiz or activity for marks.
Math Content
This course does not rely upon mathematical skills beyond those normally found in the Grade
10 curriculum: simple algebra and geometry. There is little emphasis placed upon
mathematical manipulation. For example, the end-of-term exams will contain 100 to 120
multiple choice questions of which about 5 will require the use of mathematical concepts
discussed in the course. Scientific notation, the use of power of 10 notation, is discussed as
numbers in this course are both extremely large (scale of the universe) and very small (size of
the atom) and warrant an appreciation of how to read such numbers.

Copyright and Intellectual Property
The class (Moodle) website is a proprietary repository of materials produced explicitly for the
use of students registered in this class. Moreover, the (digital) material on the class website
is the intellectual property of the instructors and much of it is under copyright by the textbook
vendor. This means that it is unethical and illegal to share this material directly with students
not registered in this class or to external websites.

Academic Honesty and Integrity
Academic honesty requires that persons do not falsely claim credit for the ideas, writing or other
intellectual property of others, either by presenting such works as their own or through impersonation.
Similarly, academic honesty requires that persons do not cheat (attempt to gain an improper advantage
in an academic evaluation), nor attempt or actually alter, suppress, falsify or fabricate any research
data or results, official academic record, application or document. Finally, academic honesty requires
that persons do not aid or abet others to commit an offence of academic dishonesty, including
intentional acts to disrupt academic activities.
Suspected breaches of academic honesty will be investigated and charges shall be laid if reasonable
and probable grounds exist.
Academic Honesty and electronic devices during assessments (e.g. exams)
Internet capable and personal storage devices of all kinds must be turned off, including vibrate.
These and any other unauthorized material must be placed under the student’s chair and
should not be accessed at any point during the exam. Failure to comply with directive may be
considered a break of academic honesty.
See http://registrar.yorku.ca/exams/tipsheet
Please familiarize yourself with the full Senate Policy on Academic Honesty, found at
http://secretariat-policies.info.yorku.ca/policies/academic-honesty-senate-policy-on/

https://w2prod.sis.yorku.ca/Apps/WebObjects/cdm.woa/wa/regobs
Note: Students who will have an academic conflict as a result of a religious observance, at any
point in the term, should make the instructor aware of such at least three weeks prior to the
conflict.
For conflicts occurring during an official examination period, please complete the Examination
Accommodation Form available at http://www.registrar.yorku.ca/pdf/exam_accommodation.pdf and
submit to your instructor at least three weeks prior to the final exam.
Student Conduct in Academic Situations
Students and instructors are expected to maintain a professional relationship characterized by courtesy
and mutual respect and to refrain from actions disruptive to such a relationship. Moreover, it is the
responsibility of the instructor to maintain an appropriate academic atmosphere in the classroom and
the responsibility of the student to cooperate in that endeavour. Further, the instructor is the best
person to decide, in the first instance, whether such an atmosphere is present in the class. A statement
of the policy and procedures regarding disruptive and/or harassing behaviour by students in academic
situations is available on the website of the University Secretariat (http://secretariat.info.yorku.ca/).
