Course Description: This course is an algebra-based introduction to physics, covering the
motion of matter and of waves. We will study how to mathematically model the universe,
discussing topics like Newton’s laws, energy, momentum, gravity, waves, and a taste of
quantum physics.
Prerequisites: Physics 20 and Pure Mathematics 30 or Mathematics 30-1. Physics 30 is
strongly recommended. Note: Credit may be obtained only for one of PHYS 124, 144, EN
PH 131 or SCI 100. If one wishes to proceed to PHYS 146 after taking PHYS 124, one
should achieve a minimum grade of B- in PHYS 124.
Required Textbooks:
“Physics”, Custom 2nd Edition, by James S. Walker (in bookstore). Either the Custom 2nd
Edition (sold in the bookstore), the (First) Custom Edition, or the Fourth Edition (from
which the Custom Editions are taken) will be fine.
“Mastering Physics”, which is packaged with “Physics” for new textbooks. Students not
wishing to purchase the textbook will need to obtain a stand-alone registration code, available
in the bookstore or online.
An ’iClicker’, available in bookstore.
Lab manual, available for downloading from the UGL website or the class website.
Structure of Course: This is not a straightforward lecture course. Physics involves more
than just memorization, so I will ask you to participate actively in your learning throughout the course. Before each class, I will ask you to read relevant chapters from the text,
and to complete a reading quiz on the material weekly. During class, I will explain (and
1 of 9
demonstrate) various topics, and will ask you to answer questions using your iClicker, and
to discuss questions with your neighbours. You are responsible for reading the assigned
chapters, which include material that will not be covered in class but may be on exams.
Marking Scheme:
Homework (see schedule at bottom):
7%
Clicker participation:
3%
Final Exam (expected Dec. 11, 9am): 45%
Midterm 1 (on Oct. 7):
15%
Midterm 2 (on Nov. 4):
15%
Labs & tutorials
15%*
Minimum of 50% in lab is required to pass the course. Lab/tutorial material will be
included in written class exams. Final exam schedules are set by the Registrar.
Grades are calculated from the scores of each component, averaged using the weights
specified in this course syllabus. This overall mark is then used to assign course grades.
Grade boundaries will be decided based on a combination of historical student performances and the instructor’s expectations and judgment. Where possible, natural grade
boundaries will be used. The absolute percentage scores to secure a particular grade
will vary from year to year because it is not possible to write exams with consistently
identical difficulty levels. The course average will be 2.62, or B-; this is required by
the department.
Homework will be done through Mastering Physics, at www.masteringphysics.com.
Late homework will not be accepted; the due date is 11:59 pm of the due date indicated
on the schedule. I expect students who add the class during the drop/add period to
have been attending class and doing homework, so joining the class late is not an
excuse for missing homework. The lowest homework grade will be dropped from your
mark. This policy is designed to cover the majority of problems that lead students
to ask for an excusal from a homework assignment. Note that homework will include
reading questions about material not yet covered in class.
On-line homework is a component of this course and is provided by a third-party
company. Please be aware that this company will be storing assessment information
that may be associated with you. If you have any concerns about this, please contact
me.
Clicker Participation counts as part of your grade, and is a key component of your
learning. To register your iClicker, go to iClicker.com, or send me the ID of your
remote and your student ID number and name (this must be done by the last day of
classes to earn credit). Up to six unexcused missed classes will be forgiven.
2 of 9
Laboratory work, via weekly labs, is required to pass this course. The schedule will
be posted at http://www.physics.ualberta.ca/ugl/Schedules.aspx ; labs start on Monday Sept. 16. Missed labs have to be made up during the term. Under extenuating
circumstances (medical, family crisis, etc.), a student may be offered an excused absence from the labs. A maximum of two excused absences are allowed. The student
must fill out an excused absence form (available in UGL shop room L2-069) and hand
it to the TA. if the form is not filled out promptly (within a week of the missed lab),
a grade of ”0” will be assigned to the missed lab.
