COURSE OBJECTIVES
The objective of this course is to provide a broad exposure to how humanity has created
and applied the language of math to describe basic physical phenomena. Whereas the
class schedule above provides a topic-by-topic list of specific subjects to be covered, the
broader goals are:
* Understand the concepts of electric charge, field, potential and and current.
* Understand the components and characteristics of electric circuits
* Understand the concepts of Magnetic pole, field and Lorentz force.
* Have a basic understanding of electromagnetic waves and wave optics.
* Have a basic understanding of light as quanta, called Photons.
The quizzes and exams, in addition to test student knowledge, also serve as guide for the
instructor to further focus and improve the presentation of the material, both for this
semester, as well as future ones.
ONLINE HOMEWORK
The assigned Online Homework problem sets will be on MasteringPhysics. Problem sets
are due on Tuesdays by 8:00 am starting second week of classes.
Access to MasteringPhysics:
You will need a student access code for the 14 th edition of the book. This comes in the
Student Access Code Card/Kit that may have been packaged with your new textbook or
that may be available separately in your school’s bookstore. Otherwise, you can purchase
access online at www.masteringphysics.com. Access codes are valid for a full academic
year.
1 Access MasteringPhysics through the Blackboard page. There is a link in the main menu
2 If you have a MasteringPhysics account from physics 221 which is less than 2 years old
and did not take 222 until this semester, please contact our Pearson representative,
Carly Harryman carly.harryman@pearson.com, and she will give you a replacement
code at no cost.
WRITTEN HOMEWORK
There will be one written assignment per week. The written homework will not be graded.
Written homework does not need to be submitted. To put more emphasis on written
homework, quizzes will depend on the written homework as well as the online homework
just completed ( the one was due the same week of the quiz).
4
RECITATIONS
There will be one, 50-minute, recitation on Tuesday during any given week (see schedule).
Worksheets:
Worksheet is conceived as a hands-on, interactive activity. Students will work in small
groups on a worksheet or problem set provided by the recitation instructor. Discuss,
sketch, ask, explain, disagree, think aloud… but don’t sit back and wait for the
instructor to solve the problem on the board. Your instructor is there to help you
through the problems, to answer your questions and to monitor your understanding of the
material. Learning is done best by doing, not by watching.
Quizzes:
* At the end of every Tuesday recitation (except first week), a 10-minute quiz will be
given.
* Quizzes will be graded by the recitation TA and handed back to the students in the next
recitation.
* Missed quiz: If you miss a quiz for a university approved excuse (e.g. being sick, being
away due to an ISU related activity), you should bring some document to prove the
reason of your absence to your TA. An Excused Grade will assigned to the missed quiz
(i.e., at the end of the semester your score for the missed quiz will be the average of all
the other quizzes.)
* PLEASE NOTE: The total points associated with quizzes are almost as much as one of
the two mid-term exams. The path to a good final grade is paved by good quiz scores.
LABS
Information about labs (policies, grading, schedules) is posted in a separate Blackboard
page called PHYS 222 LABS (Fall 2016). Access this page as soon as possible to:
a. Read the Laboratory Information and Policies; in particular, make sure you understand
the make-up lab policies.
b. Take the Laboratory Policies Quiz (you need a perfect score on this quiz); and
c. Figure out when your lab section meets for the first time.
Completing all the labs and the corresponding prelabs is required. Failure to do so
will result in an ”F“ for the entire course, independently of your performance in other
components of the course.
The final exam will contain four questions about the labs.
Lab waivers:
* If you have completed the laboratory part of the course successfully during a previous
semester at ISU, you may request a lab waiver during the first week of classes . This is
done through Blackboard.
* If this waiver is granted, your old lab grade will be used.
* You still have to answer the lab questions on the exams.
The importance of the recitation and laboratory classes cannot be over-emphasized. You
will not understand the material in this course if you cannot apply it to the solution of the
assigned problems. The laboratory is essential to your efforts to understand the
experimental foundations of physics as well as of scientific instrumentation.

EXAMS
Mid - semester exams
This course has evening exams, see the ISU Bulletin and/or the following ISU web-page:
http://www.iastate.edu/~registrar/exams/nitexam.html.
Note the exam dates:
Thursday, September 29, 2016
Monday, November 07, 2016
8:15 pm – 10:15 pm
8:15 pm – 10:15 pm
and make no other plans for these evenings. Evening exams are used in this course
so that all students can take the same exam at the same time and thus be graded on the
same basis.
Final Exam
December 12-16, time and day TBA
120 Minutes.
If you have a conflict with the scheduled time for the final exam or any other reason why
you cannot take it at the assigned time, you must notify Dr. Al-Saqer before 5pm
Monday, November 28th so that an alternative arrangement may be found.
* Room assignments and instructions will be posted and discussed in advance
exam.
* Material to bring to the exam:
− a number 2 pencil,
− a scientific calculator. Graphing calculators are not necessary but
used. Laptops, cellphones or PDA’s are not allowed.
− your student ID card.
* Each exam will include the values of any physical constants you may need, a
sheet and scratch paper.
* Exams will be multiple-choice.
* Each exam will include the values of any physical constants you may need, a
sheet and scratch paper.