Midterms will be held on Oct. 7 and Nov. 4 in class. The Final Exam date and
location is set by the Registrar; I expect it to be on Dec. 11, at 9 am. It is your
responsibility to be at the correct location at the right time for each exam. All exams
cover all preceding material, though the second midterm will focus on material since
the first midterm. (More exam details on pages 3 and 4 below.)
Course Exam Policies
Exams are closed book. Bring an approved calculator (see below), a pencil, a photo ID (e.g.
OneCard), and one formula sheet. A suggested formula sheet will be provided to you one
week before each exam, you may add to it or write your own sheet instead (both sides okay).
Exams are multiple choice; multiple versions of the exam are likely to be circulating. You
must give your name, student ID, and the exam version on your ScanTron to receive credit.
If you must miss a midterm (e.g. due to illness), you may apply for a deferral of the midterm
weight to the final exam, by making a Statutory Declaration (available from the Student
Services office, CCIS). If you must miss the final, apply to your Faculty office within 48 hours
of the missed final with a Statutory Declaration, to request to be allowed to take a deferred
final exam. Deferred final exams will be Sat., Jan. 25, 9am–noon, in CCIS L1-047. Deferral
of exams is a privilege and not a right.
Past exams (without answers) are available at the exam registry.
If you are registered with SSDS, it is your responsibility to provide me with a “Letter of Introduction”, and to comply with SSDS deadlines and regulations, available at
www.ssds.ualberta.ca or the SSDS office.
Academic Integrity:
From the University Calendar: “The University of Alberta is committed to the highest standards of academic integrity and honesty. Students are expected to be familiar with these
standards regarding academic honesty and to uphold the policies of the University in this
respect. Students are particularly urged to familiarize themselves with the provisions of the
Code of Student Behavior (online at www.governance.ualberta.ca/) and avoid any behaviour
which could potentially result in suspicions of cheating, plagiarism, misrepresentation of facts
3 of 9
and/or participation in an offence. Academic dishonesty is a serious offence and can result
in suspension or expulsion from the University. All forms of dishonesty are unacceptable
at the University. Cheating, plagiarism and misrepresentation of facts are serious offenses.
Anyone who engages in these practices will receive at minimum a grade of zero for the exam
or paper in question and no opportunity will be given to replace the grade or redistribute
the weights. Any offense will be reported to the Senior Associate Dean of Science who will
determine the disciplinary action to be taken.”
How does academic integrity apply to the different components of this class?
Collaboration on homework and labs can increase learning, so we encourage it. Graded
work, however, should represent your understanding of the material, and should be written
up separately. Details:
Homework: You may work together to complete the homework, but must enter your own
answers into the homework system.
Reading quizzes: These should be done on your own.
Clicker questions: I intend you to collaborate on these questions; discussion of these questions will be a key element of our class experience. To supply answers for credit, you must
be in class with your own clicker. If I or any of my TAs catch someone with multiple clickers,
we may take them all for that class and submit an academic dishonesty report for everyone
involved.
Lab: You will have a lab partner with whom you are expected to collaborate. Your answers
on lab writeups should be your own, not a direct copy of your partner’s.
Midterms & Exams: You must work entirely by yourself with no access to course materials,
besides the formula sheet that you may prepare as you like. You are expected to have photo
ID available on request. A calculator may be used, provided it is not a programmable or
graphing calculator. Bringing an illegal calculator to an exam may be considered an attempt
to cheat. We suggest TI-30X IIS, TI-30X IIB, TI-30XS MultiView, HP 10S, HP 30S, CASIO FX-115MS Plus, CASIO FX-115ES Plus, Sharp EL-520V or EL-520VB as good choices.
Using one of these, or any calculator with a Faculty of Engineering gold calculator sticker
on it, will ensure no problems. Cellphones, iPods, laptops, or any other devices with
remote communication capabilities are not permitted in exams, and their possession will be
considered an attempt to cheat.