Make-up exam:
* A single, end-of-semester, make-up exam will be allowed only in exceptional
circumstances, such as illness, family emergencies (not anniversaries, family vacations,
etc.), or official university-sponsored activities.
* Students who know in advance that they will miss an exam as a result of one of these
university-sponsored activities must explain the circumstances to the lecturer well
before the exam and seek permission to take a make-up exam. After the fact, such
permission will not be granted.
* Students who miss an exam because of illness or other unforeseen emergencies should
send a message (by phone, voice-mail, e-mail, or through a friend) to the lecturer or
the course secretary before the start time of the exam in order to receive permission to
take the make-up exam.
* This make-up exam will be held during the week before finals week and will be a
comprehensive exam.
* Clearly only one exam can be made-up in this manner.

The above point scale for letter grades for the course will not be raised, but may be
lowered (but only slightly.)
A failing course grade (F) will be given if:
1. any laboratory has not been satisfactorily completed, or
2. the student has engaged in any form of academic dishonesty.
* Homework scores: Homework is an investment –the “direct” credit from homework is
only 7.5% of the final score, but this is the most important learning tool in the course.
Homework is your opportunity to make mistakes and learn from them. Then you will be
able to answer the exam and quiz questions correctly, which carry 75% of the total
points.
* Recitation scores: The precise number of recitation points you receive from your
instructors during the semester will not necessarily be the same as the number that
counts towards your final grade. Some instructors grade "hard" during the semester
and some grade "easy". Thus, in the interest of fairness to all the students, scores for
hand-graded material may be slightly adjusted at the end of the semester to
compensate for these differences. This means you will not automatically get a higher
grade because you have an easy grader, or a lower grade if you have a hard grader.
* Grade book: You should regularly check that all your scores are correctly entered in
the online grade book on Blackboard. It is your responsibility to bring any problems
to the attention of your section instructor immediately.
* Exam scores: If you believe there has been an error in the grading of an exam or in
the final grade assigned to you, you need to contact Dr. Al-Saqer no later than one
week after the results are released.
DROPPING THE CLASS
If you decided to drop the class, please bring the form to the course secretary, Deb
Schmidt, 12 Physics (Main Office), debs@iastate.edu, 294-4936.

STUDENTS WITH SPECIAL NEEDS:
If you have a documented disability and anticipate needing accommodations in this course
(for lectures, recitations, labs, or exams), please request that a Disability Resources staff
provide you with a SAAR form verifying your disability and specifying the accommodation
you will need. After getting your SAAR form, make arrangements to meet with Dr. Al-Saqer
as soon as you can.
STUDENT ASSISTANCE
There are several opportunities for students to receive assi stance with the material of this
course:
* Room B54 Physics will be the Physics 222 Help Room. The staffing schedule will be
posted on the door and on Blackboard.
* Instructor office hours.
* Discussion board on Blackboard.
* Supplemental Instruction (SI): http://apps-dso.sws.iastate.edu/si/
* Tutoring: http://new.dso.iastate.edu/asc/tutoring
HOW SHOULD I STUDY FOR THIS CLASS?
It is to your advantage to work with other students to learn the material. This can often
help you to do better on the exams and homework. We encourage you to work together
and perhaps form a study group. You may meet in the Physics 222 help room, if you wish.
Please see the academic honesty statement for guidelines about working on homework
assignments in a group.
* Keep up with the class! In physics, the material often builds upon what was covered the
week before. If you start falling behind, do something immediately.
* Read the indicated reading assignments before each lecture. The reading assignments
are essential to understanding the material presented in the lecture. A second reading
after lecture helps cement key ideas into place.
* Solve problems! It is the single most important activity in a physics class. If you
cannot solve the problems, you did not really understand the concepts. In addition to
homework, recitation is devoted to problem solving. Redo (without looking at the
solution) the examples shown in lecture.
* Be honest to yourself: if you solved a problem without really understanding why what
you did worked, it is a waste of time (chances are that you just got lucky.)
* … Reflect on problems you solved correctly. Identify key points in strategy used, key
concepts and math skills required. Revisit the same problem later on and realize the
time needed to solve it compared to previous time.
* Check the solutions posted online. Be sure you understand all of the concepts as well as
steps associated with each problem.
* Complex problem solving requires order: Always work with a pencil and paper, and be
neat, even if the problem does not need to be turned in. When problems involve many
steps and concepts, it is easy to get lost if all you have is a collection of numbers
randomly scattered on a sheet of paper. Do not try to do calculations in your head
unless they are trivial. Label quantities in a meaningful way (don’t call everything x!)
Keep your work for future reference (see next point in this list!.)
* Learn from your mistakes: focusing on your mistakes is the most effective way of
identifying misunderstandings, weak areas, etc. Keep a list of the problems you missed,
or did not completely understand, or simply struggled with. Make sure that you
understand the solution, and make sure that you understand why what you did was
wrong! A few days after all this, try to do the problem again.
8
* As needed, reread the chapter summaries in the textbook. Review the appropriate
sections and/or go over your lecture notes.
* Solve extra questions and problems in the textbook (the odd numbered problems have
the answers in the back of the book.)
* Join a study group. You will benefit both from other students’ insight and from how
explaining something to another person tests and refines your understanding of a topic.
* ... but be careful: being able to follow a problem solved by another person is not the
same as being able to solve it on your own! Group work should always be followed by
some individual work.
* Use the help room. This is the perfect time to get one-on-one time with an instructor
